DEVELOPMENT OF UNDERWATER WELDING TECHNIQUES

The authors developed a locally drying system underwater welding process which enables underwater welding to be conducted by forming a stable gaseous zone around the welding part only with fluid curtain. The quality of weld obtained by this process is good, being little different from that obtained in an ordinary environment on land. In this paper, results of underwater welding tests conducted as an approach to the practical application of the new welding process are described. In the tests, large model blocks of a box type structure were sunk under the water, joined and welded. Also reported in this paper are a simple underwater repairing technique, examples of application of the process to underwater steel pipe welding and underwater inspection techniques such as radiographic and ultrasonic techniques.
