The processing of grid accessories seems very simple, but it is not simple, because the quality of the accessories directly affects the quality of the grid. If you want to use the grid with confidence, then we need to add With great efforts, and once the parts processing is completed, we also need to conduct quality inspections, so how should we inspect them?

Quality inspection of grid accessories processing:


First of all, there are very direct requirements for the welding skills of the processors. Although it is difficult to see whether the grid is welded well or not, it is difficult to see whether this is welded accurately and whether the overall grid is deformed. These are all related to technology. Closely related, if you want to have a high-quality grid, you must have a high-quality craftsmanship.

Second, we can also look at the entire production process of the grid accessories processing, different processing methods, the production angle and sequence of the entire grid are also different, usually from the order we can distinguish which is more professional, Which one is more layman, so you can find out who is more technically reliable.

Third, it is important to make a net frame, that is, the choice and mastery of the materials. If the selection of the net frame itself does not meet the requirements, then no matter how much work is done, the quality of the finished product is nothing. Of course, this point should be carefully considered.

Precautions for processing and welding of grid accessories:

Pay attention to the processing and welding technology of the grid accessories. Before welding, prepare the welding materials for the grid accessories. Pay attention to the welding mechanism and the amount of welding wire and flux. To bake the welding rods well, bake them in accordance with the quality requirements of the grid engineering, and put them in the incubator after baking. Doing a good job of preheating before welding can reduce the cooling rate of the heated area and avoid the delayed welding cracks, which will affect the welding effect.

It is necessary to follow the welding sequence to keep the welding gap of the grid fittings processing welding project small, to achieve symmetrical welding, longitudinal and horizontal welding. Do a good job of heat treatment after welding, in order to avoid the appearance of cracks, it is necessary to do a good job of heat treatment after welding. The holding time is generally determined according to the thickness of the plate at 1h per 25mm plate thickness.


Through the study of this article, have you already understood the method of quality inspection of grid accessories processing?
