Laser Fibre Welding

Handheld laser welding is a new type of welding method, with various welding methods (spot welding, stack welding, butt welding, etc.) for welding thin-walled materials and precision parts. When using a laser welding machine, the positioning is accurate, the welding speed is fast, the welding effect is good, the weld width is small, the weld bead is smooth and beautiful, the heat affected zone is small, the deformation is small, the post-welding treatment is simple, and the work efficiency is improved.

Features of laser fibre welding


1. Flexible and easy to operate, it can meet welding and cleaning requirements from multiple angles and positions.

2. The self-developed swing welding head is compact, lightweight, and easy to operate.

3. It has multiple safety alarm functions. The switch will only be activated when the welding nozzle contacts the metal and the safety clamp clamps the metal plate. The light will automatically turn off when the welding nozzle is moved away from the workpiece. The machine has a high level of safety to ensure the absolute safety of the operator during work.

4. It uses infrared positioning to verify the position of the welding head during the welding process. The welding position is more accurate, the weld seam is smooth and beautiful, and it is easy to polish without the need for post-welding treatment or only requiring simple treatment.

5. It is versatile, equipped with multi-purpose nozzles to meet welding, cutting, cleaning, and other functions.


Details of laser fibre welding


1. Laser welding head

The light weight is only 0.8KG, flexible and convenient to weld metal parts of any shape, the weld width is adjustable, and it can perform long-distance welding with a length of 10 meters. With security monitoring system.

2. Operation interface

Advanced resistive touch screen with higher sensitivity, intelligent control, can store multiple welding parameters, support multiple languages (English, Spanish, German, Italian, French, Russian, Turkish, etc.)

3. Automatic wire feeding system

Touch screen design, automatic wire filling, fully digital design, support 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm diameter stainless steel and aluminum wires.

4. Laser source

We use a customized 45um core diameter welding fiber laser with a lifespan of 100,000 hours, maintenance-free, and can weld various metals.

5. Water chiller

Double circulating water cooling makes the laser source and welding head cool better, and the temperature control sensor adopts imported brands.

6. Solder connection fiber

The 10-meter-long fiber optic cable, built-in design, effectively avoids the damage of the fiber and the problems caused by moisture, and greatly increases the life of the laser components.

Advantages of laser fibre welding


1. The laser welding gun adopts a handheld design, which is comfortable to hold and can flexibly deal with various objects and angles.

2. The operation is simple and easy to learn, with no technical threshold for operators. Ordinary workers can start operating after a short training, and can easily achieve high-quality welding and cleaning effects.

3. The fully enclosed optical path design, self-designed based on the principles of laser optics, has a more reasonable structure, dustproof, good heat dissipation, and effectively extends the service life of machine components.

4. Suntop's patented technology water circulation protection system and auxiliary gas detection effectively extend the life of the laser lens and prevent damage to optical components caused by improper operation.

5. Infrared positioning verifies the position of the welding head during the welding process. The welding position is more accurate, the weld is smooth and beautiful, easy to polish, and no post-welding treatment is required or only simple treatment is needed.


Other optional functions of laser fibre welding


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 a non-contact feature, does not require cleaning solution, and 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.

Weld 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 seam surface clean. This not only helps improve the quality of the weld seam but also enhances its strength and appearance. Laser cleaning has high precision and controllability, allowing thorough cleaning of the weld seam surface without damaging the base material.
