Can you stich weld EGT bungs to header tubes using a Mig? I know TIG is the best way, But I have not started practicing with mine and don't want to ruin an expensive set of headers..


Thanks

Ok. I asked because I was reading that Mig would make the metal brittle and crack. Thats why I was thinking stitch welding them in would prevent that.

I didn’t really stitch it per say ┬álike a body panel. After the initial tack welds. I just burned it in with 2-3 short beads. Just be confident in your welder settings are not too hot. ┬áThese were O2 bungs in the collector. Worked great. They’ve been in use for several years with no issues. I did it this way to be sure there was no pin holes to let air in and skew the readings.
