How To Ensure The Stability Of Welding Quality Of Laser Welding Machine?

In the daily use of the laser welding machine, the welding quality is unstable. When processing metal welding in batches, many users will worry that the laser welding machine will be used for too long and cause unstable operation, so the quality of the processed products will be uneven, so the quality of the products should be maintained. stability is crucial! So how to use laser welding machine to maintain the stability of product quality?

How to use laser welding machine to maintain the stability of product quality:

1. The selection of a laser welding machine must first determine the processing materials, especially when welding two or more different materials, to determine whether the materials can be reliably welded. In addition, different materials have different reflectivity to different laser wavelengths. , the higher the reflectivity, the more difficult the laser welding is.

2. The laser welding effect of the laser welding machine is related to the optical properties, physical properties and mechanical properties of the processed material. Optical properties: including reflectivity, absorptivity, transmittance, etc. of materials; physical properties: including thermal conductivity, thermal diffusivity, density, specific heat, heat capacity, melt viscosity, vaporization temperature, etc.; mechanical properties: machining Accuracy, stress strength, material weldability, workpiece cleanliness, etc.

3. The physical and mechanical properties of different materials of the laser welding machine will also have a crucial impact on the welding effect. Generally speaking, during spot welding, the greater the thermal conductivity, the better the welding effect; on the contrary, during seam welding , the smaller the thermal conductivity, the better the welding effect. Users need to make reasonable choices according to different application requirements. Even if it is the same material such as aluminum, due to the difference in the purity of aluminum and the doped elements, sometimes the material type is different, the resulting welding effect is also different, even the same type of material, the incoming batch is different, the welding effect is also different. It is not the same; users need to adjust the power waveform of the laser welding machine appropriately to improve it according to different situations.

The above is the general content of how to use the laser welding machine to maintain the stability of product quality. I hope this article will be helpful to everyone.
