Method and apparatus for twin spots pulse laser welding |
摘要 |
A twin spots pulse laser welding apparatus is disclosed which is used for providing a defect-free weld in a butt welding gap. The welding apparatus comprises a YAG laser oscillator 6, a chopper circuit for controlling the value of the lamp current of the oscillator, a chopping controller 12, a control panel 10 and a pulse generator 11 for applying a lamp current base value Wb and a peak value Wp and a pulsating pulse to the controller, and a twin spots laser head 14 for converging a laser beam delivered from the YAG laser oscillator to two foci 20R, 20L which are distributed in x direction with a very small spacing therebetween. YAG laser beam delivered from the YAG laser oscillator 6 is guided through an optical fiber cable 9 to the laser head.
