Description: This lecture describes the spot welding characteristics of aluminium and its alloys, the spot welding process, the choice of process parameters, strength values, electrode life and requirements for quality assurance. General engineering background and knowledge in aluminium metallurgy and physical properties, and surface characteristics (e.g. TALAT lecture 5101) is assumed.
