OPERATION CROSSROADS. WELDING
Abstract
In general, the overall performance of welded construction in target vessels subjected to the atomic bomb explosions at Bikini was very satisfactory. There were, however, enough weld failures to warrant certain conclusions as to which types of defects are to be more commonly expected in naval construction and the influence these defects have on the performance of structures and assemblies under blast and shock loading. Welding materials and equipment appear to have been unaffected by radiations emanated by the bomb. A relatively large number of failures occurred in way of geometrical discontinuities at connections in important structure. Weld quality, without question, appears to have been the most important factor in the performance of welded structure. Failures in brazed joints on submarine salt water lines indicated that more emphasis should be placed on frequent periodic requalifications of brazing operators. Cast iron ships machinery was very susceptible to fracture under shock loading. The performance of cast steel and fabricated steel machinery was very superior in this respect. (Author)
