PROBLEM TO BE SOLVED: To provide a heating mold for welding a plastic molding which is heated uniformly at a heating temperature over the entire mold, does not consume waste energy, and can increase temperature quickly and a method for welding the plastic molding by using the method. SOLUTION: When welding parts formed in the two or more plastic moldings respectively are heated/softened to be welded, the current-carrying heating elements of the heating mold for welding which are formed by protruding the heating elements having contact surfaces in a shape corresponding to the welding parts are energized in advance into a heating state, the heating elements are contacted with the welding parts, pressurized, heated/melted, and compressed/deformed, and the welding parts of the plastic moldings facing each other are contacted with each other and pressed until they are cooled/fixed. |
