It is not strange to mention the protection network, it is mainly used in highway, railway construction and other aspects, is processed by many processes. Now let's look at the welding process.

Guardrail welding before the first choice of high-quality materials, here is the beginning of the welding process, raw materials in the way of wire rod placement, the number of wire rod is determined by the size of the silk products.
The styles of the rod are ordinary and threaded shapes, customized according to the customer's appearance requirements. The wire rod is cut through the pre-straight wire, and the next step is welding. The welding of the protective net is organized and produced in accordance with the standard FHB/Q1268.
What do you need to pay attention to?
Welding is a process of rapid local heating and cooling. Before welding, the stepper motor controller is driven for accurate positioning and rotation according to the set direction. The welding equipment is heated according to the thickness of the wire. When the current passes through the connecting end of the two iron wires, the temperature rises because of the large resistance. When it is heated to the plastic state, it is connected as a whole under the action of axial pressure. The welding area cannot expand and contract freely due to the constraint of the surrounding iron wire body, and welding deformation occurs in the welds after cooling.
