Underwater Stud Welding

Stud welding is a simple process which requires no skill of the operator. Experiments were conducted to determine whether underwater stud welding could be made. Most experiments were made with mild-steel studs 3/4 inch in diameter. Base plates used were mild steel and HY-80 steel, 1/2 and 1 inch (6.4 and 25.4 mm) thick. It was found that stud welding could be made successfully under water.
