Laser Welding Machine Shorts Tools

Hand-held welding guns replace the previous fixed optical path, allowing for flexible and convenient welding with longer welding distances. It overcomes the limitations of workspace and can be used when the workpiece size is not uniform and automatic welding is not possible. It is mainly used for large workpieces, fixed positions such as internal right angles, external right angles, and flat welding seams. It has a small heat-affected zone, minimal deformation, and a strong and deep weld. It is a new and flexible welding process for long-distance welding of large workpieces.

Features of laser welding machine shorts tools

1. Infrared positioning is utilized for calibrating and verifying the welding position in the welding process, resulting in increased accuracy and a more aesthetically pleasing welding seam.

2. The beam quality is excellent, allowing for precise control and creating fine weld joints. It has a small focusing spot, enabling high-precision positioning and facilitating automation.

3. The wire feeder features a high-precision touch capacitive screen, operates on a 220V drive, and provides automatic wire feed. It offers a more powerful wire feed and prevents wire jamming.

4. Our self-developed handheld welding head is equipped with various safety alarm devices, ensuring easy and flexible operation.

5. We offer a range of welding copper nozzles to cater to different needs, including external welding, internal welding, right angle welding, narrow edge welding, and large spot welding. Customers can select the appropriate welding copper nozzle for their specific requirements.

6. Suntop's patented technology water circulation protection system and auxiliary gas detection effectively prolong the lifespan of the laser lens. It also prevents damage to optical components caused by improper operation.

Advantages of laser welding machine shorts tools

1. Multi-purpose, equipped with versatile nozzles to meet welding, cutting, cleaning, and other functions.

2. Uses a non-contact cleaning method that does not damage the parts substrate, avoiding surface scratches and damage that may be caused by mechanical contact.

3. Can accurately adjust parameters such as laser energy, scanning speed, and focal length to achieve precise control over cleaning depth and range, suitable for various materials and surface cleaning needs.

4. No need to use any chemicals or cleaning agents, the waste generated from cleaning is mainly solid powder, small in volume, easy to store, recyclable, no photochemical reactions, and no pollution.

5. The machine has low operating costs, with a lifespan of up to 100,000 hours, maintenance-free, installation-free, and training-free, plug and play, making it a very practical cleaning equipment.

6. No need for professional operators, ordinary workers can learn in half an hour, can be handheld or used with robots for automatic cleaning.

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

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.
