A non-penetration laser welding method of welding equipment

The present invention relates to a non-penetration laser welding apparatus comprising: a laser welding head (1), a transmission fiber (2), the laser (3), a feedback control system (6), a computer (7), an infrared temperature acquisition system (8 ), characterized in that: a laser (3) output from the laser conducted to a laser welding head (1) by an optical fiber (2), after the laser beam is focused by a welding head inside the focusing lens (4) acts on the solder material (5) welding the material surface, the infrared temperature acquisition system (8) to capture the temperature of the back line of the seam welding process, the weld penetration derived case where the material, and passes control information to the feedback control system (6), by a feedback the control system (6) of the laser (3) is controlled, real-time adjustment of the power of the laser. The present invention may be precisely controlled for industrial non-penetration welding used in the welding joints appear neither unfused burn back and would not appear practical.
