  2. Weld quality assurance - Wikipedia

    en.wikipedia.org/wiki/Weld_quality_assurance

    Weld monitoring methods ensure the weld's quality and correctness during welding. The term is generally applied to automated monitoring for weld-quality purposes and secondarily for process-control purposes such as vision-based robot guidance. [citation needed] Visual weld monitoring is also performed during the welding process. [citation needed]

    en.wikipedia.org/wiki/Welding_Procedure...

    Bend test coupons for welding procedure qualification. A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.

    ISO 14555 is appropriate where it is necessary to demonstrate the capability of a manufacturer to produce welded construction of a specified quality. ISO 14555 has been prepared in a comprehensive manner, with a view to its being used as a reference in contracts. The requirements contained within it can be adopted in full, or partially, if ...

  7. Engineering Critical Assessment - Wikipedia

    en.wikipedia.org/wiki/Engineering_Critical...

    Engineering Critical Assessment (ECA) is a procedure by which the safety of a welded structure with defects or flaws can be determined. ECAs utilize the material properties and expected stress history to determine a flaw acceptance criteria which will ensure that welds will not fail during the construction or service life of the welded structure. [1]

  9. Gas tungsten arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_tungsten_arc_welding

    The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing stronger, higher-quality welds. However, TIG welding is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques.
