Features of laser welding galvanized steel
1. Multi-purpose, equipped with versatile nozzles to meet welding, cutting, cleaning, and other functions.
2. Independently developed handheld welding torch, equipped with various safety alarm devices, easy and flexible to operate.
3. Uses infrared positioning to verify the position of the welding torch, ensuring more accurate welding positions, smooth and beautiful welds, easy for polishing, and no need for post-welding treatment or only simple treatment.
4. The machine has multiple safety alarm functions. The welding copper nozzle's trigger switch is only effective when it touches the metal and securely clamps the metal sheet. The welding copper nozzle will automatically lock the light after moving away from the workpiece. The machine has high safety to ensure the absolute safety of operators during work.
5. Suntop's patented technology of water circulation protection system and auxiliary gas detection effectively prolongs the service life of the laser lens and prevents damage to optical components caused by improper operation.

Advantages of laser welding galvanized steel
● The new generation integrated cabinet integrates laser, chiller, software control, and other components, with advantages such as small footprint, easy mobility, and strong functionality.
● The handheld swing welding head is equipped with 5-10 meters of original fiber optic cable, providing flexibility and convenience.
● The handheld operation mode, equipped with a dedicated laser processing head, allows for welding of any part of the workpiece at any angle.
● Compatible with various laser sources, suitable for various process requirements of workpieces, achieving one-time forming with minimal deformation, meeting high-quality product requirements.
● The weld seam is aesthetically pleasing, without scars or discoloration, and does not require subsequent polishing.
● The welding is firm, and the weld seam strength reaches or even exceeds that of the base material itself.
● Suitable for butt welding, lap welding, inside and outside corner welding, arc welding, irregular shape welding, etc.
● The entire equipment has strong functionality and meets ergonomic design, suitable for various working environment scenarios.
● Exclusive laser operation protection function ensures the safety of operators during work.
● Simple and easy to learn operation, with low technical requirements for operators, resulting in reduced labor costs.
Other optional functions
● Cleaning function
By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be achieved, effectively removing rust, oxide layers, oil stains, etc. from the material surface without damaging its characteristics. It has the characteristic of non-contact and does not require cleaning solution, which can replace professional cleaning equipment.
● Cutting function
It can perform simple cutting, and welding and cutting can be freely switched by simply changing the welding copper nozzle to the cutting copper nozzle, which is very convenient.
It can cut metal sheets such as stainless steel, carbon steel, aluminum, aluminum alloy, and iron, with a maximum cutting thickness of about 2mm.
● Welding seam cleaning function
It can effectively remove impurities such as oxides, welding slag, oil stains, and dust generated during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning has high precision and controllability, and can thoroughly clean the weld surface without damaging the base material.
