Welding pressure
Frequency welded pipe welding pressure is one of the main parameters of the welding process, after the two edges of the tube is heated to welding temperature and squeezing produce welded under pressure to form a common metal grain that is mutually crystals. Since the tube width and thickness tolerances may be present, as well as wave soldering temperature and welding speed, it is likely to involve welding pressing force changes. High-frequency welding pipe extrusion amount is generally controlled by adjusting the distance between the rollers squeeze, squeeze rollers can also use the front and rear differential to control the tube circumference.

Welding speed
Welding speed is one of the main parameters of welding technology, heating system and it welds the strain rate and the mutual crystallization speed. When high-frequency welded pipe, welding quality with speed up welding speed increases. Therefore, when a high-frequency welded pipe, mechanical equipment and should be in the welding apparatus unit.
