Features of continuous laser welding

1. Infrared positioning is used in the welding process for welding position calibration and position verification. The welding position is more accurate and the weld is more aesthetically pleasing.

2. Equipped with 10 meters of imported fiber, outdoor welding and long-distance welding are very flexible and convenient.

3. Adopting Suntop patented water circulation protection system and auxiliary gas detection technology, effectively prolong the service life of laser lens, and prevent optical component damage caused by improper operation.

4. Handheld welding gun, light and delicate, easy to operate, can achieve welding at any angle.

5. Standard angle, inner angle, outer angle and other welding copper nozzles are provided. According to different welding needs, different nozzles can be replaced to meet various welding requirements.

6. It can realize welding at any angle, pile welding, butt welding, vertical welding, angle welding, inner angle welding, outer angle welding, etc., and can weld various complex workpieces, and large irregular shape workpieces.

Details of continuous laser welding

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 continuous laser welding

1. Laser welding is a non-contact welding, the work process does not need to be pressurized, welding speed, high efficacy, depth, residual stress and deformation of small, can be at room temperature or special conditions (such as closed space) for welding, welding equipment device is simple, does not produce X-rays.

2. Can be welded such as high melting point metal refractory material, the shaped material welding, good results, and has great flexibility, can be difficult to access the parts of the welding non-contact long-distance welding.

3, the laser beam can be focused to obtain a very small spot, because not affected by magnetic fields and can be accurately positioned, therefore, can be micro-welding, suitable for high-volume automated production of micro, small workpiece welding.

4. Laser beam is easy to realize the beam by time and space, can switch the device will be transmitted to the laser beam lift multiple workstations, therefore, can be multi-beam simultaneous processing and multi-station processing, for more precise welding provides the conditions.

5. Laser welding does not have the problem of tool loss and tool exchange, and at the same time, it does not require the use of electrodes, so there is no concern about electrode contamination or damage, and is easy to automate the high-speed welding. Can also be digital or computerized control.

Single side weld thickness

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.

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.

Application materials

It can be used for welding stainless steel, carbon steel, copper, aluminum, gold, chromium, silver, titanium, nickel and other metals or alloys. It can also be used for various welding between different materials, including copper – brass, titanium-molybdenum, titanium- gold, nickel-copper, etc.

Application industry

Widely used in sheet metal processing, chassis, water tanks, distribution boxes and other cabinets, door and window guardrails, advertising signs, battery components, steel furniture, electronic appliances, metal molds, auto parts, instruments, mobile communications, medical equipment and other industries.
