When purchasing a stainless steel laser welding machine, it is necessary to understand these factors that affect its welding quality!

2019-10-21

Laser welding actually utilizes electrical energy converted into light energy, which is then transformed into the internal energy of the workpiece material to achieve melting or vaporization of the material, thereby achieving a permanent connection of materials. The principle seems simple, but it conceals many new technologies. In recent years, almost all electronic products require welding, and the demand for laser welding has rapidly developed due to the advancement of electronic technology and market competition. For example: televisions, mobile phones, digital cameras, and other electronic components. It can be said that laser welding machines and joint welding technology have penetrated various fields of the manufacturing industry, benefiting manufacturers by enhancing the market competitiveness of product technology, reducing production costs, improving production efficiency, and ensuring high-quality consistency in product welding.

1. Important factors affecting laser welding quality:
1. Selection of laser welding materials;
2. Selection of the quality of the laser welding machine; other important components include the type of laser. Currently, there are many types of lasers used in laser welding, classified by different properties and characteristics, so how to choose the type of laser is also something users need to consider. For example: fiber lasers, YAG lasers, semiconductor lasers, ultraviolet lasers, green lasers. From other classifications, there are single-mode lasers, dual-mode lasers, QCW lasers, CW lasers, MOPA lasers, etc.
3. Selection of the welding workbench. Due to budget constraints and different welding work requirements, users have diverse choices for workbenches. Users with sufficient budgets may prefer automation, with more complete supporting sensors and various auxiliary systems, making the welding effect more advantageous than manual or semi-automatic workbenches. However, these require analysis of actual needs to better choose the supporting equipment.
4. Characteristics of materials. Since each material has a different absorption rate for laser, generally speaking, the more conductive the material, the lower the absorption rate for laser. Therefore, materials like copper and aluminum are relatively difficult to weld, which will inevitably affect the quality of the welding.
2. Important parameter settings affecting the welding of laser welding machines.
When welding with a laser welding machine, corresponding welding software operations are required. These welding systems require users to output parameters themselves, and there are several parameters that can directly affect the welding effect;
1. The current used by the welding machine, you can set the percentage of the current;
2. The power used by the laser welding machine can be adjusted according to a percentage, but of course, it cannot exceed 100%;
3. The pulse width used by the welding machine, which is the duration of continuous laser emission;
4. The frequency of laser welding output;
5. The spot size of the laser output. If your welding seam can be slightly larger, then you can also adjust the size of the spot, but the premise is that it needs to meet the energy and demand for welding.
Different materials and different welding speeds require appropriate parameter settings, and these can be difficult for beginners or inexperienced users to control. Therefore, when purchasing a laser welding machine, it is also necessary to find a suitable manufacturer. Only with rich experience and sufficient welding experience with your materials or products can it relate to the quality of your product's welding. It is said that each profession has its own expertise; only by finding a specialized laser welding machine manufacturer can you provide good welding solutions.
