Laser welded spiral finned tube is using a laser welding machine processing. In traditional the spiral fin tubes are using high frequency welding, resistance welding and other technology to make the stainless steel fin attached on the steel pipe. Laser Welding Finned Tube, the welding process has its shortcomings that cannot be overcome. While The laser welding spiral finned tube has full automatic welding process,save the manpower cost; secondly, laser welding fin solid and strong, high tensile strength test were quahas a full automatic welding process, save advantages etc. The laser welding machine is the most advanced laser welding equipment for spiral finned tube . Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welded stube.finned tube are better than the traditional cooling pipe. Laser welding principle Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser a
