Can you guys explain to a novice welder what is meant by " blunt, recessed tungsten"?. MIG, TIG?
I know a guy that simulates spot welds by simply turning the amperage up high enough to basically 'burn through' the top layer bonding it to the lower layer...My description, not his... Never tried it myself as all of my efforts are usually focused on trying to avoid a burn through!
