Aluminum tube welding.
With the rapid development of the manufacturing industry, more and more low cost welded aluminum tubes be used. Especially the field of the heat exchanger using a large number of the welded tubes.
 
Welding aluminum tube require the power of welding seam have big density, the faster welding speed, the better quality of seam. For the technical difficulties of aluminum tube welding process, high frequency power supply should adopt higher frequency, to make seam heat affected zone narrow and current of tube inner wall small. High frequency power supply can use speed tracking work mode to ensure the high quality of welding. Our company the earliest develop the aluminum tube production with solid state high frequency induction power supply, it has some advantage such as high production speed, heat affected zone narrow, and high quality of welding seam. It can use different size aluminum strip to continuous produce different size tube through high frequency welding.

Power:60-1800KW
Characteristic:(1)The development of High Efficiency Solid State HF Welder has responded to the state industrial policy of energy-saving emission reduction. It has many advantages such as high power factor for welder, small harmonic interference on power grid, protection sensitive, output stability and compacted structure.
(2)It has high operation stability and never occur a failure and accident since the equipment has been putting on the market from the first half of 2009.
(3)Power factor can achieve above 0.93.
We are the first company who successfully applies the new technology (high power switching power supply) to steel pipe, stainless steel pipes and aluminum pipes in the induction heating field. The various main technical parameters of this product are at the leading level in domestic. Our self-developed core components of switching power supply has been declared a national patent. This product has been stable operating at clients’ mills and has fully affirmed by clients.
