The process is the first high-frequency welded pipe uncoiling, flattening, on the head and tail cut, weld on steel with the right looper material storage, you can shape it. After molding is welded, remove burrs, its inspection, pipe straightening, and finally hydrostatic testing, flaw detection, all work ready after that finished it.
Typically, high-frequency welded pipe welding process welding speed is the main parameters, the speed and the heating system, weld deformation speed, and the speed of each crystal are all related. Frequency welded pipe welding quality also with welding speed and progressive. This is because the high-frequency welded to shorten heating time, leaving the edge of the heated zone width is narrowed, greatly limits shortening the time of forming a metal oxide. If the welding speed is too low, it will not only widens the heating zone, but also with the input of the molten zone width and change into heat, a large burr is formed inside, resulting in problems.
