Hydrogen Embrittlement Susceptibility of Gas Metal Arc Welded Joints from a High‐Strength Low‐Alloy Steel Grade S690QL
Herein, the hydrogen embrittlement (HE) susceptibility of base material and gas metal arc welds from a high‐strength low‐alloy steel grade S690QL by slow strain rate test (SSRT) with in situ hydrogen charging is investigated. To investigate the influence of welding process parameters on the HE susceptibility of welded joints, gas metal arc welds in multilayer technique with two different heat inputs are conducted. The results reveal a considerable loss of fracture elongation for all hydrogen‐charged specimens when compared with the uncharged reference conditions. If the higher heat input is chosen, the required minimum yield strength in the weld metal (WM) is not achieved. It is remarkable that this WM also revealed increased HE susceptibility as measured by the relative elongation loss, despite its higher ductility associated with the lower strength level. In combination with hydrogen measurements and fracture surface analysis, the crack propagation mechanisms and related HE mechanisms are intensively discussed.
