Firstly, the laser welding impeller skill is used to make up for the drawbacks of traditional electric resistance welding of water supply equipment. The line sealing rate of the front and rear cover plates of the impeller can reach 100%. The smooth and accurate flow path minimizes the loss of hydraulic flow in the flow path, ensuring the efficient operation of the pump and reducing the cost of the customer.

The impeller is both a wheel with a moving blade and an integral part of an impulsive laser welded impeller turbine rotor. Also refers to the general term for the rolling blades on the wheel and the device. Also refers to the general term for the rolling blades on the wheel and the device.

The blade shape of the centrifugal fan impeller is of single plate type, circular arc type and airfoil type, as shown in Fig. 1. The airfoil blades
