| description | The invention relates to a laser splicing welding method for a galvanized steel sheet. The laser splicing welding method is characterized by comprising the following steps: step 1, base metal is provided and located; step 2, a laser welding system is provided; step 3, the laser welding system is started up, a protective gas sprayer nozzle blows a protective gas, and a laser beam transmitted by a laser welding head is perpendicularly irradiated onto the upper surface of a workpiece; step 5, a temperature sensor acquires the temperature of the back side of the base metal in real time, and the laser welding head and a high-pressure gas column nozzle are rotated when the acquired temperature reaches or exceeds the gasification temperature value of the base metal to ensure that the laser welding head is inclined relative to the upper surface of the workpiece and the high-pressure gas column nozzle is perpendicularly aligned with the upper surface of the workpiece; step 6, a gas supply valve of the high-pressure ga |
