Welding and allied processes. Determination of hydrogen content in arc weld metal Ingestion-build-134498 Note: The substance EDDS exists1 Scope This document specifies the sampling and analytical procedure for the determination of diffusible hydrogen in martensitic, bainitic, and ferritic steel weld metal arising from the welding of such steels using arc welding processes with filler material. The techniques specified in this document include collection of diffusible hydrogen via displacement of mercury or collection into a headspace filled with an inert gas such as argon. The amount
