Air-cooled Laser Welding Machine

Handheld laser welding machines are becoming popular in several part manufacturing industry. They have some advantages and disadvantages over traditional welding techniques. Hence, they have variable applications. This article compared both welding systems, to inform you on choosing the right one for your project.

Air-cooled Laser Welding Machine

The hand-held laser welding machine uses a continuous fiber laser as the light source and is equipped with a self-developed hand-held welding head. The shape, structure and man-machine are optimized based on humanization and work effectiveness. The hand-held welding head can be produced according to actual production. Customized, very suitable for non-standard production, Air cooling design, long-term welding does not get hot, small diameter, easy to hold, has the advantages of simple operation, beautiful welding seam, fast welding speed, and no consumables.

An air-cooled laser welder is a type of laser that uses air cooling to stay cool. This is usually done with a built-in fan. The fan helps to prevent the laser from overheating during use.

The body is small and easy to move. It can be placed in the trunk of a car and is cheaper.

Increase your productivity and optimize workflow efficiency with an portable air-cooled laser welding machine. The machine is equipped with advanced air-cooling technology, without a complex and bulky water-cooling system. This not only simplifies setup and maintenance but also enhances workspace portability and flexibility. The efficient air cooled system ensures consistent performance even during long welding sessions, maximizing uptime and minimizing downtime.

Handheld Air Cooling Laser Welding Machine Material Range

Precision is critical for laser welding, and portable air-cooled laser welding machine deliver exceptional precision and repeatability. High-power laser generators combined with advanced optics and beam delivery systems allow for high precision, ensuring precise welds even in complex and delicate applications. Benefit from a highly customizable system that allows you to adjust key parameters such as laser power, pulse duration, and frequency to achieve the welding characteristics required for each application.

Unlike water-cooled laser welding machines that use liquid cooling systems to dissipate the excess heat generated during operation, air-cooled machines rely on air circulation for cooling purposes. This makes them more compact and easier to integrate into different manufacturing environments, as they do not require external water cooling systems or complex plumbing.

Air-cooled Laser Welding Machine Advantages

Air-cooled laser welding machines are commonly used in various industries, including automotive, aerospace, electronics, and jewelry manufacturing. , such as:

  1. Compact Design: The absence of water cooling systems makes air-cooled machines more compact and space-efficient. They can be easily integrated into existing production lines or workstations.
  2. Lower Maintenance: Air-cooled systems typically have fewer components and do not require regular maintenance associated with water cooling, such as filter replacements or water quality monitoring.
  3. Cost-Effective: Air-cooled laser welding machines are generally less expensive compared to their water-cooled counterparts. They eliminate the need for additional water cooling infrastructure, reducing upfront and operational costs.
  4. Mobility: The absence of water connections makes air-cooled machines more portable and suitable for on-site welding applications or situations where mobility is required.

Air-Cooled Laser Welding Machine VS Water-Cooled Welding Machine

Size and weight are different:

Air-cooled handheld laser welding machine is very small in size and weight because there is no water tank, and the weight is basically 30-40 kilograms. The volume is also basically half the size of water-cooled handheld laser welders. Therefore, in terms of mobility, air-cooled handheld laser welding machine has a very big advantage indeed!
The water cooler is a separate device, so the device takes up more space, high-power laser equipment water-cooled volume and weight is usually more than double the air-cooled equipment.

Working hours vary

The cooling effect of water cooling is better than that of air cooling. In the past, air-cooled laser welders had shorter operating times. They needed to stop for a few minutes after running continuously for a while.

IGOLDENLASER mosaic laser source can run for a long time like water-cooled sources. It can work well in temperatures from -20 to 55 degrees Celsius.

Water-cooled laser welding is typically available 24 hours a day.

Comparison of Laser Welding and Traditional Welding

The traditional welding equipment is mostly carbon dioxide shielded welding and arc welding, and the speed is basically 10mm/s, while the speed of the lazer welding machine is generally 20-100mm/s according to the thickness of the material, and the efficiency is basically increased by about 5 times. The air-cooled type The air cooling laser welding machine is mainly aimed at the thin plate field, and the welding performance of the thin plate within 4mm is much higher than that of the traditional welding process. Materials after traditional welding need to be polished, otherwise it is difficult to directly proceed to the next step. However, the materials after laser welding are beautiful and have small weld marks, and the next step can be carried out with almost no treatment.

Regular maintenance of laser cooling equipment

Both water-cooled and air-cooled cooling equipment require regular maintenance during use. Regularly replace the water in the water tank to ensure that the water is pure. Distilled or purified water is recommended. There should be no debris in the cooling water, and pay attention to whether the water in the return pipe flows smoothly.
Whether it is water-cooled or air-cooled system, the water tank or fan should be free of dirt and should be cleaned regularly.

The laser welding machine also needs to pay attention to the following points during operation:
1, if the water tank is not running or there is no water, please do not use and exclude the semiconductor laser welding machine. Because the semiconductor laser welding belongs to high temperature thermal processing, if not water cooling will cause serious consequences.

2、Please turn off the power in time if there is any abnormality during operation. After the vibrating mirror stops working, some inspection and maintenance work should be carried out.
