Manhart How to ensure welding quality during the operation of a handheld laser welding machine?

In the operation of a handheld laser welding machine, to ensure welding quality, it is necessary to follow a series of operating norms and technical requirements. The following are operational suggestions based on the information in the reference article:
1、 Professional training and qualification certification
1. Operators must undergo professional training to master the working principle, operating procedures, and safety precautions of handheld laser welding machines.
After passing the training, the operator should obtain the corresponding operation qualification certificate before they can start working.
2、 Preparation before welding
1. Material preparation: Ensure that the material to be welded is clean, free of stains, oxide films, etc., so that the laser can directly act on the surface of the material and achieve good welding results.
2. Equipment inspection: Before use, conduct a comprehensive inspection of the equipment to ensure that key components such as the laser emitter and reflector are clean and undamaged, and to ensure the focusing and transmission effect of the laser beam.
3. Parameter adjustment: Based on factors such as the type and thickness of the welding material, adjust the laser power, welding speed, and focus position to achieve the best welding effect.
3、 Operating standards
1. Strictly follow the equipment manual and operating procedures for operation, and do not arbitrarily change welding parameters or engage in illegal operations.
2. Keep the equipment stable and avoid shaking or collision to avoid affecting the welding quality.
During the welding process, pay attention to observing the welding situation. If there are any abnormalities, stop the operation immediately and check the equipment status.
4、 Welding parameter optimization
1. Laser power: Select the appropriate laser power based on the thickness and type of welding material. Generally speaking, the higher the laser power, the faster the welding speed, but excessive power may lead to excessive material melting and affect welding quality.
2. Welding speed: The welding speed determines the residence time of the laser on the material. Too fast a speed may lead to unstable welding, while too slow a speed may cause the material to overheat and affect welding quality. Therefore, it is necessary to adjust the welding speed reasonably based on the thickness of the material and welding requirements.
3. Focus position: An appropriate focus position can ensure the concentration of laser energy and improve welding efficiency. Normally, the focus position should be on the surface of the material or slightly below the surface to achieve the best welding effect.
5、 Fault handling and maintenance
When the equipment malfunctions, the power should be immediately cut off and professional maintenance personnel should be notified for maintenance. Operators are not allowed to dismantle or repair equipment without authorization.
2. Regularly clean and maintain the equipment to maintain its cleanliness and integrity. Check if the fasteners of the equipment are loose, and if they are, tighten them in a timely manner.
3. Check the lubrication of the equipment, add or replace lubricating oil in a timely manner to ensure the normal operation of the equipment.
In summary, to ensure the welding quality of handheld laser welding machines, it is necessary for operators to have professional skills and qualification certification, strictly abide by operating procedures and parameter adjustment requirements, and pay attention to observing the welding situation during operation, promptly handling faults and performing maintenance. By implementing these measures, the welding quality and stability of handheld laser welding machines can be greatly improved.
