UNDERWATER WELDING OF LOW-CARBON AND HIGH-STRENGTH (HY-80) STEEL

This paper covers two subjects, the first being multipass welding of low-carbon steel, and the second, a feasibility study of underwater welding of HY-80, a quenched-and-tempered steel with a minimum yield strength of 80,000 psi. Shielded metal-arc process was used for welding these metals. An experimental study was made of properties of multipass underwater weldments of low-carbon steel. A study also was made into the feasibility of welding HY-80 steel underwater. Lap and tee joints were fabricated, and tests were conducted to determine joint strength, ductility, and overall weld quality.
