In welding, proper consumables or fillers are used to ensure a firm bond between the two metals. It is one of the four parts of welding, welding metal, heat source and air shielding. When the metal is heated to its melting point and isolated from the air, consumables are added to the connected area to produce a single metal. The role of arc extinguisher in arc welding is not only to fill seams, but also to stabilize the flame of arc. According to the working conditions, the types of consumables used can vary between the core wire, solid wire or rod electrode. Electrodes absorb the necessary energy to perform welding applications.So how to choose welding consumables suppliers?

Three different types of electrodes are used in some of the most common welding processes.(1) Powder coated electrodes are used in shielded metal arc welding. When it burns off, the coating can protect the weld from the influence of oxygen. Filling metal is usually added to the coating to speed up the process.

(2) Gas shielded tungsten arc welding uses non-expendable tungsten bars to heat and fill metals. The rod only heats the metal and will not be added to the filling material.(3) Gas shielded metal arc welding is a process of using consumables of welding wire, in which the wire is fed into the welding joint.
