Wet Welding - Wet welding is carried out directly in water using waterproof stick electrodes. Arc welds made underwater, without any precautions to protect the arc from the surrounding water, suffer because of hardness and brittleness resulting from the quenching effect of water. Further, hydrogen evolved due to dissociation of water in the arc, dissolves in the weld metal with a consequent tendency toward cracking.
