Why Wire Mesh Fence Surface is Uneven?

In the welding production process, the Wire Mesh Fence screen must be wire drawing, straightening and truncating, then complete welding on the welding machine. In the welding process, we must adjust the current size according to the wire diameter. When the wire diameter reaches 500 wire and the mesh is less than 5cm, the Galvanized Double Wire Fence will appear uneven. In addition, the wear of the welding stigma in the welding process and the change of the force, all will aggravate the poor flatness of the wire mesh fence.
