Application Case: " Sealing Pin Laser Welding Process Using a Tap laser welding machines "

Using a square aluminum shell two-in-one Tap laser welding machine to weld aluminum alloy involves the following steps: 

1. Preparation of Aluminum Parts: 

Clean the aluminum plates to remove dirt, including polishing, chemical cleaning, and sandblasting to eliminate surface oil and impurities. 

2. Positioning and Clamping Aluminum Parts: 

Use clamps or fixtures to ensure the metal plates are correctly aligned with no gaps at the edges. 

Adjusting Laser Parameters for Specific Aluminum Alloys: 

Adjust the laser power based on the type and thickness of the aluminum alloy, and select continuous or pulse welding modes. 

3. Welding Process: 

The laser welding process is divided into three stages: heating, melting mixing, and cooling solidification.

Heating: The laser beam heats a specific part of the aluminum components.

Melting Point: The heat melts this part and mixes the molten aluminum of the two separate components.

Solidification: The mixed molten metal forms a solid joint as it cools. 

4. Surface Treatment: 

Clean the welding area after welding, remove excess material, and apply other surface treatment techniques such as anodizing, painting, or electrophoretic coating. 

5. Pre-weld Cleaning: 

Carefully scrub the weld joint with a stiff brush in hot water or soak it in a specific solution. 

6. Choosing the Right Specification Parameters: 

Determine the welding specification parameters based on the welding characteristics of the aluminum alloy, including welding current, wire feeding speed, and welding speed. 

7. Selection of Protective Gas: 

Choose the appropriate protective gas for the mother material of different thicknesses, such as Ar100% or Ar70% + He30%. 

8. Bevel Treatment: 

For thick plate T-joints, it is required to fill the bevel plus an additional fillet weld, ensuring that the total size of the weld is not less than the plate thickness. 

9. Choice of Welding Gun Angle: 

In the direction of welding, the welding gun angle is generally controlled at around 90° to ensure adequate gas protection.

These steps outline the basic process of welding aluminum alloy, ensuring the quality of the weld and improving welding efficiency. 

These steps provide a basic framework, but specific operations may vary depending on the type, material, and design requirements of the battery. In practice, adjustments may be necessary based on the experimental objectives and equipment capabilities.
