There are many quality parameters of welding mesh products, such as wire diameter, mesh size, plastic coating material, plastic back wire diameter, Dutch column wall thickness, etc., but when buying, as long as you master the following two parameters: weight and plastic coating. The net weight of electric welding mesh includes two aspects: the net weight of electric welding mesh and the net column weight of electric welding mesh. In procurement, the two are accounted for separately, so to understand the net amount of galvanized welding mesh is how much, the number of welding mesh, to understand these, even if the manufacturer has more means, there is no place to escape.
Welding net weight, net height is different, the natural weight is different, and each part of the weight is divided again to distinguish different qualities. Of course, depending on the warp and weft used and the plastic powder, this value fluctuates from the top to the bottom. The weight of the welding mesh is determined by the thickness of the welding mesh. There are several heights. Galvanized electric welding net surface spray plastic. There is only one type with no quality difference. Welding mesh coating, plastic coating refers to the surface of a layer of plastic material, there is no difference in quality, but the addition is different after production, there is no hard plastic welding mesh production, add a small amount of production of low bubble welding mesh, the amount of addition, followed by the production of general foam welding mesh and high bubble welding mesh.
If the eyes look past, if there is gloss, it is hard plastic, no gloss is foam plastic; Touch with the hand, it feels smooth like a mirror is not astringent, especially hard, so it is hard plastic, if it feels astringent and slightly elastic, it is low foam, if it is astringent and elastic, it is medium foam, but if it feels particularly soft, like touching the belt is generally high foam, there is no doubt.
Working principle: When welding, the match is lit, which causes the welding flux to burn and release a lot of heat to heat and melt the welded base metal locally, and the generated metal product is used as the weld filler to form a welded joint after solidification to achieve a solid connection of the base metal. Function: The electrode is composed of two parts: the welding core and the coating. The welding rod is applied uniformly and centrally to the metal core. Different types of electrode, welding core is also different. 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, especially on the content of harmful impurities, there should be strict restrictions, which is better than the base material. The metal core in the electrode covered by the coating is called the welding core. The weld core is generally a steel wire with a certain length and diameter.
