Advantages of High-Frequency Welding Steel Pipe
High-frequency welded pipe is now often used as a steel, in the machinery industry is very wide application, which is inseparable from its advantages. Here are some advantages of high-frequency welded pipe. High-frequency welding steel pipe, mainly using high-frequency current with skin effect and proximity effect two features, so the edge of the weld current is highly concentrated on the surface, the tube welding edge in a very short period of time the heating to the desired welding temperature and then extruded through the tube to tube welding synthesis. High-frequency welding process has many advantages, the material on the tube and pipe Size wide adaptability. High-frequency welding is not only to improve welding speed and can get a small heat affected zone and weld burn through the good. As the high-frequency welding pipe with good quality, small burr inside and outside, high welding speed, lower power dissipation, etc., are widely used and promoted. In the welded pipe, ...
