Features of 2000w laser welding machine

1. Infrared positioning is used for weld position calibration and position verification during the welding process. The welding position is more accurate and the weld seam is more beautiful.

2. High precision touch capacitive screen wire feeder, 220V drive, automatic wire feed, more powerful wire feed, no wire jamming phenomenon.

3. Self-developed handheld welding head with various safety alarm devices, easy and flexible operation.

4. Equipped with 10m imported optical fiber, flexible and convenient, suitable for outdoor welding and long distance welding.

5. Excellent beam quality, with and its fine welding seam, can be precisely controlled, small focusing point, can be positioned with high precision, easy to realize automation.

6. A variety of welding brass nozzles are available for various needs such as external welding, internal welding, right angle welding, narrow edge welding and large spot welding. Different welding copper nozzles can be selected.

Details of 2000w laser welding machine

1. Laser welding head

Light weight only 0.8KG, flexible and convenient to weld any shape of metal parts, adjustable welding seam width, can be 10 meters long distance welding. Equipped with safety temperature monitoring system.

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 2000w laser welding machine

1. Flexible and simple operation, no technical threshold requirements, general workers can be on the job after a short training, can meet the multi-angle, multi-position welding.

2. Smooth and beautiful weld seam, no secondary grinding or less subsequent grinding after welding.

3. A variety of welding processes, can be spot welding, seam welding, stack welding, flat welding, internal angle welding, external angle welding, ring welding, back welding, etc.

4. Adjustable work position at any time, no need to fix the work position, free and flexible, suitable for a variety of work environment scenarios of welding.

5. Low cost of use, electricity consumption, gas consumption, lenses, etc. are low-cost consumption.

6. Small welding influence area, will not lead to deformation, blackening, and large welding depth, solid welding, melting sufficient.

2000w 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.

Available options

● Metal cutting function

Simple cutting can be done, welding and cutting can be switched freely, just change the welding copper nozzle to cutting copper nozzle, very convenient.

● Surface cleaning function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized to effectively remove rust spots, oxidation layer, oil stains, etc. from the material surface without damaging the surface characteristics.
