Is anyone projection welding underwater to avoid weld expulsion?

Is anyone projection welding underwater to avoid weld expulsion?

I am not aware of projection welds being made under water. Seam welds are frequently made with water flooding. No reason that projection welds could not have water present. I expect that someone is using water in their process. Seam welds use water mainly for cooling not necessarily for expulsion.

 Electrodes not flat and parrallel projection welding

Projection weld expulsion prevention should begin not at expulsion but at its source. Process, alignment, misalignment, bad insulation, bad/uneven projections, cylinder/force problems, bad follow up and other process problems. Address the issues listed in the following article before turning to water.

CAN A PROJECTION WELD CAUSE SPATTER OR EXPULSION?
