what are you working on, Abeo?

 

[superspec]

it aint pretty but as long as it works and you learned something in the process you win! good job.

Re: Been missing my tig

I did some tig welding last weekend on the swing out door bars for my 69 mach one. Been years since I've used a tig, but I suppose it's like riding a bike. The tungsten was moving so much I thought I might have Parkinsons disease. Half my life ago at age 29, I could lay down a nice bead, but I can live with these. I used my brother's Miller syncrowave 200 as I sold my last tig, a new Miller Syncrowave 180, which I never used back in 2010. I bought my first tig back in 1995. It was a used Linde 305, too big for my needs but couldn't complain for $400. I've been searching for a used machine as I sure do miss having a tig.

Nice work. I shake with a 35mm camera. The brain just needs a little retraining.

I got a small job from a tech company that wanted boxes to mount on their scooters to carry their iPads and such.

Thanks Robert. I should be taking possession of a used Miller this weekend, and start losing the shakes.

Can I throw out a little hint...?

With that gauge of aluminum, do your joint style without any "filler rod" and some more "heat." Either, "preheat", or the "dial."

Congrats, of the "Piece Work" job.

Fusion welding aluminum usually ends up pretty poorly, especially outside corner joints. Do you have any pics where you have done this?

I agree. If I don't use filler on aluminum it cracks. Maybe there is a trick to it.

Lucky *** birds.

 

[bon3s]

For piece work such as that for a paying client, I agree Rhyno. You want a more 'finished' professional edge.

That said you could of obviously ground it down and put a small bevel on the edge for a very nice looking piece.

I now have this cartoon in my mind of the birds using the spiral as a slide.

I agree about it looking professional but I disagree about the method. I don't think fusion welding is ever the answer except maybe for tacks. But I find it almost impossible to weld aluminum without filler with no cracks in the weld.

 

[Toolhorder]

Here's a cast aluminum repair i did a while back. don't do a lot of aluminum, so i was pretty happy with this.

What did you use to repair it? Tig? Mig spool gun for alum? I have a early CB750 engine with a broken off motor mount on the case I want to try and save and weld just like you did.

There are many orbital welds on tubing that would disagree with your stance on fused welds. I do agree with you in this instance though. A fused weld for those corner joints is a cluster and not good practice.

Let me correct myself. I think that manual welds need filler material.

I agree ... it's hard to get a good looking fusion weld on a right angle corner joint. By putting a radius on each sheet and hammer welding the joint together you can get a good finish without using filler rod. Of course in the case of Robert Hall's client they may not have wanted a radiused corner.

This is steel (vs. aluminum) but I hope it shows that corners can be radiused and hammer welded with good results. I used no filler rod in this and the weld is along the crown of the radius ...

I don't think it is hard I just think it is piss poor practice.

 

[PCO6]

I think it gets harder as the gauge gets thinner.

 

[zkling]

Fusion welding of aluminum, especially manually is an entirely different animal than steel or other ferrous alloys.

Please do this with aluminum of the same thickness and post results.

Finished welding and painting the first of nine frames to replace the warehouse style shelving frames of some Rousseau cabinets I have in my shop. Just need to finish the cabinet that will be inserted in the top section.

I think my post was clear that I wasn't trying to compare aluminum and steel welding. I know they are quite different - steel is easier. My point was to show how radiusing the edges makes it easier to fusion weld a corner than to do it at right angles, especially with thinner gauge material. Assuming you have access to the back side it's easier to planish a radius than a corner and make it look better.

That looks great. By "nine" frames do you mean you have 9 Rousseau cabinets? Those are great quality cabinets.

Correct, I have 9 cabinets and they are excellent quality. You Canadians must be keeping the quality of these a secret as i was able to buy all nine at auction for what most people pay for one Lista!

I am changing to welded frames so that they are more rigid than the warehouse racks and so that I can add some leveling feet and doors to keep things hidden to get a cleaner look.

 

[Robert Hall]

To add to the discussion, I presented one with a fusion weld and one with a raised weld. Overwhelmingly the raised weld won out. They liked the industrial lookadd their offices are a warehouse.

In following some of David Gardiner's work (UK Coachbuilder), most of his panel fabrication is done using O/A gas welding; fusion welding on steel, and using filler on aluminum. His reasoning for the difference:

.... when gas welding aluminium it is important to have good welds so that you don't get flux inclusion, if the weld is undercut or has holes or imperfections flux can be trapped in the weld and cause problems with corrosion and problems with the paint later.

There is not that much build on the weld and it sands down very easily. If you look at the panel you will see that there is almost no distortion so it does not take too much dressing to smooth the joint. This is the welding process is showed on the DVD.

When welding steel it is a different thing, distortion is more a problem so the way I show for steel helps to keep the distortion to a minimum.


It's less work to dress out a weld on a panel like this than to do loads of shrinks by hand and have to dress out the resulting damage and distortion. If you don't put the marks in you don't have to planish for hours to get them out. I put all the joint in the same places as they were on the original panel.

David

I believe the primary reason he uses fusion welding on steel is to minimize distortion of the panel, as he does a continuous weld pass from one end to the other. Much of the distortion you see in using a Mig or Tig with filler is that each start and stop adds distortion. A non stop weld pass helps to eliminate this distortion, and keep the HAZ consistent from one end to the other..


In reading some of David Gardiner's posts, he has indicated that slight undercutting of the weld on steel was not an issue. I recently attended a metal shaping workshop (Gatormeet) and used the opportunity to attempt fusion welding on steel using the Tig. Here are my results on a piece of 18 gauge steel.

Some practice at fusion welding using the Tig, here's the front showing some slight undercutting..

The rear side shows some good weld penetration in some areas and needs more practice in others..

Just to show that slight undercutting on fusion welding was not an issue in the joint's strength, the seam was clamped in the apron brake and bent to 135 degrees, with no detriment to the weld..

 

[PCO6]

^^^ Those are good points ... and some nice welding Robert.

I was also taught that a reason for fusion welding is so that it is easier to run the welded panel through an English wheel. Welding with filler rod introduces a harder steel at the joint and it's nearly impossible to planish the weld. It can also damage the wheels.

That's a good deal and a good idea to make sturdier frames. Let us know when you're done. I'd like to see the final product!

I re-designed this, did all the cutting and grinding. The welding was done by pros.

Had to make the dog a hate because I was tired of climbing the stupid dog gate. First time making something not auto/tool related and decided not to use a bender and do it by hand for the challenge....

Got bored and decided to make a luggage rack for my harley...should be done tomorrow

I can't wait to learn to tig...projects will be so much cleaner!

Nice gate! Jump into that tig, it's another level. You'll love it.

As someone that has done custom exhaust before, I'm far more impressed by the layout/fit up than the actual welding. Fantastic job on both, you have some serious skills.
