Titanium (Ti) alloys are widely used in industrial manufacturing, medical treatment, vehicles, and other fields. When welded with other alloys, due to great differences in physical and chemical properties of these materials, cracks easily appear in the joint, and obtaining stable welded joints is difficult. Results show that brittle intermetallic compounds (IMCs) formed in the welding process could reduce the plasticity of the joint. This review aimed to provide a comprehensive overview of the recent progress in welding and joining of Ti alloy and light alloys and to introduce current research and application. The methods available for welding Ti alloy and light alloys included fusion welding, brazing, diffusion bonding, friction welding and reactive joining. In this study, control methods of brittle IMCs in the welding process of Ti and other alloys and various improvement measures studied at home and abroad are described.
Key words: titanium alloys / magnesium alloy / aluminum alloy / joint / intermetallic compounds
