playing around with thin gauge stainless

[waggie]

trying some tigging on some scrap 24 gauge stainless steel.

using 2x2x1/8 aluminum angle, and some steel blocks as heat sink.
autogenous welds, only used filler rod when tacking.

nice work!

Looks good!

... only used filler rod when tacking.

My buddy, who is quite good with a TIG torch, does it just the opposite ! Tacks are done without rod. Fill in with.

P.S. Great way to control the heat. How did you NOT get the weld to stick to the backer 2x2 ? Copper works, but very few folks would have a scrap piece of 2x2x1/8 copper !

it looks like aluminum backer to me... which won't stick to the filler.

DUH ! Stupid me !!

the backing is Aluminum angle.

regarding the filler rod: I touch the filler (.045) rod at the open corner, then start my arc on right at the rod then move the arc to the parent metal. It's more to compensate for my twitchy foot then anything.

Nice work, the straw color tell me the temperature control was just right.

Very nice for 24 ga. Good control! 24 ga. is awfully thin stuff. Ya did good!

Pretty cool, practice makes perfect.

How are you keeping the inside of the weld slag free. Is the jig hindering contamination of the weld? It seems if I linger in one spot just a little bit I get a lot of slag on the inside of the welds. Any ideas? Thanks Brian

That's what the aluminum angle is for. It does 3 things. It fixtures the pieces, It acts as a heat sink. This makes it harder to blow a hole through it. And 3, it limits exposure to oxygen from the back thus perventing oxidation.

Thanks. Good to know. Brian
