Characteristics of Some Hyperbaric Welding Processes …

Characteristics of Gas Metal Arc Welding (GMAW): GMAW has also been used for hyperbaric conditions. On surface, dip transfer welding or short arc welding technique is used to transfer metal across the arc so that it is not influenced by gravity. In dip transfer technique, the wire is allowed to enter the molten weld pools short circuiting the arc.
