In the thorn rope manufacturer, there are also great differences between hot galvanized thorn rope and cold galvanized thorn rope.

The welding process of galvanized steel wire mesh because of low carbon steel carbon content is low, manganese and silicon content is low, will not occur severe hardening or quenching structure due to welding. The low carbon steel joints have excellent plasticity and impact toughness after welding. In the welding process, it is generally not necessary to preheat, interlayer temperature control, post-heating control and heat treatment to improve the welding structure.

The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.

There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.
