The advantages over conventional MAG/HF welding are of decisive importance.
The complete connection between the fins and the base tube brings about excellent heat transfer and up to 2.5 times higher thermal performance of the finned tubes.
The continuous weld prevents notch effects and V-Corrosion and the formation of cracks are hence avoided also in the case of possibly oscillating finned tubes.
The low base metal heating during welding and the high speed of travel of up to 20m/min. minimize the heat-affected zone in the base tube. Complete melting of the tube and a related metallurgical transformation of the parent metals are hence excluded.
Weld spatter is almost completely avoided by the finned tube LASER welding process, with the advantage that the risk of fouling of the finned tubes is minimized.
