摘要:
在生产直径大于406 mm（16 in）高频焊管时，为了能正确评估并选择适合的焊接工艺，从焊缝质量、能耗等方面讨论了接触焊和感应焊的差异，并重点讨论了大管径机组对高频感应焊和高频接触焊的影响。综合分析对比得出，高频接触焊相对感应焊具有焊缝质量好、节能效果明显、不需要昂贵的活套和感应线圈以及复杂的阻抗器装置等优势，感应芯棒设计及维护简单方便，成材率高，并且当采用“卷对卷工艺”时，相对于感应焊，接触焊产量高、废品少，能够获得明显较短的焊接V形区长度和较短的焊接区，易于控制板边质量和焊缝质量。
Abstract:
During HFW pipe production with diameter greater than 406 mm（16 in）, in order to correctly assess and select appropriate welding procedure, in this article, it discussed the difference of contact welding and induction welding from weld quality, energy consumption and other aspects, and emphasized the influence on high frequency contact welding and high frequency induction welding of large diameter units. The results showed that relative to high frequency induction welding , high frequency contact welding is with some advantages, such as weld quality is good, energy saving effect is obvious, it doesn’t need the expensive loop, induction coil or a large number of complicated impedor device. The design and maintenance for inside slash mandrel are simple, the breakdown time of replacing the coil and impedor device is shorter and the finished product yield rate is high. In addition, when adopting “reel-to-reel” welding procedure, for contact welding, the output is high and less waste, it can obtain obvious shorter welding angle of V-shaped length and shorter welding area, and easy to control plate edge quality and weld quality.
