Abstract
Current level of development of technologies for treatment of metallic materials is impossible without using of lasers, which have found application in such processes as cutting, heat treatment, welding, engraving and brazing. This paper describes investigation of process of production of stainless steel-brass bimetal joint using laser welding with full penetration. The specimens were welded on equipment of IPG «IRE-Polus» Ltd. This company manufactures machines for laser welding using tongs. Thickness of specimens from 12Kh18N10T steel and L63 brass made 3 mm. Welding was carried out at different modes, and influence of postweld heat treatment on mechanical properties of the joints was evaluated. Performed are metallographic investigations, and microhardness of different zones of welded joint is measured. It is determined that application of laser welding with full penetration for production of bimetal joints is possible under condition of more accurate adjustment of welding modes and postweld heat treatment. 8 Ref., 2 Tables, 6 Figures.
