Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.

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.
