Problems of Underwater Welding of Higher-Strength Low Alloy Steels

The article characterizes the presently used techniques of underwater welding and the problems connected with obtaining the required properties of joints. The text also presents test results related to the weldability of higher-strength steels in underwater conditions and indicates the main R&D trends in welding technologies aimed at reducing the effect of inconvenient underwater welding conditions and improving the quality of joints made under water.
