The research and development of underwater stud welding gun is introduced from the perspectives of waterproof,electrical safety and easy operation. The water tightness test,gas supply and drainage test and underwater welding test are carried out for underwater stud welding gun. The results show that the under-water stud welding gun has good waterproof performance,safe and reliable operation,and can realize the rapid underwater welding of the stud. 螺柱焊 水下焊接 焊枪 stud welding underwater welding welding gun TG453.3 2022-03-08 3 50
