Firstly, the importance of steel pipe welding joint treatment. The treatment of steel pipe welding joints is an important step to ensure the quality of steel pipe welding. Under normal circumstances, there are welding defects, pores, and cracks in the welded steel pipe welds. If not handled in a timely manner, it will affect the strength and sealing of the weld, thereby shortening the service life of the steel pipe, and even affecting the safety of use.

Secondly, the steps for handling steel pipe welding
1. To cut uneven and porous welds, you need to use tools such as Angle Grinders to cut them out. The cut weld seam should be smooth and free of pores and foreign objects to facilitate subsequent processing.
2. Grinding: Cut the surface of the weld seam to remove burrs and sharp edges during the cutting process, in order to avoid causing new defects. You can use grinders, electric angle grinders, and other tools for grinding.

Filling is an important step in repairing welding defects and improving welding quality. The filling material should be the same or similar to the steel pipe material. Before filling, the steel pipe weld should be removed first, then the filling material should be uniformly heated to the melting point, and then applied to the weld until the filling material solidifies. Grinding treatment.

Steel pipes are used for various applications, such as oil pipes, sewage pipes, etc. Use steel pipes. During the use of steel pipes, we need to weld them. So what is the welding method for steel pipes?

Firstly, what are the welding methods for steel pipes, including electrode arc welding, immersion arc welding, molten inert gas shielding welding, and other welding methods? Before performing electrode arc welding, we need to clean the grooves of two steel pipes, then use manual welding to evenly heat the grooves, place the electrodes, and use the arc for welding. Next, we will perform lid welding on the bottom welding. Minor welding.

Secondly, what should be noted when using steel pipes?

There are various types of steel pipes, including spiral steel pipes, straight seam steel pipes, galvanized steel pipes, stainless steel pipes, etc. When we use steel pipes, we must choose different types of steel pipes according to the usage situation, such as load-bearing columns in steel structures, such as buildings and dams. Straight seam steel pipes can be used, but spiral steel pipes cannot be used. Water pipes should be made of stainless steel pipes instead of galvanized steel pipes, etc.
When we use steel pipes, we usually need to connect two steel pipes. There are multiple methods for connecting steel pipes. We connect steel pipes through flange or welding. Before welding steel pipes, we must check for any issues, such as misalignment of the pipes. It is necessary to clean the oil stains on the surface in a timely manner. During the welding process, we must move the welder evenly in order to weld. The welding current cannot be too high. Or it may be too small, otherwise it will affect the welding quality.
Before using steel pipes and other steel materials, we must carry out relevant preservation work. For example, steel pipes and other steel materials cannot exist in damp places. When storing steel pipes, we should not place them directly on the ground. After placing the wooden mat on the ground, we can store the steel pipes. Corrosive materials should not be placed in the storage area of steel pipes.
