ehhh ... a TIG weld

1/4" flat stock bracket bent to a similar radius as the 1/4" tubing (i say similar because there were some nice gaps in there

145 amps with the pedal on the floor (only have a 150 amp torch)
5/32 ceriated tungsten
Ar @ 18 CFH
8 cup ... no screen
no filler
double pass
walking the cup

you can see towards the end how the weld throat was severely diminished due to the root gap. a final pass with filler will be made.


different (bad) light


nother angle




just figured i would post them up ... not the best i have done, far from the worst

I've always had better luck with TIG if the two areas being welded together were VERY clean. Your gap had a little to do with it but, next time if you grind down to bare metal at least 1/2 inch on each side you'll have a lot better results. I would always try to go with smaller "stringer beads" and stack them on each other. This seems to be a lot stronger and cleaner. I was a pipe welder before I joined the AirForce so I've done this a few times. PM me if you need some more advise.

It takes a lot of practice.

the root pass was a smaller stringer bead with just enough weave to burn in the root ....

the metal was gound on the tube and on the bracket, i just burned in the top edge a little more than i ground down to begin with

as far as advice goes, im no expert when it comes to TIG ... i m certified in GMAW and SMAW, but have no formal training in TIG ... if you see something that i could be doing better, by all means let me know. constructive criticism is one of the best ways to learn

Affende, it might be the best you've every done (as you say), but you got great penetration on both pieces and a pretty consistent pattern all the way around. That weld isn't going anywhere bro.

i definitely trust it. its a bracket for the steering stabilizer, so it coming off would not be a good thing ...

i am going to pick up a smaller cup (#5 or so) so i can get into the small gap on the inside of the bracket just to make sure ... my biggest fear right now is a crack forming at the end of the weave where the weld throat is severely diminished ... and we all know that cracks in high stress areas lead to fun times on the highway!!

you should be able to ditch the SS and drive just fine


The best part for me over the past year of learning the welding art has been blaming myself when it doesn't work. Now I can't blame others.

I agree that welding has been my most favorite hobby to practice and I enjoy it almost as much as wheelin.
