Alright, I have been doing a lot more welding lately. I was employed by my neighbor to make up a couple small things for his race car (brake and clutch master cylinder mounts, a guard for the master cylinders, misc. brackets etc.) Just small things that aren't really bearing a lot of weight as I don't completely trust myself to do anything structural. I have been welding for a year or so, pretty much self taught. I turn sixteen in February so now I can go do some classes at the community collage once I invest in a good auto-dark helmet.

Anyway, most of the stuff I have been doing lately has been done and out the door, so I laid down this bead on some scrap so I could get a picture as to get some advice. These pictures are both of the same weld. Sorry for the poor quality, cell phone camera. This is with Lincoln E6013 and a shitty "Mastercraft" (Campbell Hausfeld) 70A stick welder I got from Canadian Tire for $100. It's certainly not even remotely decent by any means, but I have made it a personal goal to learn how to lay down some decent beads with the equipment I have before investing in something better.

This is pretty much just an average bead for me. I've done much better, and much worse. But overall this is what most of them look like (minus the hiccup at 1/3 of the way through). Any tips or advice would be greatly appreciated!

Well, at least you're running 6013. Excellent choice of rods, especially for a beginner.
First, and I really can't see the view I need, you need more heat. That bead apears to be laying on top of the metal without much penetration. You either need a smaller diameter rod or a bigger machine.

For a better indication of what your bead is doing, hacksaw across the metal and weld, and polish up the cut end. A little vinegar rubbed onto the polished surface may be necessary to see your penetration better.

Your travel speed ain't half bad considering the machine you're trying to weld with. What diameter rod are you running and what amperage?

I’m with Franz; good effort. To me the finish looks better than the start, I’m guessing this is because of the accumulated heat that built up in the steel as you where welding, supporting the smaller rod or more heat advice.

PS: I couldn’t weld like that when I was 16.

Rods are 3/32" IIRC (does that sound correct? I'll run out to the garage and check). Smaller than standard size rods, but it's as big as this machine will handle. The welder has a "LOW" (like 40A or something) and a "HIGH" setting (70A) I use smaller rods for the low setting on really thin stuff. Maybe I should try out using the smaller rods on the high section, hhhmmm...

Thanks for the advice, I'll run out and confirm the size in a few minutes.

I have no problem buying a better machine, but I need to get the electrical service in my garage upgraded first. Even this machine will pop the breaker if I run it too long on "high".

I agree 6013 is a great electrode to start with. Burns down real nice and is very controlable. The best thing to do is keep buring rod. The more you do the better you get. One other word of advice, I always try to plant an elbow to the welding table to get a bit of stability.

Franzİ
12-28-2007, 02:42 PM
Running 3/32 on 40 amps is damn near a chalenge to keep the arc burning.
Under those conditions I'd be willing to bet a whole dollar there is little if any penetration and the deposit is pretty much sitting on top of the base metal.
Give the 70 amp setting a try.

Also keep the arc as short as possible.
There is only so much you can do with the machine you're using.

I'm running the 3/32" on the 70A right now, which is what I did that weld with.

I was saying I could use the next size smaller rod (the ones i normally use on 40A) on the high (70A) setting to see if I can get more heat, since that appears to be the problem (not enough heat, poor penetration).

rickairmedic
12-28-2007, 04:26 PM
Brendan I would say thats a good start trying the smaller rods on the higher setting and like Franze said try cutting through the weld to see what kind of penetration you are getting also you can try the vise and BFH method of testing practice welds .

Honestly, not in any apreciable way I can think of.

Your machine's lack of power is too much of a handicap to overcome by preheating. You could try 1/16 6013 if you had some, but I would advise against buying any because 1/16 is like tryin to weld with cooked spagetti.

So basically you're saying I need to get the electrical service in the garage upgraded, then upgrade my machine.

I often use my friend's dad's Miller stick welder. That thing is sssooo nice, so much better and easier to use and the quality of my welds reflect that.

Rhere is no substitute for output power on a welder. You can't have power out without power in.

