Handheld Fiber Laser Welding Machine

Handheld fiber laser welding machine is a new generation of laser welding equipment, non-contact welding, no pressure is required during the welding process, so the welded material is almost not deformed. Stable quality, reliable performance, low energy consumption, simple operation, no training required. Laser spot welding, broken welding, continuous welding and other welding forms can be realized. The welding effect is smooth and beautiful. The automatic wire filling system does not require secondary grinding after welding. It has strong adaptability to various working conditions and is basically not limited by the processing format.

Features of handheld fiber laser welding machine

1. The operation is flexible and simple, and it can satisfy multi-angle and multi-position welding.

2. Equipped with 10m original optical fiber cable, it is very flexible and convenient for outdoor welding and long-distance welding.

3. Use infrared positioning to verify the position of the welding head and verify the position during the welding process. The welding position is more accurate, the weld seam is smooth and beautiful, easy to grind and polish, and no post-welding treatment or only simple treatment is required.

4. 30-degree micro-welding without dead angle, small spot, high power density, high positioning accuracy after laser beam focusing, can be used for assembly and welding of small and micro-sized workpieces, and realize automatic mass production.

5. Laser welding has deep depth, firm weld seam, small width, small heat-affected zone, small deformation and fast welding speed. Complicated welding between some dissimilar materials can be achieved.

6. The weld seam has high quality and no porosity, which can reduce and optimize the impurities in the base metal, and can refine the structure after welding. The strength of the weld is at least equal to or even higher than that of the base metal.

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.

Handheld fiber laser welding machine safety features

ST-FW1500H/2000H/3000H is a Class IV laser system and routine precautions are required for the safe operation of the equipment.

Built-in features include:

● Key switch control of laser source and Emergency-stop button ensure deliberate operation.

● Fiber laser interlock verifies integrity of laser delivery to the welding gun.

● Laser weld gun trigger, enable and then fire, for intentional operation.

● Part contact electrical interlock turns off the laser power if the welding head is not in contact with the welded parts.

Operators must wear all recommended personal protective equipment (PPE), including laser safety glasses, laser and heat resistant gloves, hats, leather aprons, etc., and other laser and heat resistant clothing.


Compared to traditional welding

● Easy to operate, the average person can get started in half an hour, the cost of employing people is low.

● Fast, 5-10 times faster than traditional TIG welding, saving 3-5 welders.

● Concentrated energy, small thermal deformation effect.

● Fine and beautiful weld seam, no need for secondary grinding after welding.

● Deep melt pool, high strength, can weld very thin materials, can fill wire welding, can also be welded without wire.
