The characteristics and difficulties of medium frequency resistance RSW (MFRSW) of high strength Al alloy TL091 were analyzed. In order to improve the service life of Al. alloy RSW electrode cap (EC), the shape of EC and welding parameters were studied. The weld ability of RSW of Al. alloy TL091 was studied by using a special pressing mold to make the surface of EC form a special shape. By studying the type and size of the surface-forming mold, pressing method and pressing parameters, the key factors affecting the weld ability of Al. alloy RSW were obtained. The specification and shape of compaction mold will affect the adhesion between alloy and EC, and pit depth, pit distance width and boss size of the mold have great influence on welding ability of Al RSW after single grinding. When indentation depth of the pressing mold is 0.5 mm, the width between the molds is 0.4~0.5 mm, and the width of bulge is 0.2 mm, it can obtain a RSW capability of at least 128 points after each grinding. The direction and ideas for improving the life of Al. alloy RSW EC were determined, which could provide reference for the optimization of automobile Al. alloy RSW.

“…Due to the low melting point of the aluminum alloy material, the welding of the thermalexpansivity is high, the surface of the aluminum plate material is easy to oxidize, and it is easy to produce defects such as welding porosity and cracks in the welding process. Welding process, copper electrode and aluminum plate at high temperature, aluminum-copper metal interface is easy to generate poor conductivity AL2Cu and AL4Cu9 and other brittle intermetallic compounds [1,2], which leads to the surface of the copper electrode is prone to electrode erosion phenomenon, affecting the welding quality and welding life [3][4][5].…”

Aluminum alloy RSW is influenced by the low melting point and high thermal expansion rate of aluminum alloy materials. During the welding process, the electrode cap surface is prone to erosion, which affects the continuous welding number and welding quality of RSW. It is a difficult problem in the industry that restricts the application of aluminum RSW. This article studies the factors affecting the weldability of resistance spot welding (RSW) of aluminum alloy materials, including plate materials, electrode specifications and materials, equipment structure and welding control methods, electrode connection methods, welding process specifications, etc., and identified possible ways to enhance the weldability and weld quality of aluminum alloy spot welding. Through the experimental study, it was further explored that the comprehensive performance capability of aluminum alloy RSW can be improved by setting appropriate welding parameters for the electrode with R100mm arc at the front end for the flat aluminum plate which has been pickled and passivated.
