AWS D15.1/D15.1M:2019 pdf free download.Railroad Welding Specification for Cars and Locomotives.
5.2.1 Friction Stir Welding (FSW). When using FSW for fabrication purposes in the railcar industry, AWS Dl 7.31D I 7.3M, Specification for !‘riction Stir Welding of Aiwninuin for Aerospace Applications may he used as a guide for the development of procedure, welding operator, fabrication, and inspection requirements. The resolution of discrepancies between the requirements of this document and AWS D17.3/D17.3M shall be agreed upon by the customer and Fabricator’s Engineer. These differences may include, hut are not limited to, weld classes, essential variables in procedure qualification, eye examinations and period of effectiveness in welding operator qualification, calibration of welding equipment. qualifications of NDT personnel, NDT inspection requirements for each class of weld, and the acceptance criteria for each class of weld.
5.2.2 Capacitor Discharge Welding. When using capacitor discharge welding to apply thermocouples and/or insulation pins associated with post weld heat treatment, a written welding procedure is required and the welding operator shall he trained on proper use of the specified welding equipment. Welding operator training shall he documented. Neither qualification of the welding procedure, nor the performance qualification of the operator is required. Capacitor discharge welds used in this application shall be subject to the acceptance criteria for a temporary weld as specified in 17.1.
5.3 Welding Procedure Qualification
5.3.1 Welding of steels listed in Clauses 7 and 8, Tables 8.1 and .2, using SMAW. SAW, GMAW (except short circuiting transfer), and FCAW procedures conforming to the provisions of Clauses 5 through 8 shall be deemed as prequalified and are therefore approved for use without performing procedure qualification tests. Standard Welding Procedure Specifications (SWPSs) published by the AWS Committee on Welding Qualification in accordance with AWS B2. I/B 2.1 M, Specification for Welding Procedure and Peiformance Qualification, shall also be accepted. The use of Prequalified Welding Procedure Specifications (PWPSs) and Standard Welding Procedure Specifications (SWPSs) is not intended as a substitute for engineering judgment with respect to the suitability of application of these procedures to a welded assembly or weld repair.
5.3.2 Other materials or welding procedure specifications using one of the processes covered by this specification may be used, provided they are qualified by applicable tests as prescribed in Clause 10. The acceptability of qualification to other standards is the Fabricator’s Engineer’s responsibility, to be exercised based upon the specific structure, or service conditions, or both.AWS D15.1/D15.1M:2019 pdf free download.
