Prediction of weld crack susceptibility

Book ·
OSTI ID:6456325
Researchers used a small-scale high-restraint cracking test to examine the susceptibility of six different high-strength low-alloy (HSLA) pipeline steels to hydrogen-induced cracking. The weld metal of HSLA steels proved to be more susceptible to hydrogen cracking than the heat-affected zone. The cracking behavior is apparently influenced by the chemical composition of the weld, the hydrogen content of the weld, the reaction stresses across the joint, and any local stresses due to weld eccentricity.
