CSA W47.1:19 Certification of companies for fusion welding of steel CSA W47.1:19 Certification of companies for fusion welding of steel 1 Scope 11 This Standard provides the requirements for the certification of companies engaged in the fusion welding of steel and the qualification of their personnel and welding procedures. Note: This Standard is not intended for applications governed by codes such as the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code and codes of the American Petroleum Institute (API). 1.2 The requirements of this Standard are based on the principle that a certified company has full responsibility for the quality of the welded product it produces and this responsibility cannot be transferred to its employed or retained personnel, or to the administrator of this Standard. 13 This Standard governs the certification of companies. Certification pertains to the capability of the company with respect to welding. Certification should not be construed as approving any products or services of the certified company. 14 This a) b) c) d) Standard stipulates requirements for welding engineers; welding supervisors; tack welders, welders, and welding operators; and documentation. 1.5 The qualification requirements for tack welders, welders, and welding operators specified in this Standard are intended to demonstrate an individual’s basic welding skills and to provide a means of verifying that individual’s continuing ability in the fusion welding of steel. 1.6 Provisions for recognition of personnel qualified under other jurisdictions are included in this Standard. 1.7 For welding of stainless steel, Annex K of this Standard specifies provisions for the qualification of welding procedures and personnel.

Class — a category of welder qualification, e.g., the flat (F), horizontal (H), vertical (V), or overhead (0) welding positions. Classification — T, S, FW, ASW, or WT welding personnel as follows: a) “T” refers to a welder’s and welding operator’s ability to weld from one side without backing and achieve complete penetration in the root pass, e.g., hollow section, pipe, and plate. b) “S” refers to a welder’s and welding operator’s ability to weld plates and rolled or hollow sections for the full thickness of material, when welding from both sides with back gouging, or when welding from one side with backing, or for welding square groove welds from both sides, without backgouging, within the thickness limitations of the accepted welding procedure data sheets for the process used. Note: Welders and welding operators holding S classification qualification can also be considered qualified to weld PJP, plug, and slot welds within the same range of performance variables. c) d) “FW” refers to a welder’s and welding operator’s ability to deposit fillet welds and tack welds. “WT” refers to a welder’s ability to deposit tack welds. CWB — Canadian Welding Bureau, a Division of CWB Group — Industry services. Essential variables — the welding parameters and other data identified in Tables11 and 12 and Clause 11.4.3 that, when changed beyond the limits specified, necessitate requalification of the welding procedures (see Clause 11.2). Group designation — the numerical system used to identify the shielded metal arc welding (SMAW) electrode classification (e.g., F1, F2, F3, and F4). Identification — the method of establishing or indicating materials, parts and consumables, and personnel used for fabrication of the product.
