I’m having problems with my welded parts after anodizing. It doesn’t happen on all of the parts the frequency is minimal, but when it does happen it is a big headache.
Does anyone have an idea what is causing the discoloration? It looks to mostly at the edge of the arc cleaning etched area.
Info 6063 Aluminum extrusion welded AC GTAW with 5356 filler using a helium argon mixed gas anodized after welding.
