High-strength low-alloyed (HSLA) steels with yield strength≥ 690 MPa are gaining
popularity in civil engineering and construction of heavy vehicles. With increasing yield
strength, the susceptibility for degradation of the mechanical properties in the presence of
diffusible hydrogen, ie, hydrogen-assisted cracking (HAC), generally increases. HAC is a
result of the critical interaction between local microstructure, mechanical load, and hydrogen
concentration. In existing standards for welding of HSLA-steels, recommendations including …
