In recent years, a rapidly growing demand for laser brazing in the transportation industry for automotive parts joining to improve the productivity, quality of the joints and cost efficiency reasons. Due to this, laser brazing technology is extensively used in the major manufacturing companies such as Volkswagen group, General Motors Europe, BMW and Ford manufacturing groups as their openingbulk production solicitation on various parts of vehicles. Laser brazing is different from the welding processes and it will block upanopeningamongst two substrates by mixture of a filler wire on condition that by a concentrated laser beam or any other heat source. Among the all joining processes, laser brazing technique is an alternative and in effect method for welding of dissimilar metals which have large difference in their melting points. It is important to understand therelationsof these phenomena of the fillers of brazing with the substrate surfaces to obtain a high quality joints. The aim of this study is to address the contemporaryenquiriesand its progress on laser-brazing, its importance to the industrial applications and to bring more awareness to the manufacturers about the research results of this technique from various research groups to enhance the research progress and developing new things from this review report.
