Features of laser clad welding

1. Use infrared positioning to confirm the position of the welding head and ensure accurate positioning during the welding process. The welding position is more precise, the weld is smooth and aesthetically pleasing, easy to polish, and requires no or minimal post-welding treatment.

2. The self-developed handheld welding head is equipped with various safety alarm devices for convenient and flexible operation.

3. Equipped with a high-precision wire feeder, capacitive touch screen, 220V drive, automatic wire feeding, providing stronger and non-jamming wire feeding.

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

5. Equipped with a 10-meter imported optical fiber, overcoming the limitation of workspace and allowing flexible and convenient outdoor and long-distance welding.

6. Comes with various welding copper nozzles, including flat, inner corner, outer corner, etc. Different nozzles can be replaced according to different welding needs to meet various welding requirements.

Advantages of laser clad welding

1. Flexible and convenient. Integrated design. The laser, water tank and control part are combined together. It occupies a small area and has low site requirements. It is equipped with movable pulleys. The work position can be adjusted at any time according to on-site requirements, making it convenient and flexible.

2. The operation is simple and easy to learn, with no technical threshold required. Ordinary workers can operate it after short-term training and easily achieve high-quality welding results.

3. The welding heat-affected zone is small, the yellowing and blackening areas on both sides of the weld are small, and the overall deformation of the workpiece is small; the heap height of the welding surface is small, and secondary grinding is not required, reducing labor and time costs.

4. A variety of welding methods can be used to achieve any angle welding, cladding welding, butt welding, vertical welding, flat fillet welding, internal fillet welding, external fillet welding, etc., and can be used for various workpieces with complex welds and large irregular-shaped workpieces. welding.

5. Concentrated energy, small heat-affected zone, no deformation, no blackening, large welding depth, fine and beautiful welds, firm welding, and the strength of the welds reaches or even exceeds the strength of the base material itself.

6. The use and maintenance costs are low, the electro-optical conversion efficiency is as high as over 30%, the lifespan is more than 100,000 hours, and it is basically maintenance-free.

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.

Other optional features of laser clad welding

Cleaning Function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be achieved, effectively removing rust, oxide layers, oil stains, etc. from the material surface without damaging its characteristics. It has a non-contact feature, does not require cleaning solution, and can replace professional cleaning equipment.

Cutting Function

It can perform simple cutting, and welding and cutting can be freely switched by simply changing the welding copper nozzle to the cutting copper nozzle, which is very convenient.

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

Weld Seam Cleaning Function

It can effectively remove impurities such as oxides, welding slag, oil stains, and dust generated during the welding process, making the weld seam surface clean. This not only helps improve the quality of the weld seam but also enhances its strength and appearance. Laser cleaning has high precision and controllability, allowing thorough cleaning of the weld seam surface without damaging the base material.
