Research Status on Dual-Beam Laser Welding

ZHAO Yanchun;ZHANG Peilei;GU Junjie;MicroPowers Ltd.;School of Materials Engineering,Shanghai University of Engineering Science;  
Dual-beam laser welding technology is one of the research focuses in the high-energy beam welding areas,its main aim is to solve problems during single-beam laser welding.This paper firstly proposes to use the dual-beam laser welding technology to improve the laser welding according to its disadvantages(too fast cooling rate,too high precision of assembly requirements)and makes a summary of the mechanism of dual-beam laser welding.Then paper introduces the research status on twin beam laser welding of same/dissimilar material,including different parameters(interbeam spacing,dual beam energy ratio,beam configuration),the plasma behavior of keyhole,the weld performance,welding defects and so on.
