high performance stainless steel 304 laser welding helical fin tube

Why we choose laser welding fin tubes

Laser welding finned tubes are manufactured by helically winding strip onto tubes. The fin strip vertically applied to the tube is welded at its foot by a welding technique developed and patented by us without filler metal to the tube wall.

The use of the laser technique for the welding of finned tubes offers a number of advantages due to the ability of the beam to be very accurately focused, allowing full use of the beam’s high thermal capacity. Finned tubes are produced in cooper and copper alloys by helically winding a strip onto the tube ans simultaneously soldering both with tin solder.

This fining method results in a good heat conducting connection between the tube and the fins. The slightly corrugated fin foot increases the adherence between tube and fin and improves the heat transfer.
