RESIDUAL DUCTIVITY IN WELDED JOINTS RESERVE DE DUCTILITE DANS LES JOINTS SOUDES
The measurement of residual ductility and its interpretation for welded joints in a wide range of steels is discussed. Results permit the quantitative evaluation of fracture risk for a welded joint undergoing tensile stress and containing a fault of a given dimension. Variables taken into consideration include the types of base and feeder metals used, type of heat treatment, mechanical characterisitcs, and the welding technique employed. Arc welding with laboratory control of the amount of hydrogen diffused into the weld is emphasized. The method of interpretation is based on methods used for notch tests on full scale specimens and involves a finite element analysis through a computer program.
