The quality of welding is directly related to the safety and stability of the product. So to ensure the quality of welded products, what issues should we pay attention to?

First, steel pipe thickness. In the production and use process of welded steel pipes, the thickness of the steel pipe is a very important parameter. However, due to production and processing reasons, there may be certain deviations in the thickness of the steel pipe. These standards specify parameters such as size, thickness, weight, and tolerances of welded steel pipes to ensure the quality and safety of steel pipes. Deviations in the thickness of welded steel pipes may impact the quality and safety of the steel pipes. If the thickness deviation of the steel pipe is too large, the load-bearing capacity of the steel pipe may be reduced, thus affecting the safety and stability of the product. To control the deviation of the thickness of welded steel pipes, international standards usually stipulate the standards for the allowable deviations of the thickness of welded steel pipes. In actual production and use, it needs to be controlled and managed strictly by the standards to ensure the quality and safety of steel pipes. Strictly control the thickness of steel pipes. Steel pipes of the same specifications have a thickness tolerance of ±5%. We strictly control the quality of each steel pipe. We conduct thickness testing on every batch of steel pipes to prevent substandard products from entering the market, safeguard the rights and interests of consumers, and ensure The safety and reliability of each steel pipe.

Second, the nozzle. In the process of steel pipe welding, another important thing is the treatment of the nozzle of the steel pipe. Whether it is suitable for welding will greatly affect the quality of the welded product. First, it is necessary to keep the steel pipe mouth free of floating rust, dirt, and grease. These wastes greatly affect the quality of welding, causing unevenness and fracture of the weld during the welding process, and even affecting the entire welded product. Smooth cross-section is also an important matter that must be done before welding. If the cross-section inclination angle is too large, the butt welding of the steel pipe will be bent and the angle will appear, which will affect the use. During welding, you should also check the burrs and attachments at the fracture of the steel pipe, otherwise, the welding will not be possible. Burrs on steel pipes may scratch workers and damage their clothes during processing, which greatly affects safety. Considering the user’s welding problems, a nozzle processing technology has been added to the process to ensure that the nozzle interface is smooth, flat, and burr-free. During welding, there is no need to re-cut the nozzle, making it convenient for users to butt weld in daily use. The implementation of this process can not only reduce the waste of waste materials that we used to saw during welding, but also increase production efficiency, reduce welding deformation, and further improve the welding quality of the product.

Third, welded steel pipe welds refer to the welds formed during the welding process of steel pipes. The quality of steel pipe welds directly affects the performance and safety of steel pipes. If there are defects in the steel pipe weld, such as pores, slag inclusions, cracks, etc., it will affect the strength and sealing of the steel pipe, causing problems such as leakage points and fractures in the steel pipe during the welding process, thus affecting the quality and safety of the product. Therefore, during the production and use of steel pipes, strict quality control and testing of steel pipe welds are required to ensure the quality and safety of steel pipes. To ensure the quality of welding, we specially add turbine welding detection equipment to the production line to detect the welding status of each steel pipe. During the production process, if welding problems occur, we will immediately call the police to prevent problematic products from being imported into the country, in the finished product package. Non-destructive testing, metallographic analysis, mechanical property testing, etc. are performed on each batch of steel pipes shipped from the factory to ensure that downstream customers do not suffer from unstable product performance and slow progress in welding work due to steel pipe problems during processing operations.
