1、W55.3-08(reaffirmed 2013)Certification of companies for resistance welding of steel and aluminumLegal Notice for StandardsCanadian Standards Association (CSA) standards are developed through a consensus standards development process approved by the Standards Council of Canada. This process brings to
2、gether volunteers representing varied viewpoints and interests to achieve consensus and develop a standard. Although CSA administers the process and establishes rules to promote fairness in achieving consensus, it does not independently test, evaluate, or verify the content of standards.Disclaimer a

28、b) alignment with CSA W47.1, including introduction of three divisions of certification; and(c) editing of the terminology to bring this Standard in line with other CSA Standards and with the terms and definitions of the American Welding Society.This Standard stipulates the minimum requirements that
29、 a company must meet and adhere to in order to obtain and maintain certification in the area of resistance welding. Certification is granted by the Canadian Welding Bureau, the administrative body of this Standard. Certification indicates that, consistent with the requirements of the division in whi
30、ch the company is certified, the company has the organization, personnel, welding procedures, equipment, and process control system required to produce satisfactory welds and welded assemblies using resistance welding processes.This Standard was prepared by the Technical Committee on Certification o
31、f Companies for the Welding of Steel and Aluminum, under the jurisdiction of the Strategic Steering Committee on Welding and Structural Metals, and has been formally approved by the Technical Committee.October 2008Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the s
32、ense allows.(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.(3) This publication was developed by consensus, which is d
33、efined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list
34、and yet not be in full agreement with all clauses of this publication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.(5) All enquiries regarding this Standard, including requests for interpretation, should be addr
35、essed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation should(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;(b) provide an explanation of circums
36、tances surrounding the actual field condition; and(c) be phrased where possible to permit a specific “yes” or “no” answer.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSAs periodical Info Update, which is
37、available on the CSA Web site at www.csa.ca. Canadian Standards AssociationCertification of companies forresistance welding of steel and aluminumOctober 2008 1W55.3-08Certification of companies for resistance welding of steel and aluminum1Scope1.1This Standard specifies requirements for the certific
38、ation of companies engaged in resistance welding of steel and aluminum.1.2This Standard specifies requirements for(a)the qualification of personnel;(b) the qualification of welding procedures; and(c) process control procedures.1.3This Standard does not address safety issues associated with welding a
39、nd welding practices. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.Note: CAN/CSA-W117.2 addresses safety in welding.1.4In CSA Standards, “shall” is used to express a r
40、equirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can”
41、 is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the tabl
42、e or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.2 Reference publicationsThis Standard refers to the following publications, and where such reference is made, it shall be to the edition listed belo
