When we use the welded pipe equipment, especially in its welding technology, we often encounter the problem of seam opening. The so-called slotting is that when the welding seam is carried out, it can not be completely bonded together, which makes the product quality unqualified. The seam of welded pipe equipment is generally several centimeters or even higher. After all, what causes the welded pipe equipment What about the seam opening during welding?
The first thing we need to know is that the main reason for the seam opening of the welded pipe equipment may be the material problem, because many materials are made by chemical composition. When we weld, everything follows the normal steps. During the whole welding process, the pipe of the welded pipe equipment will crack, which is mainly the parent material The adhesion is not complete enough. Such cracking is entirely caused by the chemical composition of the raw material.
Another point is caused by the magnetic rod of the welded pipe equipment, which is the physical reason. During the welding process of the welded pipe equipment, the magnetic rod will produce a relatively strong magnetic field, which will cause the welding seam of the welded pipe equipment to reach a very high temperature in a very short time. As long as the welding seam is black and red, and there is no welding spark, we can determine that it is a magnetic rod Caused by welding seam.
