Second time welding tig/aluminum. Tell me what you guys think of my flat stock welding. I am still haven't got time to try the round tube yet, but what advice can you give on turning the tube, having someone turn it, or stop welding...turn it...start again...etc? Syncrowave 200, 1/16 pure tungsten-green, 3/32 5356 filler.

 

i normaly just tack the pipe in place. when i tack the tube i lay a bead about 1/2 long, stop turn the tube and tack again. i do that in three places, and then weld the rest. having two people to weld on tube isnt the most eff. and you need to work on the consistency of you beads, you need to add the filler at a rythem (sp?)

 

jason were those done on flat or vertically?

lookin pretty good for just getting that welder mang!

did some HEAVY tig'n at work today, got a new flexi-torch as well

 

I've always had issues with 1/16th tungsten above 120ish amps, and would definitely recommend 3/32 Red or Green tungsten. Also, I've found it to be helpful to sharpen your tungsten (like you were welding steel) and ball it on DC Positive (at around 60ish amps) it creates a smaller ball, and allows more gas to flow around, and overall a more stable arc.

Thanks man. I was thinking more of having someone or something turn the tube while I welded it.

Two flat and one vertically. Still trying to get confortable on the vertical position.
