TIG outside corner joint

[Dan]

I hope you guys don t get annoyed with these photos. Im just trying to give the novice weldors a little bit of an idea of what can be done with each process.
Anyway, this one is an outside corner joint on 6" stainless steel pipe.

Please keep posting the pictures, I like seeing a work of art.

Certainly not annoyed,grateful is the word.Now I see what the big deal is about tig,beautiful work.Smooth,neatly done.I especially liked how you made the turn without stopping and restarting. I see LOTS of hours practicing here. One question is it possible to stop and reposition yourself or the work and continue without it showing? You are gonna sell a lot of tig machines for Miller with these photos. Possibly one for me too.


Thanks, Russell

You actually answered your question and don t even know it. The 6" pipe was welded up by running about a 1 1/2" long bead, then I would stop so that I could reposition it. However, I didn t just keep going with back to back welds non stop. You have to watch how hot you get stainless steel if you get it to hot for to long you can end up with what is known as Carbide precipitation which basically amounts to a weld bead that will have rust along the edges of it. So to keep this from occurring, I use the shop air in between weld beads to keep the part cooled.

Hi Dan what is that in the picture looks like a Decanter or something.
