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
