The working principle of a welded nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking under dynamic load will be reduced.
Welding nuts have a unique advantage due to their wide application range and good welding reliability. However, welding and positioning of weld nuts is difficult and complicated. How to make full use of the unique advantages of welding nuts, research and explore a positioning electrode device that is easy to use, reliable, efficient, and durable as a pipe fitting.
The structural characteristics of welding nuts determine the characteristics of the welding process. Welding nuts have a wide range of use, high welding reliability and good quality, but the welding positioning is complicated and full of sails and difficult to apply. After the positioning problem is solved, welding nuts will have obvious application advantages.
Welding nuts perform color detection and salt spray test detection on the screws that are electroplated back. Look at the color of the screws that are electroplated. How smooth is the surface of the screw? The salt spray test detects the rust time of the screw or how many hours the salt spray screw passes before it rusts. After that, the screw shipment was tested. The method is to select unqualified screws. Send the highest quality screws to customers. Ensure the quality of the screws.
The working principle of a welded nut is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking will be reduced in dynamic loads. In some important occasions, we will take some anti-loose measures to ensure the reliability of the nut locking. The use of a lock nut is one of the anti-loosening measures.
There are also two types of lock nuts. One is to use two identical nuts to be screwed on the same bolt, and a tightening torque is added between the two nuts to make the bolt connection reliable. The case of welding nuts is mostly based on the limitation of the process. If two very large plates are to be connected, one person cannot do it, so the nuts must be welded to tighten the bolts.
