Welding of sheet-long-straight-weld （SLSW） is a difficult point in industrial weld. It is the key how to improve the weld quality and efficiency. The car of the SLSW automatic welder is one of the emphases in design to considering the features and requests of SLSW automatic welding processes. This article applies Pro/E 3D digital modeling and mechanism kinematics simulation module to optimize the design of the automatic welding car and perform motion analysis and simulation research. It solves the irrationalities of displacement, velocity and interference in the mechanism design of the welding car and optimizes the structural design of the welding car, shortens the design cycle, reduces the design cost, improves the design reliability and introduces a practical modem design method for complex motion mechanism.
