The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
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 ]
GOST R, or Russian certification system, is a subset of GOST standards that is valid only in the territory of the Russian Federation, in contrast to the GOST standards, used across all CIS countries, including Russia. GOST R 1.5-2012: Standardization in Russian Federation. National Standards. Rules of structure, drafting, presentation and ...
Under these CSA standards, welder qualification testing is carried out every 2 years by the Canadian Welding Bureau to ensure ongoing competence. In Europe, the European Committee for Standardization (CEN) has adopted the ISO standards on welder qualification (ISO 9606), [ 7 ] to replace the old European EN 287 series. [ 8 ]

Safety. General Requirements; EN 518: Structural timber. Grading.
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).
