3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

Galvanized wire for welding is generally required to have a certain hardness, after acceptance of galvanized wire, feel is the first thing to do, in addition to the machine test, because the average user does not have testing equipment, on the machine trial is also a very inconvenient way to test. The diameter of electric galvanized wire is measured with a micrometer, and it is kept at about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no messy wire.

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.

The wire rod should be normalized or soxhlet processed, instead of spheroidal annealing for standard large ones. Soxhlet process is widely used in the heat treatment of the center, especially the products before drawing. Avoid decarbonization during heat treatment. After heat treatment, sulfuric acid or hydrochloric acid pickling is used to remove iron sheet. The coating (see smooth carrier) can be dip-lime, phosphating, borax treatment or copper plating.
