摘要： PROBLEM TO BE SOLVED: To provide a technique for improving strength of jointing resin filled in a gap and a core while restraining an eddy current in a reactor having a split core.SOLUTION: A reactor 100 disclosed in this specification comprises a core and a coil 8. The core is split into at least two partial cores 2a, 2b. At least the two partial cores 2a, 2b are opposed to each other across a gap, and end faces of the partial cores 2a, 2b faced to the gap are coated with resin 42. The coil 8 is wound around the core. Plural dot-like bumps, or linear grooves not crossing with the other grooves are formed on the end faces of the partial cores 2a, 2b. By forming the plural bumps or grooves, the resin 42 enters into the bumps or grooves, so as to improve strength of jointing the resin 42 and the end faces of the metallic partial cores 2a, 2b. Even when the bumps or grooves are conducted, a conduction face is limited to a dot-like or linear range, and therefore, an eddy current can be restrained.

摘要： PROBLEM TO BE SOLVED: To solve the problem of a defect in blow holes generated by the ionization of nitrogen in the air even in the case remote welding is performed using a laser beam having a long focus. SOLUTION: A laser beam 7 introduced from a laser oscillator 3 is emitted to the surface of the part to be welded by a scanning means 5. In this case, the laser beam 7 is branched into the first branched beam 8 and the second branched beam 9, and further, the first branched beam 8 and the second branched beam 9 are condensed on the same emitting position, and are emitted. As the penetration quantity required for welding is secured, the energy density of the laser beam passing through the atmosphere in the upper part of a molten pond 13 is reduced, so as to suppress the electrolytic dissociation of nitrogen.
