By metal welding rod core and the outside painted in thick coating composition. Coating thickness and composition of the various decisions of the different operating processes. Electrode composition and thickness of the coating, the current type and determines the polarity of the electrode clamp as well as the shape of the droplet. Length of the rod in between **0 ~ **0mm. Some by welding metal into control, metal tube containing powder mixture. The role of coating ①coating the main role is to provide protection for the pool atmosphere, so as not to suffer in the air of oxygen, hydrogen and nitrogen pollution, until coagulation bath. ② the provision of clean agent, agent-agent slag making, in order to purify and to prevent the weld seam metal in the grain grown up too much. ③ arc to provide chemical substances in order to control the electrical characteristics of arc welding. ④ formed in the weld slag coverage, the delay of the weld metal cooling rate, the protection of cooling in the weld metal from air pollution, but also controls the shape of the droplet. ⑤ to the pool of alloying elements added to enhance the mechanical properties of weld metal. The electrode is commonly used size length **0mm, Core diameter welded to the general: 1.6mm, 2.0mm, 2.5mm, 4.0mm, 5.0mm, 3.2mm, Electrode coating the relative humidity should normally be less than *0% of the welding rod to prevent the damp container used for sealing metal cans or cartons.
