Features of 1500w fiber laser welder

1. Adopting fully closed optical path design, with the advantages of dustproof and good sealing; it can work continuously for a long time (up to 24 hours).

2. self-developed Wobble welding head, compact and lightweight, simple and flexible operation.

3. with a variety of safety alarm functions. The trigger switch will be activated only when the welding copper nozzle touches the metal and the safety clip clamps the metal plate. After the welding copper nozzle removes the workpiece, it will automatically lock the light. The safety of the machine is very high, which ensures the absolute safety of the operator when working.

4. Adopt 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, easy to grind and polish, no need for post-welding treatment or only simple treatment.

5. Equipped with multi-purpose nozzles to meet the welding, cutting, cleaning and other functions.

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 1500w fiber laser welder

1. high working efficiency: laser focus spot is small, high power density, fast welding speed, stable and reliable quality of welded products, and can realize large-volume automated welding tasks.

2. Various welding methods: such as spot welding, splicing welding, butt welding and so on. Different welding can achieve different welding effects, according to the nature of the workpiece, shape and other characteristics of the choice of the appropriate welding method.

3. good welding effect: laser welding weld small but large depth, fast melting speed, small heat-affected zone, small deformation, welded workpiece flat and beautiful, more in line with modern high-quality requirements.

4. Wide range of welding: laser welding machine can realize the precision welding of a variety of materials, especially for some difficult to weld materials, can quickly melt different types of metal materials. Not only can it weld precision zero devices, but also can weld large and shaped workpieces to meet different welding needs.

5. Flexibility: there is no limitation on the position of the weld, and it can contact the difficult-to-weld parts or localized positions, and complete accurate welding by precise positioning.

6. Long service life: the machine has low cost of use, service life of up to 100,000 hours, maintenance-free, installation-free, training-free, plug-and-play, is a very practical welding equipment.
