How to detect the processing quality of grid frame accessories?

The processing of grid accessories may seem simple, but it is not simple either, because the quality of the accessories directly affects the quality of the grid. If you want to use the grid with confidence, we need to increase efforts in the processing of grid accessories. Once the accessories are processed, we also need to conduct quality testing. So how should we detect them?

Quality inspection of grid frame accessories processing:

Firstly, there are very direct requirements for the welding skills of the processors. Although it is difficult to see whether the grid welding is good or not, the accuracy of the welding and the overall deformation of the grid are closely related to technology. To have a high-quality grid, one must have a high-quality craftsmanship.

Secondly, we can also take a look at the entire production process of grid accessories. Different processing methods have different angles and sequences for the entire grid production. Usually, from the sequence, we can distinguish which is more professional and which is more layman, and then we can find the side with more reliable technology.

Thirdly, it is also important to choose and master the materials for the grid structure. If the material selection of the grid structure itself does not meet the requirements, no matter how much effort is put into the workmanship, the quality of the finished products produced will not be satisfactory. This should also be carefully considered by everyone.

Precautions for processing and welding of grid frame accessories:

Attention should be paid to the processing and welding process of the grid components. Before welding, preparations should be made for the processing and welding materials of the grid components, and attention should be paid to the welding mechanism and the preparation amount of welding wires and flux. To do a good job in baking the welding strips, they should be baked according to the quality requirements of the grid project, and after baking, they should be placed in an insulation box. Preheating before welding can reduce the cooling rate of the heating zone, avoid welding delays and cracks, and affect the welding effect.

It is necessary to follow the welding sequence to maintain a small weld gap in the processing and welding engineering of grid components, and achieve symmetrical welding, longitudinal and transverse welding. It is necessary to perform post weld heat treatment to avoid cracks. The insulation time is generally determined based on the thickness of the plate and is 1 hour per 25mm of plate thickness.
