WELD CRACKLING IN SUBMARINE STEELS
Abstract
The report describes results of a research program directed to the behavior of submarine steels when welded under conditions of hindered thermal contraction. The principal objectives of the investigation have been to make quantitative or semi-quantitative assessments of procedural and compositional factors in the development of residual stresses or cracking in or near welds cooling while subjected to external restraint, the external restraining apparatus being so instrumented as to give continuous information on the magnitudes of bending moment and separating force to which the welds are subjected. A further objective has been to refine and compare different types of instrumented restraining apparatus to the end of developing the most sensitive and meaningful tests possible for evaluating and comparing materials and procedures from the standpoints of how they influence stress buildup and cracking.
