Here's a fabrication I did for the day job, with a good tech tip on spot welding. We had a galvanized hat section to make, any my spot welder would burn through at a minimal time setting. We needed another option. Here's the official napkin sketch drawing...


Our panel cut out in-the-flat...

Next, we had to make a clamping fixture to keep the metal panels tight together and an alignment collar for using the TIG, and a #5 cup. Due to the flange on the edges of our hat section, we needed a clamping device with a bit of reach. Looks like another c-clamp vise grip is lost to a specialized tool..

The "collar" is sized for clearance for the #5 TIG cup.


a 1/2-13 bolt was machined to form a post for our 1/8" thick copper cap



The TIG in process,
