On this new project I have been working on getting some .109wall 304SS tube welded up for a manifold. I am getting full penetration but seem to be having a problem with the weld appearance and need some input.
I am using a syncrowave 200 for this project and have tried both 308 and 309 filler. I have also adjusted the gas flow between 10-20 cfm and have a back purge setup at around 5cfm after flooding. Also have tried both 1/16" and 3/32" tungstens and the same on filler.
I have links below for the tube and two pictures of what the welds look like.
Any guidance would be greatly appreciated.
