First TIG welded part

[henrym]

Other than A few minutes of running beads on a small piece of .037" sheet steel and two passes over an existing weld, this is my fist GTA-Welded part.

here is the open, easy side of a lamp reflector mount:


and here is the back side, where there isn't room for the torch. i stumbled and melted the edge there, and the roughness on the left is form hot gas blowing out from behind the weld.



that is a .040", 2% lanthanum tungsten in a #4 cup, about 60 amps? no filler and no foot pedal.

That's a very nice first weld Henrym. Thanks for sharing.

Congrats!! looks very nice.

Good job! I'd be ecstatic if my first tig welds looked like that

[henrym]

thanks. hopefully I can make a ventilation/fume extraction fan and a gas cylinder cart before I run out of gas...

really, I find TIG easier than stick so far. in any position I have tried, tig is really controllable. I think stick can be hard to get a proper weld. but then again, I have only welded steel 1/8" and thinner.

Yeah, you might be thinking differently when you get up to the 1/4"+. I've heard people in the manufacturing plant where I work say that they avoid tig when welding ~1/4" or above. Then again, they also have some nice mig set ups.

You have servere undercut in those welds

and there is no filler. that is a solid shaft welded to a 0.037" (-?) bit of steel you goof.

ALl the more reason to use filler. If you use filler then you cool the weld a little and then you dont have undercut and it will be easier to weld.
