Document Type and Number:
Japanese Patent JP4537287
Kind Code:
B2
Abstract:
Electrodes 2, 3 are contact with an uppermost work W 1 and energized with electricity so as to thermally expand an electrode contact portion of the work W 1 or alternatively so as to thermally expand the electrode contact portion of the work W 1 and a heat transfer portion of an adjoining work W 2 to which heat is transferred from the electrode contact portion, and then the portions are contracted so as to form a deformed portion Q and the deformed portion Q is separated from the adjoining works W 1, W 2 and a gap H is formed between the works W 1, W 2 which are overlapped, and a laser beam L is irradiated at a position where the gap H is large enough to spread the vapor generated by the vaporization of the coating heated.
