The invention relates to a diamond resin wheel and a mold and a method for machining the resin wheel. The resin wheel comprises a base body and abrasive material layers, wherein the abrasive layers are at least two abrasive layers which are fixed on the surface or the outer circle of a base body through extrusion and hot pressing, and each abrasive layer is formed by mixing and pressing differentcoarse and thin diamond particles and a binding agent; and the bonding position of the abrasive material layers and the base body are adopted with a dovetail-type structure, and the bonding faces arefurther processed into rough surfaces; the mold comprises a positioning base, a mold frame and a center mold, wherein the inner wall of the mold frame and the bottom face of the center mold form a placement area of the diamond resin wheel base body, a gap for installing a pressure head is arranged between the inner wall of the mold frame and the outer wall of the center mold, and the center mold is assembled with an assembling rod in a fixed mode through a fastening nut to be limited; the method for machining the resin wheel comprises the following steps that 1) the resin wheel base body is prepared; 2) the base body is fixed; 3) the abrasive material layers are pressed in advance; 4) hot-pressing forming is carried out; and 5) shaping and manufacturing are carried out. According to the method, a specially designed mold and a machining mode are adopted, so that the resin wheel with multiple utilization can be produced, and the grinding efficiency is improved.

The invention discloses a hybrid welding method and hybrid welding equipment for laser electromagnetic pulse. The method can be used for laser seam welding and laser spot welding technology, a pulsed high magnetic field is applied to a welding region during the process of laser welding on a workpiece with the effect of laser beams so as to mutually react with an induced plasma, a welding pool and a stress strain field through welding and complete welding task. The equipment comprises a laser device, an electromagnetic pulse generator, a numerical control system, an optical transmission system and a laser electromagnetic pulse combined machining head. The combined machining head is used for integrating the laser beams with the pulsed high magnetic field and adjusting the distance between an electromagnetic conversion device and the workpiece; the combined machining head is arranged on a machine tool. The structural deformation can be reduced, the welding quality and machining efficiency are improved, and insurmountable technical problems when a metallic material structure is manufactured through existing single welding technology are solved.
