Why choose refrigerant portable laser handheld welding machine

First, let's review the styles and power of laser handheld welding machines.

1. Water-cooled laser handheld welding machine, power 1500W 2000W 3000W, the cooling system is water-cooled, and pure water or distilled water needs to be added for cooling. The advantage of the water-cooled machine is that the water temperature is used to cool the laser source and the welding head. The disadvantage is that the temperature reaches zero degrees or below zero in winter, and antifreeze needs to be added to the water in the water-cooled machine. The size and weight of the whole machine are relatively bulky.

2. Air-cooled laser handheld welding machine, the laser power is 800W 1200W 1500W, the cooling system relies on the laser source to cool with a fan, the advantage is that the size of the whole machine becomes smaller, the disadvantage is that the ambient temperature is too high, reaching above 45 degrees, and the air-cooled laser handheld welding machine cannot work continuously or continuously.

3. Refrigerant laser welding machine, power 1500W 2000W 2500W, relies on the Freon in the refrigerant to cool the laser source, which is similar to the working principle of the air conditioner in our home. When the temperature of the laser handheld welding machine is too high, our refrigerant cooling system intervenes to cool the laser source to keep it in a good working state at a suitable temperature. There is no need to worry if the ambient temperature is too high, because the refrigerant increases the power to cool the laser source. The injection frequency of the Freon in the refrigerant is once every 3 to 5 years, which is determined according to the actual use of the customer.

The advantages of refrigerant laser welding machine are as follows

The refrigerant portable laser handheld welding machine supports remote control of the operating system and adjustment parameters by mobile phones, and conditional frequency, power, and welding width through physical buttons.

Strong temperature adaptability

Excellent performance in low temperature environment: When the traditional water-cooled handheld welding is used in winter, if the temperature is lower than 0℃, the volume of retained water in the pipeline increases, which may "break" the pipeline and sealing connection of the water cooling system, and it needs to be preheated in advance and wait for the water cooling to 

rise to about 23℃ before normal welding, which is very time-consuming. The refrigerant handheld laser welding machine uses refrigerant as the refrigerant medium, and its freezing point is as low as -155℃, which fundamentally solves the risk of freezing of the cooling medium in winter. There is no need to repeatedly replace the cooling medium, and there is no need to increase the cost of coolant. It can also run stably for a long time at an ultra-low temperature of -20℃, and it can be used as soon as it is turned on.

Stable operation in high temperature environment: When the air-cooled handheld laser welding is high in summer, it is difficult to weld once the operating temperature exceeds 40℃, and the overall heat dissipation is limited, and intermittent light stops are required to ensure its cooling effect. The refrigerant handheld welding is equipped with refrigerant + smart fan for double collaborative cooling. Even at a high temperature of 60℃, it can still provide uninterrupted light for 7×24 hours, regardless of the scorching summer heat. It can directly face more application scenarios, whether it is long-term welding of large pieces or assembly line/automatic welding, it can make welding worry-free.

High cooling efficiency and low maintenance cost

Efficient cooling: Refrigerant direct cooling is a mature cooling technology with high cooling efficiency. It can quickly and effectively reduce the temperature of the equipment and ensure that the laser and other core components operate within the optimal operating temperature range, thereby ensuring the welding quality and stability of the equipment.

Easy maintenance: Compared with the water cooling system, the refrigerant laser handheld welding machine does not need to be regularly inspected and filled with antifreeze, and there is no problem of cooling water blockage due to bacterial colony growth, which reduces the maintenance cost and failure rate of the equipment and brings users a better welding experience.

Easy to operate

Integrated design: Usually the laser, welding system, handheld laser gun and cooling system are integrated together. The integrated structural design makes the equipment smaller and lighter, and occupies only About 0.24㎡, easy to carry and operate, convenient for users to better handle complex welding tasks in different work locations, and can flexibly respond to various welding scenarios.

Humanized operation: Some refrigerant laser handheld welding machines adopt a knob design, which can operate complex processes with one button. You only need to turn on the machine and select the welding process package to start welding. Users can also build their own process packages according to their needs to meet personalized welding needs. In addition, the welding gun is of moderate size and ergonomic design, allowing users to better complete work tasks at various angles, and it feels comfortable and easy to hold, and it is not easy to get tired after long-term use.

Good welding effect

High weld quality: The refrigerant laser handheld welding machine can output a high-energy-density laser beam to quickly melt the material and form a solid weld. The weld is smooth and beautiful, without defects such as pores and cracks. The welding strength reaches or even exceeds the parent material itself, which can meet the welding requirements of high-quality products.

Small heat-affected zone: Laser welding is a non-contact welding process, and no pressure is required during the operation. Its working principle is to use high-energy-intensity laser The beam is directly irradiated on the surface of the material. Through the interaction between the laser and the material, the material is melted inside, and then cooled and crystallized to form a weld. The heat effect in the welding area is small, and it is not easy to cause deformation, blackening, and marks on the back of the workpiece. It is suitable for precision welding tasks with strict deformation requirements.

Wide range of applicable materials

Various metal materials: It can weld a variety of common metal materials such as carbon steel, stainless steel, copper, aluminum, galvanized sheet, etc., to meet the diverse welding needs of different industries and users.

Energy saving and high efficiency

High electro-optical conversion efficiency: The electro-optical conversion efficiency of the refrigerant laser handheld welding machine is relatively high, and the energy consumption is low. Compared with traditional arc welding, it can save about 80%-90% of electricity. Long-term use can greatly reduce processing costs.

Fast welding: It has a faster welding speed, can improve production efficiency, reduce labor costs, and create greater economic benefits for enterprises.

High safety Multiple safety protection: It is equipped with professional laser safety operation protection functions, such as laser protection glasses, safety locks, etc., to ensure the safety of operators during work and reduce damage to the eyes. In addition, the switch is only effective when the welding nozzle touches the metal, and the switch has body temperature sensing, which further improves the safety of operation.