Now, if your mom has an electric (hydro) stove or drier, and you can get away with it, a decent extension cord might get you by.
Probably be a lot easier to run power to the garage though.

How thick is the metal you are trying to weld? from what I recall last time I was arc welding I had the machine set to around 160 with a 1/8" rod on I believe 1/4" steel That is what my memory is telling me but it was about a year ago last time I burnt a rod. Point is you have no where near enough amp's or long enough duty cycle for anything thicker then 1/8 inch plate try selling that machine off to some yuppie on ebay and pick up a old lincoln buzz box you can generally find them for 200$ or so most anywhere ac/dc at that. You will find that you're welds look better are easier to lay and will actually hold something structural together without so much worry You seem to have the basic's down and you're limitation is the machine keep up the good work :thumbup:

I never stepped back to learn stick welding. I did it a few times when I did commercial glass work, but I never did it to the extent of being good at it. I am a d1.1 and d1.6 certified welder in MIG. Here is acouple pics of my MIG welds.

The bottom piece is .125 stainless plate, the top piece is .250 stainless. .035 stainless wire using a tri mix. Heat was set at 26-27 amps and wire speed was set around 5-6 and i push my welds. Pushing your weld keeps the area hot and the weld really pushing in.

The machine is a Miller 300 arc welder with wire feeder added. It is a 480volt machine I use at work. I was showing a guy who doesnt know much about welding, how to weld on that piece there.

I have a lincoln 140 in my garage and a hobart 180 coming soon (garage landlord hasnt ran 220 yet anyways)

As so my method, I have learned a few over the years. One has been just an arc and push method. I think it gives a washed out look, not very neat imo. For the welds above and how I weld 99% of the time, as I push, i push forward some and then pull back half of what I pushed forward. No circles, no half circles, etc. On a welder this big, you dont need to as the wire and heat is so sufficent, it fills the area on its own.

On my 140 at the shop, I do use a half circle method. But I still push and everything the same as above. I do that b/c it being a 140 and wire being .035 (mig wire here and mig gas), it doesnt puddle like the bigger machines do, so you have to take your time and fill the area you're welding, your self. (at home, my machine burns very nice up to 3/16 and will do 1/4 with a bevel and welded on both sides)

Here is are acouple welds using my 140 at home.

Thanks for the info and pics.

I learned on stick so I 'm having a hard time learning to push my welds and not getting a puddle with the small machine makes getting a good bead a lot harder IMHO, also I wonder about the penetration not being sufficient.

Your comment about the larger mach. running hotter and getting good penetration is good to know. I have a Flat Out Eng. corvette sub frame to install in a '50 Chev truck and have been wondering if the 120 will do it?

That looks like a huge "c" notch, what are you building?

Also what kind of helmet are you using? I'm using an antique with a gold lens and I see double half the time or can't see at all , so I've looked at a Digital Elite. When I can see my welds don't look to bad so figure money spent there is well put. Any pros cons or otherwise.
Thanks Mark

I don't know Franz, that " point nod-flip hunt for arc" I've never mastered, and I haven't heard of any pro welders still using the old school helmets, ( maybe in out of position work once in a while)

What short comings do you see in the auto darks?

Franzİ
12-30-2007, 04:47 PM
Well NOW you do know one who is still using the gold lense!

I've looked at autodarks since they were $900+ a copy, and have yet to stumble across one I liked.

I started looking thru green glass, and moved up to gold probably in the 70s, and I love it. I just bought a Jackson nd moved my gold filter plate into it from the old helmet.

I have a fairly good understanding of how the LC array functions in an autodark, and it still doesn't impress me. Then again, I've already had the fun of getting an eyeball laser welded by an overpriced eyedoctor, so I might have be a little more hesitant than the average guy.

When you have a scratch in a gold plate, you know it, and scrap the plate right quick if you're smart. A LC array can easily have small failures and you won't notice them until after the damage is done. I still don't see NASA converting them space helmets to autodark for that very reason.

