PURPOSE:To surely deposit a wire on base metal without influencing the wire adversely by covering melting material with a low melting point as compared with the base metal and the metal wire and the satisfactory deposing property from the upper part of these base metal and metal wire to project laser light on said melting material. CONSTITUTION:A coil lead wire 2 is inserted in a groove 5 of a commutator 3 of a commutator 1. A chip 7 is fitted in a circular hole 6 of the groove 5 to cover said lead wire 2 and then, the laser light is adjusted so that the spot light strikes the overall brass chip 7 and projected thereon. The brass chip 7 on which the laser light is projected has the lower melting point than copper and besides, receives the energy of the laser light thoroughly and melts ahead of others. The molten brass 7 covers the lead wire 2 right under the brass 7 and the lead wire 2 is deposited in the groove 5 of the commutator 3. The wire can be surely deposited on the base metal without influencing the wire adversely by this method. |
