SAE J2667:2019 pdf free.Equipment Acceptance Criteria for the Collision Repair Industry
This SAE Recommended Practice provides a minimum standard for evaluating squeeze-type resistance spot welding (STRSW) equipment and minimum weld performance criteria for two-sided automotive collision repair welding. This document contains several standardized test methods that are designed for evaluating equipment performance in a laboratory environment.
This SAE Recommended Practice provides manufacturers of STRSW equipment with minimum performance criteria for collision damage repairs. Collision repair centers and related businesses will also benefit by having a guideline for selecting STRSW equipment that meets this minimum performance criteria.
The use of STRSW in the automotive collision repair market has continued to grow. STRSW is being used in the collision repair process to help closely duplicate the appearance and function of the original production welds. The proper performance of STRSW is especially critical during a collision, as the welds play an important role in the structural integrity and energy management of the vehicle.
A resistance welding process that produces a weld at the faying surfaces of a joint by the heat obtained from resistance to the flow of welding current through the work pieces from electrodes that serve to concentrate the welding current and pressure at the weld area.
All units in this document are hard metric. Metric was purposely selected for ease of use, because metric is the standard unit of the United States, because automotive companies have converted to metric, and so that the document may be internationally usable. If necessary, conversions of units of measurement shall be performed according to ANSI/AWS A1.1 Metric Practice Guide for the Welding Industry. It is highly recommended that all measurements be made with metric instruments in the application of these test methods. If this is not possible and non-metric instruments are used, it shall be noted on all data and report sheets that non-metric instruments were used and that the values recorded or reported are conversions from non-metric measurements.SAE J2667 pdf free download.
