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.
