The electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core. Electrode structure: portable non – electrode, including cylinder, tube, sleeve plug. The electrode is made of metal or metal oxide powder, such as high heat agent and additives. Paper tube is generally used for drug pipe, and metal tube can also be used for different welding parts and use environment. The plug is at the end of the electrode, which is the clamping part that matches the sleeve during welding and prevents the flux from leaking out of the tube.

Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

Thorn rope factory production per ton of product profit is not particularly high so in the sales price to wholesale, many users always think that thorn rope price has a lot of profit space so they are eager to lower the price, some manufacturers in order to sell out on the use of low price promise and then underweight behavior. Often the actual user spends less money with the lack of weight is almost the same, so the unit price is relatively high. Because the quotations of the thorn rope factory are in accordance with the real price, the quality is guaranteed. In this way, the customers will not look for debts after the purchase, and the subsequent purchase work will still find us, so that we can benefit.

The physical methods mainly include manual rust removal and mechanical rust removal, chemical rust removal is generally the use of pickling method, practical application, usually according to the appearance of the workpiece rust status and different post-treatment process, choose different rust removal methods, among which pickling rust cleaning is more commonly used. That is, the iron and steel workpiece with oxide skin or rust is etched in the acid lotion, mainly to remove the oxide or rust layer on the surface of the steel.
