Fig. 1 — High-strength, low-alloy steels, typically those above 70 ksi, are especially prone to hydrogen-induced cracking. Using low-hydrogen filler metals, along with implementing the appropriate pre- and/or postweld heat treatments and minimizing residual stresses in joint design, can help mitigate that risk.
