随着石油价格的飞涨,电费也以百分之七十的大幅度迅速提高。高频电焊管是继热轧无缝管、热锻接管和冷加工管这三种工艺方法之后,利用局部发热焊接获得表面形状好和壁厚均匀的优质管材的一种制造方法。但是,高频大功率输出测量技术发展较晚,焊接装置的研究也较迟,因此,现根据大多数制造厂家的经验和用户对设备的改进经验,以电气系统为主作以介绍。
With the soaring oil prices, the electricity bill is also rapidly increasing by 70%. High-frequency welded pipe is a manufacturing method of hot-rolled seamless pipe, hot-forged pipe and cold-worked pipe after the use of local heat welding to obtain a good surface shape and uniform thickness of the pipe manufacturing method. However, the development of high-frequency and high-power output measurement technology is relatively late, and research on welding equipment is relatively late. Therefore, based on the experience of most manufacturers and users’ experience in improving equipment, the introduction of electrical systems is introduced.
