Resistance Spot Welding of Aluminum Alloy with Reference of Mechanical Properties and Microstructure: A Review
Abstract: This paper presents review on the resistance welding of Al to Al, Al to Mg, Al to Al with steel as an interlayer with focus of mechanical properties and microstructure. Major barrier for the aluminum welding is the surface oxide layer which induces higher resistance for the welding of resistance spot welding. It results in the immediate tip wear of electrode and also gives effect on the properties of weld …
