The laser light of the welding machine will have the following effects on the welding effect:
1. **Reduced strength of welded joints**: Unstable laser light intensity will make the strength of welded joints uneven, affecting the quality and durability of welds.
2. **Uneven Weld Appearance**: Changes in light intensity cause uneven weld appearance, and areas of incomplete or excessive melting may occur.
3. **Unstable penetration depth**: Fluctuations in light intensity lead to inconsistent penetration during welding, which affects the firmness and durability of the weld.
4. **Increased welding deformation**: The unstable light intensity causes local overheating of the weldment, resulting in the aggravation of the deformation of the heat-affected zone.
5. Porosity and cracks: Unstable light intensity may produce porosity and cracks in the weld, affecting the strength of the weld.
6. **Reduced welding efficiency**: More time and energy is required to adjust and repair welding defects, reducing the overall welding efficiency.
7. **Increased rework rate**: Unstable welding quality may require multiple rework and overhaul, increasing production costs and man-hours.
In order to maintain high-quality welding, it is necessary to ensure that the laser light intensity is stable, the equipment must be regularly maintained, and the working conditions must be controlled.
