Analysis and Design of a Novel Four-axis Plane Laser Welding System

This paper details a novel plane laser welding machine system which combines two large-scale steel blanks superposed together. Several methods are developed in order to solve the technical problems existing in plane laser welding system: It presents major-minor pressing sets which can control the deformation and eliminate the gap effectively; the design of the 4-axis machine which makes the X axis moving in small range and U axis moving in long range in the same direction can improve the precise and dynamic performance of the system. The experimental results show that this new system has potential for future industry application.
