高频焊管机是直缝焊管机的一种，和其他制管机不同的地方就在于其焊接方式。高频焊管机是利用高频电阻涡流是管材热熔并凝结来制造管材的。高频焊管机由于焊接速度快，越来越受到人们的青睐，比如石油管、天然气等大型管材都是使用高频焊管机制造的。
High-frequency welded pipe machine is a straight seam welded pipe machine, and other pipe machine is different from the place of its welding. High-frequency welded pipe machine is the use of high-frequency resistance vortex is the pipe hot melt and condensation to produce pipe. High-frequency welded pipe machine because of the welding speed, more and more people of all ages, such as oil pipe, natural gas and other large pipe are made using high-frequency welded pipe machine.
高频焊原理/High frequency welding principle：
高频焊就是高频率的电阻焊（英文Electric Resistance Welding），所以很多人也把电阻焊管成为ERW管。高频焊系统一般由整流系统、冷却系统和控制系统组成。从电网接入的低频50HZ常规用电经过整流系统的IGBT系统整合后，迅速提升到400KHZ以上，高频电流加到电感线圈（即感应圈）后，利用电磁感应原理转换成高频磁场，并作用在处于磁场中的金属管材上，由于涡流效应是分散在管材周围的，所以需要在管材内部预置一个磁棒，受磁棒影响，涡流会在管材缝隙处集中，然后涡流受集肤效应影响，利用电流热效应原理生成热量，从而使管材边缘熔化区热熔，在外力挤压下又凝结在一起，从而实现焊接。
High-frequency welding is a high-frequency resistance welding (English Electric Resistance Welding), so many people also the electrical resistance welding pipe to ERW pipe. High-frequency welding system generally consists of rectifier system, cooling system and control system. From the grid access to the low frequency 50HZ conventional power through the rectifier system after the IGBT system integration, the rapid increase to 400KHZ above, high frequency current added to the inductor coil (ie induction coil), the use of electromagnetic induction principle into high frequency magnetic field, and Role in the magnetic field in the metal pipe, because the eddy current effect is dispersed in the pipe around, so the need for a preset inside the tube magnet, affected by the magnet, the eddy current will be concentrated in the pipe gap, and then eddy current by skin effect Effect, the use of the principle of thermal effect of heat generated heat, so that the edge of the pipe melting zone hot melt, but also in the external force extrusion together to achieve welding.
