Welding Lathe >>

Hi,
Anybody have any experience with a table top ( Do to a lack of a better word)
Welding lathe.
Also is there any sources of used ones?

THANKS

Are maybe referring to a weld positioned?

 

[dirtmister16]

do you mean a turntable or fixture jig?


it so check out keith fenner on youtube he has one and is really handy from what i can tell. maybe it will help you out.

Are you thinking of a welding positioner?

They work great, but are not cheap unless you get lucky on the used market.

No what I am looking for is very similar to a regular lathe but with a Tig or mig welding handle built in.
I want to be able to build up shafts either round de round or back and forth.
Each time it makes a pass it would have a micro switch that would kick the welding handle over to the next pass.
It would make a pass then kick over, make a pass kick over, and so on.

I wish I could use the correct words to explain.

crankshaft journal repair, used one in the early 80's to repair a folder cyl now a day they just spray weld to build it up

Bill,

What you are looking for is a submerged arc crankshaft welder. I
I have one that was built by standard crankshaft . The most popular
and best ones are from Gleason works . I also have a sub arc machine
much bigger than the crank welder for building rollers and front wheels
for crawlers, has a 600 amp welder for power unit.

Buildup with weld usually warps the shaft some , spray doesn't. Welding
around warps it some , welding lengthways will really warp it.

As ray said most shaft repair is done with metal spray , I also do
both powder and wire spray . Spray is much safer to do as it doesn't
get the shaft hot enough to change the heat treatment.

Would you mind me picking your Brain some?
I will start asking like I heard you say go ahead.
Powder Vs,wire spray what is the difference
In the words I understand 1 uses Powder and the 2nd. uses wire some how.
Are both process's machinable when done?
How do you keep the spray ( either type ) from sticking where you don't want it?
Many years ago our family had heavy Const. Equipment and from time to time there was a fellow that would come to the yard and do some sort of spray welding on the bosses for the bucket Bushings. I was much younger then and never payed much attention how the process was done.
Now He is long gone so I can't go to him with my Questions.

Thanks

wish i had some pictures of it, machine shop that i used to work in custom fabricated a submerged arc setup on an old lathe.

25" chuck, 25' bedway, natural gas burners along the length of the bedways to keep material being welded at proper temp.

lathe was regeared to turn 1 or 2 rpm, automatic wire feeder ran the most awesome 2"-3" wide bead in stainless. all the operator had to do was keep the flux hoppers full, and ride along with the carriage.

that part of the shop made conveyor rolls, and crane hoist drums for the steel mills.

most of the rolls they worked on had the bearing journals built up, and roll bodies overlayed, then rough machined, heat treated, straightened, and ground to final size.

Bill.

I have to go out for a bit ,be back around supper time . Being the

poor and slow typist that I am , send me an email with a phone #

and I'll call you later and try to explain the differences.

I operated a Storm Vulcan Crankshaft Welder in the 1970's to weld up damaged Journals. As I remember, we had 3 different types of crankshaft steel, Arma Steel, Cast Steel, and Nodgular Steel. Each one required a different flux, in the hopper, and it's own wire filler material. Once you get it set up properly, it makes a near perfect weld, and the slag rolls off like a snake shedding its skin. Normally, one pass will do the job, but you need to grind it before you will know. Is this what you seek?
