This standard prescribes a standard weld test assem-bly, a standard method of test specimen preparation, and two standard methods of analysis for determination of diffusible hydrogen from martensitic, bainitic, and frric steel weld metals. The methods of preparation are suit-able for shielded metal arc, gas metal arc, lux cored arc,and submerged arc welding processes. Extension of the methods of preparation to other processes, such as gas tungsten arc or plasma are welding, are possible.
It is not the intent of this standard directly herein to classify arc welding electrodes, fluxes, and gases accord-ing to the hydrogen content of welds produced from them. However, it is the intent of this standard that it be used as the standard test method for classification pur-poses to be referenced in individual illr metal specifi-cations prepared by the AWS Comittee on Filler Metal and its subcommittees.
In addition to its use for electrode classification pur-poses, it is the intent of this standard that it be used for quality conformance testing of arc welding electrodes,fluxes, and gases.
