2. Weld quality assurance - Wikipedia

   en.wikipedia.org/wiki/Weld_quality_assurance

   Inline coherent imaging (ICI) is a recently developed interferometric technique based on optical coherence tomography [8] that is used for quality assurance of keyhole laser beam welding, a welding method that is gaining popularity in a variety of industries. ICI aims a low-powered broadband light source through the same optical path as the ...

3. 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]

4. List of metalworking occupations - Wikipedia

   Weld quality assurance staff, ensuring the quality of weldments. Weld inspectors require training in metallurgy that ranges anywhere from an undergraduate familiarity all the way up to, in some cases, that of a university materials science academic. This is in addition to learning about the many types of welding equipment and techniques that ...

5. Welder certification - Wikipedia

   en.wikipedia.org/wiki/Welder_certification

   In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.

6. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   The cost of materials includes the cost of the base and filler material, and the cost of shielding gases. Finally, energy cost depends on arc time and welding power demand. [71] For manual welding methods, labor costs generally make up the vast majority of the total cost. As a result, many cost-saving measures are focused on minimizing ...

7. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   Gas tungsten arc welding (GTAW), or tungsten/inert-gas (TIG) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it ...
