The working principle of the welded nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic loads.
Weld nuts are unique in their wide range of use and good welding reliability. But the welding nut welding positioning is difficult and complicated. How to make full use of the unique advantages of welding nuts, research and discuss a positioning electrode device that is easy to use, reliable, efficient and durable.
The structural characteristics of the welding nut determine its welding process characteristics. The welding nut has a wide range of applications, high welding reliability and good quality, but the welding positioning is complicated and the application is difficult. After the positioning problem is solved, the welding nut will have obvious application advantages.
Weld nuts are color tested and salt spray tested for plated back screws. See if the color of the screws returned by electroplating is good. How smooth is the surface of the screw? The salt spray test detects the rust time of the screw or how many hours of salt spray the screw will pass before it rusts. After that is the inspection of the screw shipment. The method is to pick out the unqualified screws. Send the best quality screws to customers. Guaranteed screw quality.
The working principle of welding nuts is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of lock nuts is one of the anti-loosening measures.
There are also two types of lock nuts. One is to use two identical nuts to screw on the same bolt, and add a tightening torque between the two nuts to make the bolt connection reliable. Most of the welding nuts are based on the limitations of the process. If you want to connect two large plates, one person cannot do it, so you need to weld the nuts to screw the bolts.
