Hello. My name is Marty. Where i work we're tying to weld an extrusion to rolled piece of aluminum. Specifics as i know them:
XR Aluma feed unit.
Aluma power 350 MPA.
Rolled "can" shape: 6061 T-6, .050" thick.
extrusion: 6063 T-6, about .100" thick where welded.
3/64 4043 wire
argon @ 30 CFH.
Weld looks OK, not a lot of soot (smut?). Penetration is OK. Welder is connected to a robot, and appears to work OK, e.g. position and travel speed. The robot and welder are new to us. We have the same welder on another machine where we weld the edges of the rolled can and it seems to work OK.
See attached picture. We're getting tons of porosity. Have tried welder in synergy and non synergy mode. Extrusion is anodized, but we are sanding it off, taking care to not embed anything into the aluminum.
Don't know what else to try. Supposedly the 4043 wire should work when welding this extrusion.
Anyone with any tips please send them my way.
Thx.
Marty
