Utility of the M.I.T. (Massachusetts Institute of Technology) Underwater Stud Welding Gun.

Abstract

A study was undertaken to determine tasks which could reasonably be undertaken by the M.I.T. underwater stud welding gun. During the study it wa determined that many tasks either would require special apparatus, or the use of such apparatus would greatly reduce the completed of the tasks, thereby reducing the required time as well as increasing the quality of the tasks performed. Lifting and turning padeye mounting, A-frame mounting, patching, marking, zinc replacement, hot tap mounting, shoring, cofferdam construction, jacking gear attachment, air lock attachment and space welding are the tasks that have been defined. Special templates, gaskets, gasket/templates, manipulator configurations, and pre-packaged stud welding 'boxes' were designed to accommodate the defined tasks. In order to appraise the utility of the underwater stud welding gun, special tasks and a means by which to evaluate the quality of the tasks performed have been selected. The author has hypothesized that use of the M.I.T. underwater stud welding gun will not only reduce the time required to complete the selected tasks, but also expand the environment of task accomplishment into conditions which presently are prohibitive.
