Study of Underwater Stud Welding

The authors have developed a stud welding as one of the underwater welding methods the stud welding set for surface use as it is can be applied for underwater use but the gun must be modified to watertight and an air shroud must be added to gun in which air is fed and expells water and in addition fine porous material was set around the slots of the shroud preventing water pushed back in...
