What are the treatment methods for galvanized steel pipe welding

Galvanized steel pipe is a commonly used material in modern life, and welding is the most commonly used connection method. The quality of welding is directly related to the safety and stability of the product. So what problems should we pay attention to to ensure the quality of welded products?

1. Steel pipe thickness In the production and use of welded steel pipes, the thickness of the steel pipe is a very important parameter. However, due to production and processing reasons, the thickness of the steel pipe may have a certain deviation. These standards specify parameters such as size, thickness, weight, and tolerance of welded steel pipes to ensure the quality and safety of steel pipes. The deviation of the thickness of welded steel pipes may affect the quality and safety of steel pipes. If the thickness deviation of the steel pipe is too large, it may cause the bearing capacity of the steel pipe to decrease, thereby 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 deviation of the thickness of welded steel pipes. In actual production and use, it is necessary to strictly control and manage according to the standards to ensure the quality and safety of steel pipes.

2. Pipe mouth In the process of steel pipe welding, another important thing is the treatment of the pipe mouth of the steel pipe. Whether it is suitable for welding greatly affects the quality of the finished product after welding. First of all, there should be no floating rust, dirt, and grease at the mouth of the steel pipe. These wastes greatly affect the welding quality, which will cause the weld to be uneven and broken during the welding process, and even affect the entire welded product. The flatness of the cross-section is also an important matter that must be done before welding. If the cross-section inclination angle is too large, it will cause the steel pipe to bend and appear at angles during welding, affecting the use. During welding, the burrs and attachments at the fracture of the steel pipe should also be checked, otherwise, it will not be welded. The burrs on the steel pipe will also scratch the workers and damage their clothes during processing, which greatly affects safety.

3. The weld of the steel pipe refers to the weld formed by the steel pipe during the welding process. The quality of the steel pipe weld directly affects the performance and safety of the steel pipe. 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, resulting in leakage points, fractures, and other problems in the steel pipe during welding, thereby affecting the quality and safety of the product.

Therefore, in the production and use of steel pipes, strict quality control and inspection of steel pipe welds are required to ensure the quality and safety of steel pipes.
