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。
