(Summary description)The editor of Welded Clamp Nut factory reminds us that for nut welding, torque detection is more commonly used in the process. Set the required torque value, and then screw the nut. If the nut does not detach and the base material is not deformed at the torque value, then the welding quality is qualified. Conversely, if the nut is screwed off without reaching the set torque value, it is unqualified. Torque detection method is also a non-destructive detection method.

Do you know how to judge the quality of welded nuts? Today, the editor of Welded Clamp Nut factory will take you to a brief look.
1. Visual inspection, it is a relatively normal phenomenon that the surface of the nut is relatively uniformly burned after welding. If only local burns are severe, the welding may fail. Three solder joints can be clearly seen on the back of the welded part. If one or two of them are not obvious, the welding quality may not be satisfactory.
2. After visual inspection, in order to quickly determine the welding quality before production, the welding nut will be knocked directly with a tool. If the nut can tear the base material, the welding quality will be better. If it falls off very easily, the base metal is not torn and it is a false weld.


3. The editor of Welded Clamp Nut factory reminds us that for nut welding, torque detection is more commonly used in the process. Set the required torque value, and then screw the nut. If the nut does not detach and the base material is not deformed at the torque value, then the welding quality is qualified. Conversely, if the nut is screwed off without reaching the set torque value, it is unqualified. Torque detection method is also a non-destructive detection method.
4. In addition to the torque, the pressure resistance value of the welded nut can also be tested by a press. Set the pressing speed according to the pressure test requirements, and then press until the nut is separated from the base material. At this time, you can record the maximum value of the pressure Z, and then compare the standard requirements to determine, at the same time you can see whether the nut has brought out the base material.
The above is the editor of Welded Clamp Nut factory: a brief introduction to the method of judging the quality of welded nuts.
