The STR Series Refrigerant Welding Machine is a high-precision, specialized laser welding system designed for the precise welding of refrigerant lines. Its outstanding performance in thin plate welding stems from the synergistic effect of three key elements: laser physical properties, precision thermal management, and system integration design.
1. Extremely Precise Energy Transfer
Laser welding focuses energy into a tiny spot through optical lenses, generating ultra-high power density (up to 10^6 W/cm² and above). The laser beam does not come into contact with the workpiece, avoiding mechanical stress and deformation. This precision enables the welding of copper and aluminum tubes as thin as 0.5mm or even thinner, while completely preventing burn-through.
2. Minimized Heat-Affected Zone (HAZ)
Laser energy input is highly concentrated and rapid, allowing materials to melt and solidify quickly. The fast thermal cycle results in an extremely narrow heat-affected zone, effectively inhibiting grain coarsening and the burnout of strengthening elements. For thin plate welding, this translates to minimal workpiece deformation and preservation of the mechanical properties of the base material.
3. Stable Cooling System
The integrated compressor refrigeration system provides efficient thermal management, controlling the laser's operating temperature within an extremely narrow fluctuation range (e.g., ±0.1°C). This ensures long-term stability of the laser's output power, eliminating welding defects caused by power fluctuations. Process parameters remain consistent across millions of welding cycles, meeting the requirements of high-quality production.
4. Advanced Pulsed Laser and Intelligent Control
The equipment features precise pulse modulation capability, splitting the continuous laser into high-frequency pulses for accurate control of heat input. The system can be highly integrated with robots, real-time visual sensing, and PLCs, guaranteeing stability and precision throughout the welding process.
In summary, the STR Series Refrigerant Welding Machine's advantages in thin plate welding originate from its precise heat source, minimized heat-affected zone, stable cooling system, and intelligent control capabilities. It is a customized precision thermal processing system for welding thin-walled non-ferrous metals, ensuring high yield and production consistency.
