What are the welding electrodes?
Not a single electrode metal material, which is composed of a metal core and coating. The electrodes of each model are different in composition.The electrode consists of two cores and coating composition. The electrode is coating in metal welding core (coating), uniform centripetal pressure applied to core. The electrode of different types, different cores. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal. The electrode is metal cored coating called cores. The core is generally a certain length and diameter of the steel wire.When welding, welding core has two functions:One is to conduct welding current, which generates electric arc and converts electric energy into heat energy;The two is the core melting as the formation of the weld filler metal and liquid base metal fusion.
The utility model relates to an electric welding rod, which belongs to hardware engineering consumption equipment. Welding rod is listed as "manufacturing industry" in the industry classification standard of People's Republic of China: other metal products are manufactured.Brief introduction of electric welding strip:The electrode consists of two cores and coating composition. The electrode is coating in metal welding core (coating), uniform centripetal pressure applied to core. The electrode of different types, different cores. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal.
