  • Packaging and binding electric galvanized wire is in the state of liquid zinc, after messy physical and chemical effects, not only on the steel plating thicker pure zinc layer, and also generate a zinc – iron alloy layer. This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.

  • The coating of electrode plays a very important role in the welding process. If adopting the light of the coated electrode welding, is in the process of welding, oxygen and nitrogen in the air can invade the molten metal, the metal iron and beneficial elements carbon, silicon, manganese oxide and nitride oxide and nitride formation, and remain in the weld, weld slag or crack. And melt into the molten pool in the gas can make the weld produces a large number of pores, these factors can make the mechanical properties of the weld is greatly reduced, at the same time to make the weld brittle.
