ABSTRACT:
An underwater arc stud welding system consists of a specially designed submersible stud welding gun which is connected, by means of an electrical umbilical to conventional stud welding equipment located out of the water. The stud gun employs a simple, corrosion resistant, stud lifting mechanism with only one moving part, which freely floods with water and thereby eliminates problems associated with increased ambient pressure and also employs a magnetic base and a grounded electrical safety shield.
