Other AbstractTailored laser welding is defined as two or more steel sheets with same or different thicknesses,mechanical properties or surface coatings welded together by laser before stamping,which is an important manufacturing process for automobile industry. The pressing mechanism is a critical mechanism to guarantee the positioning accuracy and the stability of the welding process. At present,mechanical pressing method is the common method in tailored laser welding,the uniform pressing plates are used in this method,and the pressing force distribution is not uniform,and the deformations of steel sheets are large,surface indentations are clear. So,the adsorption properties of the electromagnetic force on sheet sheets are Studied,electromagnetic and mechanical composite pressing mechanism is designed,this mechanism is compact,pressing force is uniform,the response is rapid,and steel sheets deformations are small.
