Abstract
A laser fusion welding device includes a 1.9 μm laser light source, a control unit and a light spot adjusting device. The control unit is configured to control the laser light source and the light spot adjusting device to adjust a laser power density at an object to be subjected to fusion welding. The 1.9 μm laser light source has output power of 100-500 W. The control unit includes a time control unit, a power control unit and a light spot control unit. The time control unit is configured to control a turn-on time of the laser light source. The power control unit is configured to control the output power of the laser light source. The light spot control unit is configured to control the light spot adjusting device to adjust a size of a light spot at the object to be subjected to fusion welding.
