Research Progress of Fusion Welding Techniques for Steel to Other Metals

Welding of dissimilar steel and TiNi shape memory alloys, aluminum alloy, magnesium alloy other metals is an important issue because its increasing applications in industries. This review aimed to provide a comprehensive overview the recent progress welding joining heterogeneous introduce current research application. However, base materials on both sides traditional fusion must melt large melting point difference between two seriously affects weld formation. The metal compounds formed by also hinder improvement mechanical properties joint. methods available for included welding, brazing, diffusion bonding, friction reactive joining. state understanding development method was addressed. focused fundamental microstructural characteristics, processing property relationships joints.
