<p><P>PROBLEM TO BE SOLVED: To uniformly weld resin molded bodies to each other with high precision even when heat capacities of the resin molded bodies are not uniform. <P>SOLUTION: Iron powder F formed of powder bodies of 0.1-500μm is glass-coated with a glass film of 0.01-10μm, the glass-coated iron powder F is dispersed by putting resin binder of 0.1-50 wt.% with respect to a total amount, and is compression-molded to obtain a resistance value 1-10<SP POS="POST">3</SP>Ωcm and specific gravity 6-8, and is arranged between a plurality of synthetic resin molded bodies mutually. The plurality of synthetic resin molded bodies are molten and welded to each other by induction heating with a microwave. Therefore, as the iron powder F is glass-coated, heat generation efficiency of the iron powder F is improved, and electric discharge generation conditions between the iron powder F are limited because of insulation of the iron powder F by the glass coating to reduce a discharge frequency. In addition, the glass coating improves a heat insulation condition of the iron powder F to enable welding with less energy loss. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
