Understanding YAG Laser Welding Machines and Their Chiller Configuration

How YAG Laser Welding Machines Work
YAG laser welding machines generate a 1064nm wavelength laser beam by electrically or lamp-pumping YAG crystals to excite chromium ions. The resulting laser is focused onto the workpiece surface via an optical system, melting the material to form a molten pool. Once cooled, the material solidifies into a weld seam, completing the welding process.

Types and Applications of YAG Laser Welding Machines

YAG laser welders are classified by laser source, pulse mode, and application:

1) By Laser Type: Lamp-pumped YAG lasers offer lower cost and are suitable for general welding applications. Diode-pumped YAG lasers* provide higher efficiency and longer service life, ideal for precision welding.

2) By Pulse Mode: Q-switched pulsed YAG lasers deliver high precision, suitable for micro-welds and specialty materials. Standard pulsed YAG lasers offer broader versatility and cost-effectiveness.

3) By Application Field: 

* Automotive manufacturing: Welding of body frames and engine components. 

* Electronics manufacturing: Welding of chip leads and circuit traces.

* Hardware industry: Joining of metal fittings for doors, windows, and furniture.

* Jewelry industry: Precision welding of precious metals and gemstones.

Importance of Chiller Configuration for YAG Laser Welders

YAG laser welding machines generate substantial heat during operation. Without effective heat dissipation, laser temperature can rise, leading to power instability, reduced welding quality, or even equipment damage. Therefore, a reliable water chiller is essential for maintaining optimal operating temperature and ensuring consistent welding performance.

Key Factors in Choosing a Laser Chiller

To ensure optimal performance and reliability, consider the following when selecting a laser chiller for YAG laser welders:

1) Cooling Capacity: Match the chiller's cooling power to the laser's output to remove heat efficiently and quickly.

2) Temperature Control Precision: High-precision, intelligent control systems help maintain stable temperatures, minimizing welding defects caused by thermal fluctuations.

3) Safety and Alarm Features: Integrated protections, such as flow, over-temperature, and overcurrent alarms, safeguard the equipment.

4) Energy Efficiency and Environmental Compliance: Choose energy-saving chillers that use eco-friendly refrigerants to reduce operational costs and support sustainability goals.

S&A Closed-Loop Water Chiller CW-5300 for Cooling 2OOW YAG Laser Cleaning Machine

Industrial laser cleaning technique has a wide variety of applications, including aviation, automobile, high-speed train, vessel, nuclear power and so on. It aims to remove the rust, oxide film, coating, painting, oil stain, microorganism and nuclear particle from the surface. In the past three years, many institutes, universities and companies have been showing more and more interests in laser cleaning technique and begin the research and production of laser cleaning machine. During the operation of the laser cleaning machine, industrial water chiller is necessary to be equipped in order to provide effective cooling for the laser.

An Iranian institute, one of S&A customers, also begins the research on laser cleaning technique in which YAG laser with 200W light emitting power is adopted. The salesman of that institute, Mr. Ali, selected S&A CW-5200 water chiller by himself to cool the YAG laser. However, after he got to know the cooling capacity and other parameter, he found that CW-5200 water chiller can't meet the cooling requirement of the laser. In the end, with the professional knowledge, S&A recommended CW-5300 water chiller which is characterized by the cooling capacity of 1800W and the temperature control accuracy of ±0.3℃. It has two temperature control modes, suitable for different occasions. Mr. Ali mentioned that he would like the CW-5300 water chiller to be customized as rack mount type. As customization is available, S&A accepted his request and began the production.

In respect of production, S&A has invested the production equipment of more than one million yuan, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, the warranty period is two years.
