Features of laser welding mold

1. Use infrared positioning for welding position calibration and position verification during welding. The welding position is more accurate, and the welding seam is more beautiful.

2. Equipped with 10 meters of imported optical fiber, it overcomes the limitation of workbench space and can realize outdoor welding and long-distance welding.

3. Equipped with high-precision wire feeder, equipped with touch capacitive screen, 220V drive, automatic wire feeding, more powerful wire feeding, no wire jamming.

4. Self-developed hand-held welding head with various safety alarm devices, light and delicate, easy to operate, and can realize welding at any angle.

5. There are a variety of welding copper nozzles to choose from, which are suitable for various needs such as external welding, internal welding, right-angle welding, narrow edge welding, and large spot welding. Different welded copper nozzles are available.

6. The system can store a variety of different process parameters, which can be switched at any time through the touch screen according to processing needs, reducing the time for parameter debugging.

Details of laser welding mold

1. Laser welding head

Light weight only 0.8KG, flexible and convenient to weld any shape of metal parts, adjustable welding seam width, can carry out 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, supporting stainless steel and aluminum wire of 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm diameter.

4. Laser Source

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

5. Water Cooler

Double circulation water cooling makes the laser source and weld head cooler, temperature control sensor adopts imported brand.

6. Welding connection fiber

10 meters long fiber optic cable built-in design, effectively avoid damage to the fiber and the problems caused by moisture, greatly improving the service life of the laser device.

Advantages of laser welding mold

1. The integrated structure design of the whole machine, the equipment occupies a small space, and is equipped with large universal casters, which is easy to carry and carry.

2. The welding speed is fast and the efficiency is high, which is 5-10 times that of traditional argon arc welding, which saves labor and reduces the processing cost by about 30%.

3. Interactive human-machine interface, easy to operate, no need for professional welders, ordinary people can easily master it in half an hour.

4. It has the advantages of high anti-reflection ability, high efficiency of thin plate welding, deep penetration of thick plate without spatter, maintenance-free, wide operation and frequency modulation range, etc.

5. Emphasis on safety, non-direct radiation, low radiation, no harm to the body, only need protective glasses to filter strong light.

6. Concentrated energy, small heat-affected area, no deformation, no blackening, large welding depth, firm welding, fine and beautiful weld without bubbles, no need for grinding.

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.

Laser welding mold application
