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. minimise 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.

·  thin, continuous weId seam
·  small heat-affected zone
·  only slight discolouration weld site
·  only slight microstructural change in tube and fin
·  high utilization of heat for forming the seam
·  increased safety because of the avoidance of crevice corrosion due to the high weld integrity between tube and fin
·  no impurity of the weld seam, as the Laser-welding  is carried out under a protective atmosphere
