"Aluminium alloys represent the second most widely used metallic alloy after steel, with a production volume of 94 million tons per year. The high specific strength of aluminium allows for significant weight reductions, nowadays highly desirable in the transportation industry to reduce carbon emissions. As this is an well-established material, many manufacturing methods for aluminium alloys have been developed and matured. Welding processes are widely used to join different types and thicknesses of aluminium alloys in various joint geometries."-- Provided by publisher.
