LASER WELDING METHOD AND EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To insure that weld joining can be rapidly and appropriately performed with a simple configuration in a welding method of arranging a first member and second member of metallic sheets having approximately orthogonal main units and flange sections in such a manner that the flange sections face each other and irradiating the portions between their end surfaces with a laser beam.

SOLUTION: A first guiding section (a ball unit 12) and a second guiding section (a ball unit 22) are arranged to abut on the main units (101 and 201) of the first and second members (an upper shell 100 and a lower shell 200), and the flange sections (102 and 202) of the first and second members are held between a first clamping section (a roller member 111) and a second clamping section (a roller member 21). While the flange surfaces are being irradiated in this state with the laser beam from a laser head (31) in parallel thereto, first and second supporting members (a supporting arm 10 and a swinging arm 20) are driven along the flange sections relatively to the first and second members.
