Manhart How to determine the performance stability and welding quality of handheld laser welding machines?

To determine the performance stability and welding quality of handheld laser welding machines, the following aspects can be examined:
1、 Performance stability evaluation
1. * * Output power stability * *:
-Check if the laser power of the handheld laser welding machine is within the specified range and the error does not exceed ± 10%. Stable output power is a key factor in ensuring consistency in welding effectiveness.
-Consider the long-term stable operation capability of the equipment, understand the frequency of faults, and the response speed of after-sales service.
2. * * Beam quality and focal spot size * *:
-Observe the weld quality and welding speed of the welding sample, evaluate the beam quality and focal spot size of the laser welding machine. High quality beam and small focal spot can achieve high-precision welding effects.
-Professional equipment such as beam analyzers can be used to test the beam quality and focal spot size to ensure they are within the specified range.
3. * * Stability and reliability * *:
-Assess the stability and reliability of the equipment, including its overall structure, quality of components, and manufacturing processes. Stable and reliable equipment can reduce the frequency of failures and improve production efficiency.
-You can understand the stability and reliability of the equipment by reviewing the product’s quality certification and user evaluations.
2、 Welding quality assessment
1. * * Visual inspection of welds * *:
-By visually inspecting the appearance of the weld, observe whether the weld is flat, smooth, without cracks, pores, and other defects. The appearance quality of welds is one of the important indicators for evaluating welding quality.
2. * * Weld size measurement * *:
-Use measuring tools to measure the dimensions of welds, including weld width, height, penetration depth, etc. Evaluate the consistency and stability of weld size through comparison and analysis of measurement data.
3. * * Tensile strength test * *:
-Tensile strength is one of the important indicators for evaluating the mechanical properties of welded joints. Conduct tensile strength testing on welded joints using a tensile testing machine to understand their strength and toughness.
-Based on the test results, determine whether the welding quality meets the requirements and further analyze possible problems during the welding process.
4. Analysis of Welding Process Parameters:
-Analyze the impact of welding process parameters on welding quality, including laser power, welding speed, focal length, etc. By adjusting and optimizing process parameters, find the best welding conditions and improve welding quality.
In summary, the evaluation of the performance stability and welding quality of handheld laser welding machines requires comprehensive consideration of multiple factors. In the evaluation process, suitable evaluation methods and tools can be selected based on specific production needs and actual situations, and comprehensive testing and analysis can be conducted. Through reasonable evaluation and adjustment, the stability of equipment and welding quality can be improved to meet production needs.
