Stainless Steel Laser Welding Finned Tube
In traditional the spiral finned tubes are using high frequency welding, resistance welding and other technology to make the stainless steel finned attached on the steel pipe. These kinds of welded spiral 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 finned solid and strong, high tensile strength test were qualified; laser welding more efficiency advantages etc.
The laser welding machine is the most advanced laser welding equipment for spiral finned tube . Laser welded spiral finned tube is using a laser welding machine processing. Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welded spiral finned tube are better than the traditional cooling pipe.
3.Heat Recovery Plants
1.thin, continuous weId seam
2.small heat-affected zone
3.short heating time
4.only slight microstructural change in tube and finned
5.high utilization of heat for forming the seam
6.high welding speed
7.no impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere
Laser welding principle:
Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser and metal, metal absorption laser into heat to make the metal melt after the formation of cooling crystallization welding.
