GB/T 3965-2012
ActiveDetermination of diffusible hydrogen in deposited metal
熔敷金属中扩散氢测定方法
Application Summary AI generated
This standard specifies the method for measuring the amount of diffusible hydrogen in deposited weld metal, using either gas chromatography or the glycerin displacement method. It is applied in the welding industry to evaluate the hydrogen content of covered electrodes, solid wires, and flux-cored wires, which is critical for controlling hydrogen-induced cracking in high-strength steel welds. The standard is used during welding procedure qualification, consumable testing, and quality control in manufacturing sectors such as shipbuilding, pressure vessels, and structural steel fabrication.
