Weld process for fillet welded lap joints in sheet steel
Weld process for fillet welded lap joints in sheet steel
(OP)
All,
I often have spec'd fillet welds on the edges of 0.094 and 0.125 steel sheet, such as in ring or slot welds. I have also often regretted specifying these due to the poor observed results (too much weld, distortion, burned edges)
AWS D15.1 mentions that various processes are acceptable for these types of welds.
Shouldn't these always be GTAW? Is any guidance available on this practice?

GTAW process is widely known to cause distortion. If you are set on using GTAW start trying pulse. Based on the info above, I do not see any reason GMAW or SMAW would not work here. Either process should produce less distortion.

as this doesn't melt the base metal, but gives good tensile results, it might be worth looking into?

Thanks everyone- I will use GMAW with the guidelines that Ron provided.
I'll confirm with a welding eng. buddy as well.
Out of curiosity, if our drawings typically specify "All welding to comply with AWS D1.1", doesn't that imply that sheet steel welding will be in conformance with D1.3, and by consequence, the welders will be qualified to that standard also?
