This is the seventh edition of CSA W47.1, Certification of companies for fusion welding of steel. It supersedes the previous editions published in 2009, 2003, 1992, 1983, 1973, 1947 (as W47), and 1938 (as a preliminary Standard). Technological advancements have made it necessary to provide an updated version.
This Standard deals with the certification of companies for fusion welding of steel. It is not a product Standard and cannot be used to evaluate or approve products. Furthermore, it is not intended to supersede Codes and Standards that govern specific products, e.g., CSA B51, the ASME Boiler and Pressure Vessel Code, the Rules of the American Bureau of Shipping, or the Standards of the American Petroleum Institute.
This Standard stipulates minimum requirements that a company must meet and adhere to in order to obtain and maintain certification. Certification is granted by the Canadian Welding Bureau, the administrative body for this Standard, to companies that comply with the requirements of this Standard. Certification of a company indicates that, consistent with the requirements of the Division in which the company is certified, it has the organization, personnel, welding procedures, and equipment required to produce satisfactory welds and weldments.
Production of satisfactory welds and weldments is the responsibility of the certified company. It is the responsibility of the purchaser to ensure, through adequate inspection, that the required quality is attained. Although the Canadian Welding Bureau (CWB) makes periodic inspections of certified companies to ensure that they continue to comply with the requirements of this Standard, these inspections do not eliminate the need for a certified company’s quality control methods or a purchaser’s comprehensive inspection program.
