HIGH PRODUCTIVITY ONE-SIDED MIG-WELDING TECHNIQUE

To overcome embrittlement problems associated with one-sided, submerged arc welding processes, the paper recommends the use of high current, one-sided MIG-welding with large diameter filler wires for the butt joints of ships' main hulls. The technique provides nearly the same productivity as that obtained by one-sided submerged-arc welding, and at the same time gives satisfactorily high levels of notch toughness at the weld fusion boundary as well as in the heat-affected zone. The paper indicates the recommended welding conditions for various services including the high strength D/E grades and low temperature service.
