Laser welding has the following significant advantages over traditional welding:

1. High-precision and high-quality welding

It can achieve minimal weld width and high-precision welding position control, higher quality welded joints, more beautiful welds, and more reliable welding strength.

2. Smaller heat-affected zone

The heat generated by laser welding is concentrated, less heat is input to the workpiece, and the thermal impact on the surrounding materials is small,

 thereby reducing the deformation and residual stress of the workpiece.

3. High welding speed

The welding process can be completed quickly, greatly improving production efficiency, especially suitable for large-scale production.

4. Welding of difficult-to-weld materials

It can weld some materials that are difficult to handle with traditional welding methods, such as high melting point metals, dissimilar metals, etc.

5. Non-contact welding

The laser beam does not directly contact the workpiece, does not generate mechanical pressure on the workpiece, and avoids damage and contamination of the workpiece caused by contact.

6. Strong flexibility and adaptability

Welds of different shapes, sizes, and positions can be easily adapted by adjusting the laser parameters and optical system.

7. Easy to automate

It works well with robots and automation systems to achieve highly automated welding production.

For example, in automobile manufacturing, laser welding is used to connect the body structure.

 Its high precision and speed ensure the strength and appearance quality of the body, while the smaller heat-affected zone reduces the deformation of the body.

 In the electronics industry, laser welding can finely weld tiny electronic components, while traditional welding may damage these sensitive components. 

In general, laser welding has shown better performance and advantages than conventional welding in many application scenarios.
