Water-cooled Laser Welder - Overview

A water-cooled laser welder uses a closed-loop system with circulating water to cool the laser, allowing for stable, high-power, and long-duration welding without overheating. This system is more efficient at dissipating heat than air-cooled models, making it suitable for intensive industrial applications, and it maintains consistent performance and can result in better weld quality with less need for grinding or polishing.

Material - Water-cooled Laser Welder

Die steel
The laser welding machine can be used to weld S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302, 2344 and other types of die steel, and the welding effect is better.

Carbon steel
The laser welding machine welds carbon steel with good results. The welding quality depends on the content of impurities. In order to obtain good welding quality, preheating is required when the carbon content exceeds 0.25%. As the carbon content increases, the sensitivity of weld cracks and notches will increase. Both medium and high carbon steel and ordinary alloy steel can be well laser welded, but preheating and post-welding treatment are required to eliminate stress and avoid cracks.

Alloy steel
For laser welding of low-alloy high-strength steel, as long as the selected welding parameters are appropriate, a joint with mechanical properties equivalent to the base metal can be obtained.

Stainless steel
Because the welding speed and heat-affected zone of the laser welding machine are small, the overheating phenomenon and the large linear expansion coefficient of the stainless steel welding are alleviated, and the welding seam has no defects such as pores and inclusions. Compared with carbon steel, stainless steel is easier to obtain deep penetration narrow welds due to its low thermal conductivity, high energy absorption rate and melting efficiency. Welding thin plates with a low-power laser welding machine can obtain a well-formed joint with a smooth and beautiful weld seam.

Copper and copper alloy
Welding copper and copper alloys is prone to problems of infusion and incomplete penetration. Therefore, a heat source with concentrated energy and high power should be used with preheating measures; When the thickness of the workpiece is thin or the structural rigidity is small, and there are no measures to prevent deformation, it is easy to produce large deformation after welding, and when the welding joint is subject to large rigid constraints, welding stress is likely to occur; It is also prone to thermal cracks when welding copper and copper alloys; Porosity is a common defect in copper and copper alloy welding.

Aluminum and aluminum alloy
Aluminum and aluminum alloys are highly reflective materials. When welding aluminum and its alloys, as the temperature increases, the solubility of hydrogen in aluminum increases sharply, and the dissolved hydrogen becomes a source of defects in the weld, and there are many pores in the weld. , And there may be a cavity in the root during deep penetration welding, and the weld bead formation is poor.

FAQ

Q: How does a water-cooled welder work?

A: Water-cooled TIG torches use a cooling system that circulates water through the torch to remove heat. These torches are designed for high-amperage welding applications and extended welding sessions.

Q: What is the primary purpose of the water chiller in a laser cutter?

A: Water chillers for laser cutters are designed to handle high-temperature waste heat through the use of a closed-loop, recirculating system that constantly removes excess heat from targeting optics and conducts this heat into an external source such as a standard refrigerator or another chiller device.

Q: What is the life expectancy of a water-cooled chiller?

A: About 20 – 30 years.Water-cooled chilling systems have a lifespan of about 20 – 30 years. On the other hand, air-cooled units typically last 15 – 20 years.

Q: Are you manufacturer or trading company?

A: We are manufacturer.

Q: What's your best delivery time?
