Manhart How to determine whether the performance of a handheld laser welding machine is stable?

To determine whether the performance of a handheld laser welding machine is stable, the following aspects can be examined:
1、 Output power stability
1. * * Power range * *: Check if the laser power of the handheld laser welding machine is within the specified range. Generally, the laser power range of the handheld laser welding machine is between 100W and 500W. The stability of laser power directly affects the welding effect and equipment performance.
2. * * Error range * *: The output power of the handheld laser welding machine should meet the design requirements, and the error should not exceed ± 10%. This can be determined by using a power meter to test the output power of a handheld laser welding machine and recording the error value.
2、 Beam quality and focal spot size
1. * * Beam Quality * *: Beam quality refers to the quality and uniformity of the laser beam, which directly affects the quality and stability of welding. High quality light beams can provide more uniform and stable welding effects. By observing the weld quality and welding speed of the welding sample, as well as the effectiveness of cutting and drilling processes using a laser welding machine, the beam quality of the laser welding machine can be evaluated.
2. * * Spot size * *: The focal diameter is the focusing diameter of the laser beam at the welding point, usually expressed in millimeters (mm). The size of the focal spot directly affects the welding accuracy. A smaller focal spot can achieve high-precision welding results, but the welding speed may be correspondingly slowed down. By observing the welding effect or using a beam analyzer to test the beam quality of a handheld laser welding machine, and recording the size of the focal spot for judgment.
3、 Stability and reliability
1. * * Equipment Stability * *: A good laser welding machine should have stable working performance and be able to meet the needs of long-term continuous operation. Evaluate the stability of the equipment by observing its operating status, frequency of faults, and processing time.
2. * * Reliability and Durability * *: Handheld laser welding machines need to withstand various environmental and operating conditions, so their reliability and durability are also important indicators for evaluating their performance stability. You can view the quality certification and user evaluation of the product to understand the reliability and durability of the equipment.
4、 Convenience of operation and human-machine interaction
1. * * Operation interface * *: A simple and easy-to-use operation interface can improve operation efficiency and reduce operation difficulty. Therefore, when evaluating the performance stability of handheld laser welding machines, it is also necessary to consider whether the design of their operating interface is reasonable and user-friendly.
2. * * Operation Process * *: A user-friendly operation process can make it easier for operators to get started and reduce the occurrence of misoperations. Therefore, when evaluating the performance stability of handheld laser welding machines, it is also necessary to consider the rationality of their operating procedures.
5、 After sales service and technical support
A good laser welding machine manufacturer should provide comprehensive after-sales service and technical support to solve the problems and difficulties encountered by users during use. This includes equipment maintenance, troubleshooting, technical support, and training. Therefore, when evaluating the performance stability of handheld laser welding machines, it is also necessary to consider the manufacturer’s after-sales service and technical support.
In summary, assessing the stability of the performance of handheld laser welding machines requires examination from multiple aspects, including output power stability, beam quality and focal spot size, stability and reliability, operational convenience and human-machine interaction, as well as after-sales service and technical support. By comprehensively considering these factors, the performance stability of handheld laser welding machines can be comprehensively evaluated.
