1、 The reason for the virtual welding problem of protruding welded nuts
The virtual welding of protruding welded nuts is mainly caused by improper surface treatment before welding, insufficient temperature and time during welding, and other reasons. The virtual welding of protruding nuts can lead to insufficient adhesion between the nut and the substrate, which can easily cause loosening and seriously affect the normal operation of the equipment.
2、 Appearance inspection
The problem of virtual welding in protruding welded nuts is relatively easy to detect in appearance, usually presenting as dents, cracks, and other phenomena. By visually observing the appearance of the nut, check for the above issues. If so, it indicates a high possibility of virtual welding in the protruding welded nut.
3、 Jaw pulling detection
Jaw pulling is a common detection method that can effectively detect the problem of virtual welding in protruding nuts. The specific operation method is as follows:
1. Clamp the tested nut in the clamp and position it axially in the frame.
2. Rotate the nut with appropriate force, hold the circular dial of the force gauge with the other hand, and apply force slightly downwards.
When the nut begins to slide abnormally, or when the force is increased and the nut still cannot meet the specified force requirements, it can be determined that the protruding welded nut is virtual welded.
4、 Other detection methods
In addition to the two commonly used detection methods mentioned above, there are also other detection methods such as ultrasonic testing, X-ray testing, etc. These methods require professionals to operate and require specific equipment and environment.
In short, the problem of virtual welding of protruding nuts is a common issue, but it should be noted that without specific testing equipment, we can indirectly determine the problem of virtual welding of protruding nuts through visual inspection and jaw pulling detection. If the problem cannot be diagnosed, it is recommended to seek professional testing and treatment.
