How many welding methods are there for stadium fencing

The stadium fence is a new type of protective product designed specifically for stadiums. This product has a high net body and strong anti-climbing ability. The stadium guardrail net is a kind of site fence, it is also called: "sports fence", it can be installed on-site construction fence posts and fences, the biggest feature of the product is its strong flexibility. How many welding methods are there for stadium fences? 1. When welding and cutting carbon steel, the flame should be selected mainly according to the carbon content of the steel. Carburizing flame cannot be used for welding medium and low carbon steel, as the high temperature liquid metal scraps will absorb the carbon particles in the flame, causing the weld metal to Increase carbon and reduce the mechanical properties of the weld. When welding high-carbon steel, cast iron and other metals, due to excessive carbon burning, a carburizing flame is required to prevent decarburization. If the flame is not well controlled and changes occur during the welding process, the quality of gas welding and gas cutting will be reduced. 2. Spot welding technology is currently the most popular welding method for fences. In welding, the arc welding power source uses the heat generated by the welding arc to melt the welding rod and electrical equipment. Main principle: The resistance value of the welding arc is constantly changing and changes with the change of arc length. When the arc length increases, the resistance increases and the curvature decreases. 3. Oxidizing flame: Due to its high oxidizing property, it is easy to gasify the molten metal and burn the alloy elements, resulting in defects such as weld porosity, slag inclusion, and reduced mechanical properties. Therefore, it is not suitable to use oxidizing flame for welding metal leaves of stadium fence. The same is true for other non-ferrous metals. The flame properties must be strictly controlled to prevent the burning of alloy elements and the reduction of mechanical properties.
