Some of my tig welding
 

I took a quick picture of the tig weld I laid down. The project was to weld a bolt on plate to the main hoop of this roll cage. It was for my cousins S-10..

Shitty Picture! sorry

um right.

Re: Some of my tig welding
 

did you think of possibly using any filler?
im pretty sure jb weld will hold up better then that undercut fail

and is that plate aluminum?

Re: Some of my tig welding
 

Filler was used, and its mild steel.

Sweet...... :-\

Re: Some of my tig welding
 

Put up some more pics. I would like to see the whole cage or at least what you have done so far. Do you bend it all yourself? Id it prefab?

Re: Some of my tig welding
 

picture is fine enough to see what needs to be seen.
AKA those welds are so bad he wants to know if the rest of the cage is welded like that. Also if you like your cousin or hate him like a rabid crab infection.

I aint bashing, but when it comes to a safety item. Holy crap. Tigging aint like using a sharpie man. That ---- needs to be tossed.


IDK how thick that pipe is, but that can't possibly be even 1/2 strength at any point based on the poor electrode angles and massive undercut & underfill.
And your pattern is spaced too far apart. That wouldn't be a "hey your weld test instantly failed" problem - if it was filled correctly and the sides weren't cut in & washed down so bad. The way it is, that causes a weak point to be even weaker!

Your not supposed to fuse roll cages together. ???

Your going to kill somebody, take a night coarse now.

Son, you're not in any position to be critical.

Re: Some of my tig welding
 

I hope you don't charge money for work like that

Re: Some of my tig welding
 

sorry i dont know if aluminum will fuse together with steel, ive never tried it. the only reason i asked if it was al is becuase of the deep scratches on the edges. only metal that looks like that that i have cut is aluminum.

Re: Some of my tig welding
 

That's the profile of the saw teeth. The set of a saw's teeth is how much it bends outward right or left from the saw. Many types of that. Most metal saws, especially band saws use a wavy profile. It lets each tooth only partially grab the material instead of the full tooth trying to grab it. The pitch of the teeth is normally varriable too.

Re: Some of my tig welding
 

i think you need alot more practice before you go tig welding cages. you would hate to hurt someone.

Re: Some of my tig welding
 

Quoted for truth

Aluminum and steel will not fuse together and provide any sort of structural bond. Steel is Ferrous, Aluminum is Non-Ferrous, read into that before you need a firesuit for the flaming you'll recieve here

Re: Some of my tig welding
 

Well, you can but its far and away beyond anything youd find most people being able to do.
If you're NASA you can friction stir it.
You can do it with bronze
Silver solder will facilitate the weld
There are afew processes for gtaw-p & gmaw-p. If gtaw and gmaw can do it that pretty much opens the door that somewhere out there PAW and flux-core have done it as well. We had a lincon guy come in our shop at school and watched him run a T joint steel bottom alu top. Neat.
You can weld them via EXW (Bi-Metallic Explosive Welding)
Hot pressure welding
You can weld aluminized steel to aluminum provided the arc NEVER wanders to the steel. You let the puddle flow to it.
I *think* you can resistance spot weld them - dont hold me to that

The only way I know joe-blow at home could do it would be buy some bi-metallic inserts where they've already been fused together. Then you simply alternate welding their respective sides together.

But you can do it, oh yes.



Check your dates

Re: Some of my tig welding
 

I stand corrected, somewhat

Re: Some of my tig welding
 

sure can. Mazda does it on the trunk lid of the new Miata. Aluminum skin, steel frame. Welded togther.

Re: Some of my tig welding
 

I've friction welded al to steel before, but I think its really more of a glorified press fit. (This was done on a turning machine made to friction weld materials)

The point I was trying to make, was not, can you Al to Steel, but how obvious that that particular picture was not a steel pipe welded to an Al plate.

Re: Some of my tig welding
 

That wont pass.

Plus, clean your material before you work with it.

Re: Some of my tig welding
 

Its a start. Just time before its right O0

shitty picture,
quality work.
good job man!

I find its a beautiful welds
everyone is such an ass on this forum
