annealed iron wireWire-wall welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold. The coating on the surface of the weld core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.

Post time: 14-07-22Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion. Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
This method is generally the use of hot rolled laminated plate as raw material, the annealed steel plate is first sent to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the steel sheet oxygen hot galvanizing method. After pickling, the steel plate immediately enters the tank to soak and wait for galvanized, which can prevent the reoxidation of the steel plate. After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.
The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
