The Science Behind Laser Welding
Laser welding is a high – energy – density welding technology. It harnesses the power of laser beams, which are focused onto the joints of metal materials. Metals are generally reflective to light. However, a laser concentrates and focuses light to overcome this reflectivity. When sufficient energy from the laser beam is absorbed by the metal, it starts to liquefy. The process begins when optics, such as a curved mirror or a curved – surface lens, focus the light down to a spot size that can range from tens to a few hundred microns in diameter. This focusing creates extreme power density.
The choice of transparent optics depends on the laser type and its wavelength. For example, CO₂ lasers emit a 10.6 – micron wavelength, and standard glass is not transparent to this. Thus, CO₂ lasers use alternative lens materials like zinc selenide (ZnSe). On the other hand, 1 – micron lasers, including fiber, disk, and YAG lasers, use fused silica or glass.
Advantages of Our Laser Welding Technology
Precision
Our laser welding technology enables us to achieve a high level of precision. The ability to focus the laser beam to a very small spot size allows for intricate and accurate welds. This is particularly crucial in industries such as electronics manufacturing and medical device production, where even the slightest deviation can lead to product failure. In the production of micro – electronic components, our laser welding can create minuscule and reliable welds, ensuring the proper functioning of the devices.
High – Speed Welding
With advanced laser systems, we can perform welding at high speeds. This significantly increases production efficiency, especially for large – scale manufacturing projects. In automotive manufacturing, for instance, our laser welding technology can quickly join various parts of the vehicle body, reducing the overall production time without compromising on quality.
Small Heat – Affected Zone
Compared to traditional welding methods, laser welding produces a much smaller heat – affected zone. This means that the surrounding material experiences minimal thermal distortion. In applications where maintaining the integrity and dimensional accuracy of the base material is essential, such as in aerospace component manufacturing, our laser welding technology proves to be highly advantageous.
