The diamond saw blade is fixed to a laser welding jig to use magnetism. The jig comprises; a magnetism generating section including first electromagnet supporting the lower side of a segment and imposing the downward magnetism upon the segment and a second electromagnet supporting the lower side of a steel core and imposing the downward magnetism upon the steel core; a magnet coil supplying the magnetism generating section with magnetism; a magnet supporter supporting the magnetism generating section; and a magnet coil support frame supporting the magnet coil and the magnet supporter. There is no necessity for clamping the segment and replacing the saw blade. |
