Laser Handheld Welder

Handheld fiber laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. It does not need to be pressurized during the operation process. The weld seam is smooth, beautiful and firm. It does not need secondary grinding after welding, which saves labor costs. It can be easily applied in all types of environments and has a higher professional standard and reliability.

Features of laser handheld welder

1. Handheld welding head replaces the previous fixed optical path and the limitation of the travel space of the customer service table. Equipped with 10m original fiber optic cable, flexible and convenient to realize outdoor welding and long-distance welding.

2. Adopt infrared positioning for welding position calibration and position verification during welding, more accurate welding position and more beautiful determination of the weld seam.

3. The whole machine is designed with integrated structure, the equipment occupies little space, with large universal casters, easy to carry and transport.

4. Equipped with automatic wire feeder to solve the problem of large welding gap.

5. Suitable for a variety of welding processes, can weld high melting point, high strength metal materials and alloy materials, suitable for a 

variety of complex welds, welding of various devices, flexible and convenient.

6. With a variety of safety alarm functions. The trigger switch only takes effect when the welding copper nozzle touches the metal and the safety clamp clamps the metal plate. The light will be locked automatically after the welding copper nozzle moves away from the workpiece. The machine is highly safe, ensuring absolute safety for the operator while working.

2. Operation interface

Multi-language intelligent control panel, flexible adjustment of welding parameters, multi-group welding parameter library, light output cumulative timing, 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 wire.

4. Laser Source

We use customized minimum 20um core diameter fiber for deeper penetration, laser life up to 100,000 hours, maintenance-free, with Bluetooth capability.

5. Water Chiller

Double cycle water cooling makes the laser source and welding head cooling better, temperature control sensor adopts imported brand.

6. Welding connection fiber optic

10 meters long fiber optic cable with built-in design effectively avoids damage to the fiber and problems caused by moisture, which greatly increases the service life of the laser components.

Advantages of laser handheld welder

1. The requirements for operators are lowered, no training is required, and ordinary employees can operate after a short training.

2. The welding quality is good, and it can complete the welding tasks that cannot be completed by ordinary welding machines. The workpiece is not deformed, the weld seam is beautiful, there is no welding slag, and the welding depth can be reached. It can perform non-contact welding at special corner positions.

3. The efficiency is improved, which is 5-10 times that of ordinary argon arc welding, and it can be connected with tooling and robot automatic welding.

4. The maintenance cost is low, the life of the laser can reach more than 100,000 hours, the daily maintenance is basically free, energy saving and environmental protection.

5. A variety of welding nozzles are equipped as standard, such as flat-angle, inner-angle, and outer-angle nozzles. According to different welding needs, different nozzles can be replaced to meet various welding needs.
