There are many kinds and technologies of laser welding finned tubes

There are many kinds of laser welded finned tubes when they are used. In operation, high-frequency welded finned tubes are mainly used. Although it is more effective in product quality and production automation compared with inlay, brazing and other methods, the root of high-frequency welded finned tubes is difficult to weld through and there are wrinkles at the root. As a result, high-frequency welded finned tubes still have many shortcomings in heat transfer efficiency and ash prevention convenience. In view of the above reasons and in response to the policies on energy conservation and emission reduction.
