Do you know what's going on with the seam of welded pipe equipment? Today, Jiangsu Nanyang Machinery Manufacturing Co., Ltd. will explain it to you.
When we are in the practical application of welded pipe equipment, especially in its welding technology, we often encounter the problem of seam opening. The so-called seam opening is that it cannot be completely bonded together during the welding seam, making the product quality unqualified. The seam opening of welded pipe equipment is generally several centimeters or even higher. Having said so much, what causes the welded pipe equipment to open and sew during welding?
The first thing we need to know is that the main reason for the opening of welded pipe equipment may be the material problem, because many materials are made of chemical components. When we weld, everything is in accordance with the normal steps. During the whole welding process, the pipe of welded pipe equipment will crack, which is mainly due to the incomplete adhesion of the parent material. 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. The magnetic rod will generate a relatively strong magnetic field during the welding process of the welded pipe equipment, causing the weld of the welded pipe equipment to reach a very high temperature in a very short time. As long as we find that the weld is black red and there is no welding spark, we can determine that the welding seam is caused by the magnetic rod.
