Types of Laser Welding

Suntop all-in-one handheld laser welding machine uses a handheld welding gun to replace the previous fixed light path. Hand-held welding is flexible and convenient, and the welding distance is longer. It overcomes the limitations of workbench space and the inability to weld when the workpiece size is not uniform. During welding, the heat affected area is small, the deformation is small, the welding depth is large, and the welding is firm. It is a new and more flexible welding process for welding large workpieces over long distances.

Features of types of laser welding


1. The whole machine has an integrated structure design, the equipment occupies a small space, and is equipped with extra-large swivel casters, making it easy to carry and transport.

2. A variety of welding contact tips come standard to meet a variety of welding needs and can achieve high-precision welding. The welds are small, beautiful and firm, and do not require polishing.

3. Professional laser welding software with powerful functions, easy to learn and use, and can be used by general workers without the need for professional welders.

4. The electronic control area is equipped with a cooling fan as standard, which effectively improves the welding stability in high-temperature environments.

5. With visual instruments and water injection ports, the use process can be observed at any time. At the same time, a touch screen control panel is used to make modification of process parameters more intuitive and convenient.

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, significantly reducing parameter debugging time.

7. The equipment has strong scalability and can be connected to wire feeders, robots, etc., and can be equipped with single or double pendulum welding joints.


Details of types of laser welding


1. Laser welding head

Lightweight, only 0.8KG, flexible and convenient for welding metal parts of any shape, adjustable weld width, capable of long-distance welding up to 10 meters. Equipped with a safety temperature monitoring system.

2. Operation interface

Multilingual intelligent control panel, flexible adjustment of welding parameters, multiple sets of welding parameter libraries, cumulative timing of light output, etc.

3. Automatic wire feeding system

Touch screen design, automatic wire filling, fully digital design, supports stainless steel and aluminum wires with diameters of 0.8mm, 1.0mm, 1.2mm, 1.6mm, and 2.0mm.

4. Laser source

We use custom-made fiber with a minimum core diameter of 20um, which has deeper penetration depth and a laser lifespan of up to 100,000 hours. It is maintenance-free and has Bluetooth functionality.

5. Chiller

Dual-cycle water cooling system provides better cooling for the laser source and welding head. The temperature control sensor uses imported brands.

6. Welding connection fiber

The 10-meter-long optical cable adopts an integrated design, effectively avoiding damage to the fiber and problems caused by moisture, greatly improving the service life of the laser components.

Advantages of types of laser welding


1. Easy to operate: you can weld immediately without spending high training costs.

2. Fast and efficient, wide processing range: The laser welding machine has concentrated energy, efficient and high-speed welding, smooth and beautiful welds, and reduces subsequent grinding processes.

3. A wide range of weldable materials: stainless steel plates, iron plates, galvanized plates, aluminum plates and other metal materials can be welded.

4. Break through the limitations of workpiece shape and processing environment: small solder joints and small heat-affected areas: no need to set up a welding workbench, small space occupied, flexible processing, fast welding speed, and can be moved for long-distance operations, without being limited by environmental space.

5. High flexibility: There is no limit on the position of the welding seam. It can access difficult-to-weld parts or local locations, and complete precise welding through precise positioning.

6. Low maintenance cost: The machine has low cost of use and a service life of up to 100,000 hours. It is maintenance-free, installation-free and training-free. It is plug-and-play and is a very practical welding equipment.

Other optional features


Cleaning function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized, effectively removing rust spots, oxide layers, oil stains, etc. on the material surface without damaging the surface characteristics. It is non-contact and does not require cleaning fluid, so it can replace professional cleaning equipment.

Cutting function

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

It can cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other metal sheets with a maximum cutting thickness of about 2mm.

Weld bead cleaning function

It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.

Welding method


A wide range of welding methods are available for welding at any angle. These methods include overlay welding, butt welding, vertical welding, fillet welding, internal fillet welding, and external fillet welding. These methods can be used to weld a variety of workpieces, including complex welds and irregularly shaped workpieces, especially larger ones.
