Reasons and solutions for poor laser welding quality

Reasons for poor laser welding
Poor laser welding can be caused by various reasons, such as improper welding parameter settings, poor quality of welding materials, improper preparation of welding surfaces, and malfunction of welding equipment.

1. Improper setting of welding parameters
When the parameters such as laser power, focal length, and focal position are not set properly, unstable welding may occur, and the joint may not be firm or have cracks after welding.

2. Poor quality of welding materials
Poor quality of welding materials is also one of the reasons for poor laser welding. Moisture and oxidation of materials can lead to weak joints after welding.

3. Improper preparation of welding surface
Improper preparation of the welding surface can also lead to poor laser welding, such as impurities such as rust, grease, dust, etc. on the surface, which may result in weak joints after welding.

4. Welding equipment malfunctions
If the laser welding equipment malfunctions, such as power failure of the light source, it can lead to poor welding.

Solution to poor laser welding
After understanding the causes of poor laser welding, we will introduce several solutions below.

1. Reasonably set welding parameters
Reasonable setting of welding parameters can effectively avoid poor laser welding, and it needs to be set according to the type of material, welding requirements, etc.

2. Use high-quality welding materials
Choosing high-quality welding materials can effectively improve the quality of welding joints and reduce the occurrence of welding defects. At the same time, welding materials need to be stored in a dry and moisture-proof environment to avoid moisture, oxidation, and other situations.

3. Keep the welding surface clean
Keeping the welding surface clean and free of impurities can improve the stability of the welding joint and reduce the occurrence of welding defects. Proper cleaning and treatment of the surface is required before welding.

4. Regularly check the equipment status
Regularly checking the status of laser welding equipment can detect equipment failures, repair or replace equipment in a timely manner, and avoid the occurrence of poor laser welding.

In short, the treatment of poor laser welding requires comprehensive consideration of multiple factors and corresponding measures. During the welding process, it is necessary to pay attention to setting welding parameters reasonably, selecting high-quality welding materials, keeping the welding surface clean, and regularly checking the equipment status.
