Development and application of underwater stud welding gun
For the underwater operation requirements of installation
Installation
fixation
plugging and maintenance in marine engineering
an underwater stud welding gun is designed based on short-period arc welding technology. 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.
