Underwater Welding Seminar Report
Underwater welding can be classified as. 1) Wet Welding. 2) Dry Welding. In wet welding the welding is performed underwater, directly exposed to the wet environment. In dry welding, a dry chamber is created near the area to be welded and the welder does the job by staying inside the chamber. Chapter 3.

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 …