About the only place I see a use for autodarks is a production weldor doing TIG all day.

Point/nod is all part of the craft, and something you learn. After a while it becomes so automatic it's just like arc length, you don't think about it, just do it.

Most people have problems with seeing what's on the bright side of the helmet because the lense is dirty.

Being stock frames are only .120 a good 110 will work. The method is where it will hold, or will not hold. What I would do is if you can, slide part of the subframe into the old frame. If that isnt able to be done, then have a gap about the thickness of a nickle (I actually put a nickle between my butt joints to space them), when you burn a good bead, cut a square peice that you place over that weld in a diamond pattern and weld that on. It is what we call a 'fish plate'. This will make that joint damn near bullet proof.

If you dont feel comfy with the 110, then a good 220 under a grand will do the job perfectly. The Hobart Handler 185 is 7XX and it will burn 3/8 all day. We use such huge machines because the company I use to work for, did production work and the 480volt machines are 100% duty. I have never shut off my 110 lincoln and I have welded with it for hours on end. The duty cycle is based off of solid runs.. i.e. they say you can weld every 3 minutes out of 10, well that is 3 SOLID minutes of the trigger pulled.. i've never laid a 3 minute long bead and I do 3-4 foot long welds on some of the things we do.

That c notch is so huge b/c i backhalfed my truck, the frame extends straight out from the factory (basically the backhalf lays on the ground also) then the notch starts and it is notched for a 30" tire. Will a 24 fit on my nissan? barely, but I wont ever go that route. I had planned on it, but I will put it back together, stockfloor bodydropped on 20's and get rid of it. I wanna get rolling on my rod. Mini's are a waste of coin.

At my shop I have a harbor freight auto darkening. The lense is green and actually a really nice hood for 50 bucks. I've used SpeedGlass hoods that are 450 and at work I have a 70 dollar 'old school' hood with a gold glass lense in it. I would much rather have the hood at my work then the one at my shop, only b/c after 2 years of adjusting it (it liked to loose adjustments every so often) it is stripped and so the hood just falls to the chest most of the time.

It is hard to get into the groove from push to pull. We had a school come down and certify us at work and apparently this school is suppose to be one of the best in the northeast and the instructor was telling us with a mig, if you pull, the weld can not be as strong due to nothing is really help force the wire through into the metal since pulling allows for it to puddle onto into of puddle in like pushing does. Which I knew for while, but never seen proof of it.

Good luck learning to really get good on a MIG. Next on my agenda is TIG.

markb1
12-30-2007, 07:44 PM
Franz, I'm going to give the old school Gold a second chance, maybe a new helmet that fits, flips better, clean lens, etc.

Fab Shack, thanks for the tips, I was about to give up on the mig but have been making progress.
If you've ever gas welded you'll find tig easy and a lot of fun. I did a little stainless work and loved it, you get a lot of control of your puddle kind of like playing with candle wax.

I was looking for an excuse to buy a new helmet and new welder but I know the problem is really operator error, so thanks to both of you for encouraging me to stick with what I have and improving my skills.

I make no claim to be God's gift to welding, but the guy who taught me sticks together nuclear reactors - you aim to push, whenever possible, to ensure the puddle is well shielded by gas. The idea that the MIG wire feed somehow won't deposit metal into the puddle if you pull is just bizarre.

Great welding information here! I never heard of a weld called out as "push" or "pull", I learned them as "up" (same as push) and "down" (same as pull). Up welds are trickier but stronger.

I have here a Lincoln 225 stick welder. I've built stock cars with it, fixed things on trucks and cars, made barbecues, etc. I also like the E6013 rods for general purpose. I also use E6011 for heavier welds, but it spatters like frying bacon and I never use it for overhead work.

Also, don't be bashful about using heavy amperage. I do most of my welds in the 110-140 amp range with 105-110 reserved for thinner material. Just hold the rod in real tight to the work, once you pull back on it, the required voltage shoots way up and you end up blowing a hole in the work.

