Measuring diffusible hydrogen level in a ferritic steel weld

Principal MethodRapid MethodsStandardsThe principal method for determining the diffusible hydrogen in a test sample involves allowing hydrogen to evolve by diffusion at room temperature. The hydrogen is collected over a liquid in which it will not dissolve, usually mercury. The recommended practice is to leave the sample until the volume of hydrogen collected does not increase on successive days. The hydrogen evolved, together with the test piece weight, are used to calculate a volume of diffusible hydrogen (ml at standard temperature and pressureSee more on twi-globalCopper-nickel Welding and Fabrication(steel) 4.0 Welding 8 4.1 Preparation for Welding 8 4.2 Tack Welding 8 4.3 Weld Preparations 9 4.4 Welding Consumables 9 4.5 Manual Metal Arc (MMA or SMAW) 10 4.6 Gas-shielded Tungsten Arc (TIG or GTAW) 10 4.7 Gas-shielded Metal Arc (MIG or GMAW) 11 4.8 Post-weld Treatment 12 4.9 Inspection 12 4.10 Mechanical Properties of Welds 12(pipe) Metal Joining Brazing vs Welding Lucas Milhaupt(steel) You can braze steel to copper as easily as steel to steel.
