Applications of Laser Technology in Research of Steel-Al Dissimilar Metals Welding

With the demand of lightweight vehicles becoming stronger and stronger, the joining of aluminum and steel is brought forward gradually. However, the brittle intermetallic compounds form easily during the welding process of steel and aluminum alloy, which makes it become a difficulty in the field of welding. In recent years, the laser technology has been adopted widely in the welding field of steel and aluminum alloy for its unique advantages. Authors collect some literatures through participating international cooperation, attending international conference and documents searching, and summarize the applications of laser technology in the research of steel-Al dissimilar metals welding. The purpose is to provide a reference for the researcher engaging in the joining of steel and aluminum and boost the applications of lasers in the research and production.
