How to check the processing quality of grid accessories?

      Grid accessories processing seems very simple, but it is not simple, because the quality of accessories processing directly affects the quality of the grid. If you want to use the grid with confidence, then we should strengthen the processing of grid accessories, and once the parts processing is completed, we also need to carry out quality inspection, so how should we detect?

       Quality inspection of grid frame accessories processing:

       First of all, there are very direct requirements for the welding technology of the processor. Although it is difficult to see whether the grid is welded well or not, whether the welding is accurate or not and whether the overall grid structure has deformation are closely related to technology. If you want to have a high-quality grid frame, you must have a high-quality craft.

       Second, we can also look at the whole production process of grid accessories processing. Different processing methods have different manufacturing angles and orders for the whole grid frame. Usually, we can distinguish which is more professional and which is more layman from the sequence, so that we can find out the side with more reliable technology.

       Third, there is another important point in the construction of grid structure, that is, the selection and control of materials. If the material selection of the grid frame itself does not meet the requirements, then no matter how much attention is paid to the work, the quality of the finished product is not up to standard. This point should be carefully considered.

       Precautions for processing and welding of grid frame accessories:

       Attention should be paid to the processing and welding process of grid accessories. Before welding, the preparation of welding materials for grid accessories processing should be made. Attention should be paid to the welding mechanism and the preparation amount of welding wire and flux. To do a good job in the baking of welding strips, baking should be carried out according to the quality requirements of grid engineering, and after baking, they should be put into the incubator. Preheating before welding can reduce the cooling rate of the heating zone, and avoid cracks in the welding delay, which will affect the welding effect.

       It should be carried out in accordance with the welding sequence, keep the welding seam gap of grid accessories processing and welding engineering small, and achieve symmetrical welding, longitudinal and horizontal welding. In order to avoid cracks, it is very necessary to do a good job of post weld heat treatment. The holding time is generally determined by 1 h per 25 mm plate thickness according to the plate thickness.
