2. Weld quality assurance - Wikipedia

   en.wikipedia.org/wiki/Weld_quality_assurance

   Inspection may be manual, conducted by an inspector using imaging equipment, or automated using machine vision. [citation needed] Since the similarity of materials between weld and workpiece, and between good and defective areas, provides little inherent contrast, the latter usually requires methods other than simple imaging.

3. 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.

4. 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.

   Welding - Electron and laser-beam welded joints - Guidance on quality level for imperfections - Part 2: Aluminium and its weldable alloys ISO 13920: Welding - General tolerances for welded constructions - Dimensions for lengths and angles - Shape and position ISO 14112: Gas welding equipment - Small kits for gas brazing and welding ISO 14175

6. Welding Procedure Specification - Wikipedia

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

   The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...

7. First article inspection - Wikipedia

   en.wikipedia.org/wiki/First_article_inspection

   First article inspection is typically a purchase order requirement of the purchaser for the supplier to complete. If the manufacturer doesn't have the in-house capability or if the purchaser requests, the first article inspection may be conducted by an approved subcontract supplier such as a dimensional inspection/metrology laboratory.

8. List of welding processes - Wikipedia

   en.wikipedia.org/wiki/List_of_welding_processes

   This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

9. Risk-based inspection - Wikipedia

   en.wikipedia.org/wiki/Risk-based_inspection

   Risk-based inspection (RBI) is an optimal maintenance business process used to examine equipment such as pressure vessels, quick-opening closure - doors, heat exchangers, and piping in industrial plants. RBI is a decision-making methodology for optimizing inspection plans.