Welding is 2 things, practice and being in a comfortable position. I have one of those instant-dark hoods now that is a great invention. Just a flip of the head and it's down, nice and light weight too.

But do read up on welding, there are a lot of books around and courses are available in local colleges and schools. I learned back when I was 16 in high school and took a course in automotive college when I was 19.

Try welding with 7018 Bob. It has alot less spatter than 60 series wire.

Hey Tox lay the specsheet for 6013 and 7018 side by side and compare the numbers.

Most spatter is caused by improper technique with 6013.

Hey Tox lay the specsheet for 6013 and 7018 side by side and compare the numbers.

Most spatter is caused by improper technique with 6013.

I've welded with 6010, 6011, 6013, 6022, 7014, 7018, and 308L (for the stainless jobs). While my job primarily calls for 7018, I have cheated in the past using 601x to fill bad gaps when fitters are on the job, and the inspectors aren't looking. While i find it (601x)easy to weld with, I feel that 7018 lays down a nicer bead, and is somewhat easier to control. I don't know JMHO, or because it's (7018) what I've used the most over the past 12 years it's what I'm more profficient with.
But for argument's sake, and for those who don't know, let's decipher the meaning of a SMAW electrode number Let's use E7018H4R as an example.

E- electrode

70xx- weld tensile strength in thousands of pounds. So 70= 70,000 psi

1- The "1" designates an all position electrode, "2" is for flat and horizontal positions only; while "3" indicates an electrode that can be used for flat, horizontal, vertical down and overhead.

18The last 2 digits taken together indicate the type of coating and the correct polarity or current to use.
18-iron powder low hydrogen-AC or DC+

H4The "H4" is the diffusible hydrogen designator, which indicates the maximum diffusible hydrogen level obtained with the product.

R"R" stands for the moisture resistant designator to indicate the electrode's ability to meet specific low moisture pickup limits under controlled humidification tests.

E6013
This all-position, AC electrode is used for welding clean, new sheet metal. Its soft arc has minimal spatter, moderate penetration and an easy-to-clean slag. Lincoln Fleetweld® 37 is most common of this type.

E7018
A low-hydrogen, usually DC, all-position electrode used when quality is an issue or for hard-to-weld metals. It has the capability of producing more uniform weld metal, which has better impact properties at temperatures below zero. The Lincoln products are typically Jetweld® LH-78 or our new Excalibur® 7018.

Back in the 70's I went to VoTech for welding and also worked in a local shipyard in Florida and as I learned;

Actually the: E-6010/ E6024 / E-7018 E7024 / E8011 / E-9011 / E-10011 / E-12015

"E" is for "Electric Welding"

the second # "60-70-80-90-100-120 etc. is for tensile strength x1000

the third #
"1"= All positions
"2"= Horizontal & Flat
"3"= Flat only

the fourth # 0-9
Shows special characteristics of the rod like; polarity, rate of depostiton, penetration, even bead characteristic (convex-concave),etc.

In addition to this, there is also color coding by different manufactures.

I don't stick weld much any more, mainly just TIG and some MIG, but I have been at it for 30+ yrs.

Tox, if you look at the old Murex book instead of Lincoln's book there are some interesting realitys. You sound like a pipe weldor from the statement about sloppy fitters.

6010 & 11 or 5P and 5P+ are both fast freeze, and excellent for filling in gaps. Neither are comparable to 6013 or 7018.

6013 & 7018 are capping rods in the pipe business put there for additional mechanicle strenght. The root pass itself should be sufficient to keep the liquid or gas inside contained.

The as welded strengths of 6013 and 7018 come up very close to each other, and 7018 falls below the 70,000# as welded. 7018 ia also a LoHy rod, and a pain in the ass rod unless oven stored.

I contend the majority of people in the US burning 7018 are doing so as a result of advertising, and not for any good reason. That includes "engineers" specing 7018, after all no "engineer" is going to risk deviating from what 1000 "engineers" before him have speced.

In Europe the capping rod speced for pipeline work is 6013. They don't seem to be having a lot of problems from it.

