This Recommended Practices is a collection of data and procedures that are intended to assist the user in setting up resistance welding equipment to produce resistance welded production parts. While the recommendations included are not expected to be final procedures for every production part or every welding machine, they serve as starting points from which a user can establish acceptable welding machine settings for specific production welding applications. In some cases, recommended machine data is not available. In these instances, some description of the process is given to assist the reader in determining if the process might be suitable for the application.

AWS D1.6/D1.6M-2017: Structural Welding Code – Stainless Steel contains welding recommendations for the fabrication, assembly, and erection of welded structures and weldments subject to design stress in which at least one of the materials being joined is stainless steel. It is for use with base metals with a minimum thickness of 1/16 in (1.5 mm) or 16 gage, in conjunction with any complementary code or specification for the design or construction of stainless steel structures and weldments. In addition to background information and terms relevant to those involved with stainless steel fabrication, the AWS D1.6-2017 code includes a clause that covers guidance on the design of welded connections. Other clauses in the standard focus on exempting a Welding Procedure Specification (WPS) from qualification by testing, qualifying WPSs and welding personnel, the fabrication, assembly, and erection of welded stainless steel structures, inspection and acceptance criteria, and stud welding.
