Abstract

Welds of hydrogen transportation pipelines exhibit high hydrogen embrittlement (HE) susceptibility. To obtain the optimum welding process, the hydrogen compatibility of the 20# steel welds with different welding processes was tested by in-situ gaseous hydrogen permeation and slow strain rate tensile (SSRT) tests. The fracture surface analysis of the welds was also presented. The welding process with the best HE resistance was selected. Moreover, the mechanism between the HE susceptibility and microstructure of the welds was discussed. This study provides a reference for the selection of welding process for long-distance hydrogen pipelines.
