Evaluation of Underwater Welding and Cutting Equipment Available in 1969.
Abstract
A market and users survey and comparative tests on commercially available and Navy standard underwater welding and cutting equipment were conducted to determine the most suitable presently available equipment for Navy underwater salvage operations. This investigation confirmed that low weld ductility and the inadequacy of arc-welding equipment prevent in that order general acceptance of this system for underwater construction welding. While all of the arc-oxygen underwater cutting troches available in 1969 needed improvement for effective and safe utilization in Navy underwater salvage, the comparative tests showed that any of the available production-model commercial torches would provide a slightly better torch than the present Navy standard torch. For immediate improvement in Navy underwater salvage operations it is recommended that the present Navy standard torch be replaced with a commercial torch; development of an advanced arc-oxygen underwater cutting system is recommended for medium-range improvement.
