laser welding

Laser welding fin tube： Welding-forming surface-extended thermal-transfer tubes The fin strip is welded continuously and spirally wound onto bare tube. And the tube and fins are bonded together by using lase welding technique. 100% welding between fin and base tube without using any filler material, The laser welding process is carried out under the protective atmosphere, and no impurity of the weld seam The Laser Welded Fin Tubes are widely applied in fired heaters, heat exchanger, boilers, economizers, pre-heaters, coolers, heat pipes, heaters etc…
