1 The welding speed has a significant impact on the power output of a laser welding machine; welding speed is directly proportional to the power of the laser welding machine. At the same time, the quality of the weld not only depends on the quality of the laser beam but also on the characteristics of the laser beam as it passes through the focusing system—specifically, the size of the laser beam after focusing has a substantial influence on laser quality.

2 The distance between the nozzle and the workpiece, as well as the distance between the workpiece and the nozzle, also affects the power output of the laser welding machine. A short distance can impair the spreading capability of the spatter in welded products, while a long distance leads to unnecessary waste of kinetic energy; the optimal distance is 0.8 millimeters.

3 The focal position affects the precision of the welding machine, especially the focal diameter. The spot diameter should be as small as possible, as this results in a narrow gap. The spot diameter is directly proportional to the depth of focus of the focusing lens; the shallower the depth of focus, the smaller the spot diameter.

4 Auxiliary gases and gas pressure also affect the power of laser welding machines. If the thickness of these materials continues to increase or the welding speed slows down, it is necessary to appropriately reduce the gas pressure and use a low-pressure welding machine to prevent frost from forming on the edges of the weld.
