1500w Laser Welder

Hand-held fiber laser welding machine is the most widely used model on the market at present, and it is also a portable laser welding equipment. It can be flexibly applied in various environments. The limitation of welding distance is longer. It is mainly aimed at laser welding of long-distance and large workpieces. The heat-affected zone is small during welding, which will not cause deformation, blackening, and traces on the back of the workpiece.
Product Model: ST-FW1500H/ST-FW2000H/ST-FW3000H
Laser power: 1500W/2000W/3000W
Single maximum welding thickness: 0.5-8mm

Features of 1500w laser welder

1. 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.

2. Equipped with 10m imported optical fiber, it overcomes the limitation of workbench space, and can be used for outdoor welding and long-distance welding flexibly and conveniently.

3. Equipped with double protection function of water circuit and air circuit (patented technology), which effectively avoids the damage of laser lens or optical components caused by operator's misoperation, thus greatly reducing the failure rate of the machine and effectively prolonging the service life of the machine. The life of the consumables.

4. Self-developed handheld welding head, set a variety of safety alarms, easy and flexible operation.

5. The wire feeder adopts touch capacitive screen with high wire feeding accuracy. 220V drive, more powerful wire feeding, no wire jamming.

6. The laser welding depth is deep, the welding seam is firm, the width is small, the heat affected zone is small, the deformation is small, and the welding speed is fast. Complicated welding between some dissimilar materials can be achieved.

Details of 1500w laser welder

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 1500w laser welder

1. Fast welding speed, 5-10 times than the traditional argon arc welding, processing costs can be reduced by about 30%.

2. Easy to operate, no technical threshold requirements for operators, ordinary workers can be on duty after a short training, and can easily achieve high-quality welding results.

3. High weld quality, no porosity, can reduce and optimize impurities in the base material, and can refine the organization after welding. The strength of the weld, is at least equal to or even higher than the strength of the base material.

4. Good welding effect, the weld is beautiful and flat, firm, no need to polish.

5. A variety of welding methods, can achieve any angle welding: stack welding, butt welding, vertical welding, flat angle welding, internal angle welding, external angle welding, etc., can be a variety of complex welding seam of the workpiece, larger workpiece irregular shape welding.

6. easy to use and flexible, can be adjusted at any time, no need to fix the work station, free and flexible, suitable for a variety of work environment scenarios of welding.

1500w laser welder 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.
