With the development of laser welding technology. Pump impeller laser welding machine technology has been achieved in automobile, shipbuilding and other industries.

Laser welding machine has high compactness in the welding process of pump impeller. During the welding process, the molten pool is constantly stirred and the gas is easy to come out. The result is a natural penetration weld with no porosity. After welding, the high cooling speed is easy to make the weld fine, and the weld strength, toughness and comprehensive performance are high. Strong welding seam, high temperature heat source and the full absorption of non-metallic components produce purification effect, reduce the content of impurities, change the inclusion size and its distribution in the molten pool, welding process without electrode or filler wire, melting zone pollution is small, so that the strength and toughness of welding seam is at least equal to or even more than the parent metal.

 Aulank WD-21W pumps have the following advantages in laser welding technology:

1. Input energy is very low, and the work part deformation caused by heat conduction is also the lowest. 

2. It can reduce the welding time of thick plate and even save the time of filling metal

3. The pump impeller is welded by laser welding machine with continuity and repeatability.

4. The series of WD-021W will be used laser welding machine narrow weld and good surface quality, beautiful appearance, high weld strength.

5. Not affected by magnetic field (arc welding and electron beam welding is easy), can accurately align the welding parts. 

6. For irregular impeller, other welding methods are difficult to achieve, but laser welding is relatively easy to achieve welding. 

7. WD-021Wpump impeller will be used laser welding machine welding is easy to realize automation, and the welding efficiency is high.
