Abstract
PURPOSE:To prevent the thermal effect due to excessive temperature rise, by making uniform the temperature rise of the weld line, through the variable laser beam radiation energy according to the degree of thermal diffusion, in laser welding of the weld line different in the thermal diffusion degree. CONSTITUTION:The cover 3 is made on the base board 2 for electronic parts 1, it is rotated in synchronizing with the center shaft 10, and the laser beam 12 is irradiated on the boundary of the board 2 and the cover 3. In this case, unless the visual laser beam 16 is irradiated on the projection 6, the switch 22 of the control mechanism 20 is kept open and the welding laser oscillator 11 is at low output. Accordingly, the temperature rise at the boundary other than the projection 6 is kept at suitable condition. When the welding advances and the laser beam 16 irradiates on the projection 6, the switch 22 is closed and the laser beam is increased by the increment to compensate the loss due to heat dissipation at the projection 6 and irradiated on the part theta. Thus, the temperature rise in the part theta is the same as other parts.
