高頻焊管機(jī)是直縫焊管機(jī)的一種，和其他制管機(jī)不同的地方就在于其焊接方式。高頻焊管機(jī)是利用高頻電阻渦流是管材熱熔并凝結(jié)來制造管材的。高頻焊管機(jī)由于焊接速度快，越來越受到人們的青睞，比如石油管、天然氣等大型管材都是使用高頻焊管機(jī)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.

高頻焊原理/High frequency welding principle：

高頻焊就是高頻率的電阻焊（英文Electric Resistance Welding），所以很多人也把電阻焊管成為ERW管。高頻焊系統(tǒng)一般由整流系統(tǒng)、冷卻系統(tǒng)和控制系統(tǒng)組成。從電網(wǎng)接入的低頻50HZ常規(guī)用電經(jīng)過整流系統(tǒng)的IGBT系統(tǒng)整合后，迅速提升到400KHZ以上，高頻電流加到電感線圈（即感應(yīng)圈）后，利用電磁感應(yīng)原理轉(zhuǎn)換成高頻磁場(chǎng)，并作用在處于磁場(chǎng)中的金屬管材上，由于渦流效應(yīng)是分散在管材周圍的，所以需要在管材內(nèi)部預(yù)置一個(gè)磁棒，受磁棒影響，渦流會(huì)在管材縫隙處集中，然后渦流受集膚效應(yīng)影響，利用電流熱效應(yīng)原理生成熱量，從而使管材邊緣熔化區(qū)熱熔，在外力擠壓下又凝結(jié)在一起，從而實(shí)現(xiàn)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.
