Preserved Fulltext
A delayed failure test was done with notched specimens of synthetic heat-affected zone of highstrength steel. The test method was a so-called "charge and stress method, in which the specimen was subjected, at first, to a weld thermal cycle, charged with hydrogen electrolytically and then loaded in sustained manner. The main conclusions obtained in the study are as follows: (1) Root crack susceptibility of the heat-affected zone in the first layer weld of a low-alloy high-strength steel can be
