QCW Laser Welding Machine
Product Description
Device Introduction:
The first laser QCW welding machine is mainly used in the applications of mobile shielding covers, metal mobile phone casings, metal capacitor casings, MP3, MP4 casings, hard drives, micro motors, sensors, and GPS, as well as the welding of metal casings and structural parts of consumer electronic products.
Using a high-energy beam focused on the surface of the parts to locally heat and melt the material itself to form a weld, the main characteristics of this process are non-contact welding, with no stress and deformation caused by external forces; since the heating time is only a few milliseconds, the thermal effect on the material is limited to the area of the laser focus, resulting in a very small heat-affected zone; multi-point simultaneous welding technology is usually adopted to minimize the impact of welding deformation on the performance of optoelectronic devices; the welding process is measured in milliseconds, resulting in very high production efficiency.
Device Advantages:
Laser welding mainly targets the welding of thin-walled materials and precision parts, and can achieve spot welding, continuous welding, butt welding, overlap welding, and sealing welding.
1. High aspect ratio, small weld width, small heat-affected zone, minimal deformation, and fast welding speed;
2. The weld is flat and beautiful, requiring no post-weld treatment or only simple processing steps;
3. High weld quality, no pores, can reduce and optimize the impurities in the base material, the structure can be refined after welding, and the weld strength and toughness are at least equivalent to or even exceed that of the base metal;
4. Precise control, small focus point, highly accurate positioning, non-contact long-distance welding can be performed on hard-to-reach areas, providing greater flexibility and ease of automation;
5. The laser output method is very flexible, allowing for easy energy splitting or time splitting, or both, enabling simultaneous processing with multiple beams and multi-station processing, effectively improving production efficiency;
6. The main unit and workbench are separated, economically meeting different customer needs;
7. The laser energy is distributed in a cap shape within the spot range, resulting in smooth and beautiful weld points, especially suitable for spot welding, and can achieve welding between certain dissimilar materials.
Device Field:
The main application areas include mobile shielding covers, metal mobile casings, smart wearables, hard drives, micro motors, sensors, and other related products for high-speed spot welding and continuous welding, sealing welding, as well as the welding of metal casings and structural parts of consumer electronic products such as Mobile, new energy, MP3, GPS.
