Seven advantages of QCW laser welding machine, six major industry applications！

Compared with traditional lamp-pumped laser welding machines, QCW laser welding machines have the characteristics of good beam quality and small divergence angle. Compared with traditional laser welding machines in high-speed and high-precision welding, the welding efficiency and weld effect have great advantages, and are widely used in optical communication devices, IT, aviation components, fuel injectors, diesel common rail systems, solenoid valves, watch fine parts, automobile headlights and other products.

Benefits of QCW laser welding machine

1. The input heat can be reduced to a lower required amount, the metallographic change range of the heat-affected zone is small, and the deformation caused by heat conduction is also low.

2. No need to use electrodes, there is no concern about electrode contamination or damage. And because it does not belong to the contact welding process, the wear and deformation of the machine can be reduced to a minimum.

3. The laser beam is easy to focus, align and guide by optical instruments. It can be placed at an appropriate distance from the workpiece, and can be guided between the machine or obstacles around the workpiece. Other welding methods cannot be used due to the above-mentioned space limitations.

4. The laser beam can be focused on a very small area, and can weld small and closely spaced parts. It can weld a wide range of materials and can also join various heterogeneous materials.

5. It is not affected by magnetic fields (arc welding and electron beam welding are easy), and can accurately align the weldment.

6. If perforated welding is used, the depth-to-width ratio of the weld can reach 10:1.

7. When welding thin materials or thin-diameter wires, it will not be as troublesome as arc welding.

QCW laser welding machine is an ideal choice for spot welding, seam welding and long pulse drilling applications. Compact structure design. Due to its electro-optical conversion efficiency of more than 30% and maintenance-free operation, the cost-effectiveness is far better than that of conventional YAG lasers. It is mainly used for welding thin-walled materials and fine parts, and can realize spot welding, butt welding, lap welding and sealing welding. Compared with ordinary hard light path laser welding machines, QCW laser welding machines have uniform energy distribution of welding spots and have better light spots required for welding characteristics. Suitable for customized special automated tooling fixtures to achieve mass production of products. Laser welding technology is an important part of industrial processing technology application. The emergence of fiber-optic transmission laser welding technology makes the technical advantages of laser welding more significant. Fiber-optic transmission laser welding machine is equipped with CCD camera monitoring system for easy observation and accurate positioning.