Naw, bridge/structural Ironworker. Hence the overuse of 7018. The 60xx trick I learned from a pipefitter who worked with us.

7018 is also a LoHy rod, and a pain in the ass rod unless oven stored.
Actually, while they say it should be oven stored, I was just welding with 3/32" 7018 wire ,today, that has been out of the can for about 3 years. No ovens, no problems. It's what I'm used to burning.

Oh doG a fugitive from a SubArc shop. No wonder you're easily confused.

Never a shop weldor(unless you count my garage). Always in the field.
Shop guys pretty much use innershield or mig these days.

If you never ran a SubArc, be very very happy. Sub is making a comeback again, and there is a hell of a lot more being used today than there was back in the 80s.
As long as you ain't the poor buzzard with the broom & shovel it ain't a bad process.

CAT retired all the old guys from their cylinder plant because the new MBA was sure there was a better process than sub, and now their failure rate on cylinders is 50 times what it was back when them old farts subed them. They even went with 5 robot plasma welders to solve the problem cause the brilliant engineers & salesmen said it would. The plasmas got sold off as surplus, and they still can't make cylinders in Illinois.
Them MBA fellows have their finger on the pulse of the situation though.

You are doing OK for a beginner, but I would caution your use of 6013. It is a lower-penetration "sheet metal" rod; its bead can look pretty good, but it does not, by design, penetrate real deep. If I may suggest, run 6011 (on AC) or 6010 (on DC) if you need penetration, (and you usually do). With practice, you will smoothen out the weld with these rods and in the meantime, IMO, get a better product. Just be careful to not leave "wagon tracks" with 6010/11 (unfilled valleys along the edges of the weld) by running along too quickly, and keep your arc as short as you can. Their arc can blow molten metal around pretty well and make a mell of a hess. The wagon tracks are evidence that it is penetrating. Compare the arc you get (visual and auditor) w/ 6010/11 vs 6013. Are you running DC +? Here is one link you can check out. Keep enterprising!

JK, care to get specific with what you define as shallow penetration, and sheet metal?

While you're at it, kindly explain how you comingle fastfreeze rods into the same category as 6013?

F: No, I can not provide a definition of penetration, as I do not do scientific research on electrodes. I just go by (1) experience, (2) what other welders say, and (3) what "the literature" says, like the link I provided that states "mild penetration". Here is a quote from PART OF Lincoln Electric's data on 6013: "Here’s a terrific all-position electrode for low amp welding on sheet metal..." By all means call them and ask for a definition; to me, it means "thin stuff that you don't want to burn holes in", and that is good enough for me. I encourage anyone interested to research thoroughly whatever they do, part of that being reading banter on internet forums. As far as "comingling" (however you spell that) I was only offering a caution about a particular electrode for a particular application, and did not intend to get into a thorough investigation of all aspects of all electrodes. That is a rather large topic. I hope this clarifies my interest in offering an opinion. Pls feel free to recommend whatever electrode you so desire; it's a great, free country, ain't it? Have a happy. j

First, yo ought to learn what Sheet Metal is. 1/8 6013 in the hands of a weldor can deliver a full penetration weld on ¼" sheet.

6010 & 6011 are fast freeze electrodes primarily used for root pass on pipe work and in situations with crappy fitup.
They are all position, not all purpose, and both are miserable rods for a beginner to try learning with.
While I'm thinking of it,
""Just be careful to not leave "wagon tracks" with 6010/11 (unfilled valleys along the edges of the weld) by running along too quickly, and keep your arc as short as you can.

BULLSHYT!
What you call wagon tracks are a sign of excessive current and an inexperienced operator. They are a guarandamnteed reject of any weld displaying them, and can easily be seen on Xray. Oh, just so you can run tell the so called Welders you learned from, the problem isn't called Wagon Tracks in the welding industry.

Boy, you don't mince words, do you? That's OK; I'm a big boy. Nice to have access to an expert; I will pass this info on. Take care. john
