In the USA, welder qualification is performed according to AWS D1.1, [1] ASME Section IX [2] and API 1104 [3] standards, which are also used in some other countries. Some States have their own Welder Qualifications that supersede AWS Qualifications, but most defer to AWS, ASME or API.
Specification and qualification of welding procedures for metallic materials — Qualification by adoption of a standard welding procedure ISO 15613 Specification and qualification of welding procedures for metallic materials — Qualification based on pre-production welding test
The same standard defines a Welding Procedure Qualification Record (WPQR) as "Record comprising all necessary data needed for qualification of a preliminary welding procedure specification". [6] In addition to the standard WPS qualification procedure specified in ISO 15614, the ISO 156xx series of standards provides also for alternative WPS ...
For example, AWS B1.11 explains how to visually examine welds; AWS B2.1-1-004 explains welding carbon steel of thickness range of 18 through 10 gauge with semiautomatic metal gas arc welding; and AWS C2.20/C2.20M explains metalized zinc cathodic protection systems. Some codes also describe the standards used by AWS to certify welders ...
Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).
Drawn arc studs range from a #8 to 1 1 ⁄ 4" diameter. The lengths are variable from 3/8" to 60" (for deformed bars). The lengths are variable from 3/8" to 60" (for deformed bars). Arc studs are typically loaded with an aluminium flux ball on the weld end which aids in the welding process.
The objective was that the same qualifications could be awarded in any country by using a single syllabus for each level of the training course and a harmonized system for examinations. EWF developed a comprehensive and harmonized system for training, qualification and certification of welding personnel and managed its application ever since.
