Welding electrode consists of two parts, the core and coating. Metal welding rod core in the outer coating (coating) uniformly applied to the heart of the low-pressure core welding, welding different types, different welding core, Welding electrode core metal core, in order to ensure the quality and performance of the weld, butt content of the core elements of various metals have strict rules, especially for the content of harmful impurities (such as sulfur, phosphorus, etc.), there should be strict limits, than the base metal. Welding core component directly affects the composition and properties of the weld metal, so the welding core of harmful elements as little as possible.

Welding carbon steel and low alloy steel welding core, generally used as a low-carbon steel welding core and add manganese, silicon, Ge and other ingredients (see wire national standards GB1300-77) using one hand, the reasons for the low carbon carbonaceous low amount of steel wire plastic, wire drawing easier, on the other hand can reduce the CO content of reducing gas to reduce splashing or pores, and can increase the temperature of the weld metal solidification, for overhead welding favorable.

Joined other major alloying elements to ensure the mechanical properties of the weld, while welding performance and impurities, also have a role. High-alloy steel and other metals as aluminum, copper, cast iron, etc., in addition to its core component welding requirements are similar to weld metal, the same should also control the content of impurities, according to process requirements often adding certain alloying elements
