HYDROGEN-INDUCED CRACKING IN WELD METAL

The paper reviews some of the more important published literature concerning the cold cracking of weld metal in steel welds. Following a general outline of the problem, studies of the main factors contributing to the phenomenon are discussed. These are (i) the presence of hydrogen, (ii) the formation of a susceptible microstructure, and (iii) the development of welding stresses. Particular attention is directed to the work of Commission II of the IIW on the interaction of hydrogen with secondary features such as microvoids, non-metallic inclusions, dislocations, etc. and to the various test methods which have been developed for assessing susceptibility to cold cracking.
