Features of laser butt welding


1. Multi-purpose machine, equipped with multi-functional nozzles, meets welding, cutting, cleaning, and other functions.

2. Independently developed handheld welding torch, equipped with various safety alarm devices, easy and flexible to operate.

3. The machine has multiple safety alarm functions. The welding copper nozzle's trigger switch is only effective when it touches the metal and securely clamps the metal sheet. The welding copper nozzle will automatically lock the light after moving away from the workpiece. The machine has high safety to ensure absolute safety for operators during work.

4. Suntop's patented technology of water circulation protection system and auxiliary gas detection effectively extends the service life of the laser lens and prevents damage to optical components caused by improper operation.

5. Comes with various welding copper nozzles such as flat angle, inner angle, outer angle, etc. Different nozzles can be replaced according to different welding needs to meet various welding requirements.


Details of laser butt welding


1. The laser cleaning head is lightweight, weighing only 0.8KG. It is flexible and convenient for welding any shape of metal parts. The welding seam width is adjustable, and it can carry out welding at a distance of up to 10 meters. It is equipped with a safety temperature monitoring system.

2. The operation interface features a multi-language intelligent control panel. It allows for flexible adjustment of welding parameters and has a multi-group welding parameter library. It also includes features such as light output cumulative timing.

3. The automatic wire feeding system has a touch screen design and allows for automatic wire filling. It is fully digital and supports stainless steel and aluminum wire with diameters of 0.8mm, 1.0mm, 1.2mm, 1.6mm, and 2.0mm.

4. The laser source we use is customized fiber with a minimum core diameter of 20um, which allows for deeper penetration. It has a laser life of up to 100,000 hours and is maintenance-free. It also has Bluetooth capability.

5. The water cooler features double circulation water cooling, which helps to keep the laser source and weld head cooler. The temperature control sensor uses an imported brand.

6. The welding connection fiber is designed with a built-in 10 meters long fiber optic cable. This design effectively avoids damage to the fiber and problems caused by moisture, greatly improving the service life of the laser device.

Advantages of laser butt welding


1. Laser beam is easy to focus, high power density, easy to realize rapid positioning and precision processing; laser can transmit light wave energy, can be microfabrication of materials.

2. Good beam quality: high directionality, monochromaticity and coherence, easy to use with the CNC system; pulsed output mode so that the laser beam is easy to get a smoother weld.

3. Flexible and convenient: the computer can be used to change the process parameters, you can realize the spot welding, butt welding and other automatic welding operations; can also be fixed using mechanical or pneumatic fixtures to clamp the workpiece on the table for manual operation.

4. Wide range of applications: a multi-purpose machine, can be used for a variety of sheet metal material cutting, welding, laser cleaning, weld cleaning.

5. Non-contact processing: without using electrodes and tools to pressurize the material to achieve processing in the cold state, does not produce thermal deformation and subsequent deformation.

6. Low maintenance cost: advanced laser technology with stable and reliable performance. Laser life of up to 100,000 years, low maintenance costs.



Welding method


A variety of welding methods are available, allowing for welding at any angle, including stack welding, butt welding, vertical welding, flat angle welding, internal angle welding, external angle welding, and more. These methods can be used to weld various workpieces, including those with complex weld seams and irregular shapes, particularly larger workpieces.
