Underwater stud welding gun Massachusetts Institute of

A conventional stud-welding gun has been modified to allow it to be used for welding under water. The stud is contained within a water-tight enclosure formed at the end of the gun by pressing the seal at the end against the object to which the stud is to be welded. A water pump evacuates the enclosure and a stream of inert gas is provided to
