Discover groundbreaking innovation with our precision-engineered fins, available in either solid or serrated forms. These fins are expertly helically wound and impeccably welded by our state-of-the-art automatic laser finning machine. Our pioneering laser finning technology assures a flawless bond between fin and tube, reducing heat input while maximizing heat transfer efficiency and enhancing corrosion resistance.
Advantage
Our revolutionary laser welding technique delivers transformative benefits over traditional MAG/HF welding methods, establishing new industry standards.
Experience unparalleled heat transfer capabilities with a complete fusion of fins and the base tube, achieving up to a staggering 2.5 times improvement in the thermal performance of finned tubes.
The seamless welding process eliminates notch effects, efficiently preventing corrosion and reducing the risk of cracks, even in dynamically oscillating finned tubes.
By applying minimal heat to the base metal during welding and operating at high speeds up to 20m/min, the heat-affected zone is substantially minimized, preserving the base tube's structural integrity. Our method avoids complete melting and any metallurgical transformation of parent metals, ensuring an unmatched degree of durability and longevity.
