Notes on welding of stamping elbow
Stamped elbow is widely used in piping engineering parts, and strict welding process is required when making stamped elbow. The perovskite type needs to be dried at 150 ℃, and the treatment time is strictly controlled to be 1 hour to prevent the increase of carbon content near the welding and improve the quality of the welding workpiece.
When welding the stainless steel elbow, it is better to control the temperature within 600 ℃ to ensure that the structure of the stainless steel elbow will not be damaged. Argon can be used to protect the stainless steel during welding to prevent the stainless steel from reacting with other elements in the air. When cutting the stainless steel elbow, avoid using ordinary grinding wheel, use special grinding wheel or plasma cutting.
During welding, the carbon content of the metal in the stamping elbow and the connecting pipe increases when heated repeatedly. When the carbon content of the metal increases, the brittleness of the metal increases and the stamping resistance decreases. Therefore, the welding current should be controlled during welding, and the welding current is reduced while controlling the temperature and repeat heating.
The above are the precautions for the welding of stamping elbows. Haihao Group has professional production equipment and an experienced welding team. The stamping elbows we produce strictly implement welding standards and have excellent quality, which are well received by domestic and foreign customers. Our products include: flanges, elbows, steel pipes, pipe fittings, tees, valves and other products that will be used in various pipeline projects. In addition, we support non-standard customization and prefabrication. You are welcome to consult and purchase.
