Association of Partial Melting and Hydrogen-Assisted Cracking in Weld Heat-Affected Zone of High Strength Steel (Part 5)

Correlation between Hydrogen-assisted Cracking and Partial Melting

Abstract

Partial melting was pointed out as a main factor affecting the morphology and the distribution of dissolved globular sulfide inclusions, which have a close relation to hydrogen-assisted cracking susceptibility in HAZ. In conclusion, some metallurgical factors and mechanism in connection with hydrogenassisted cracking in weld heat-affected zone of high strength steel were summarily considered.
