eletrodo revestido
What is eletrodo revestido?
Eletrodo revestido, also known as shielded metal arc welding (SMAW) or stick welding, is a manual arc welding process that uses a consumable electrode covered in a flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. The workpiece and the electrode melts forming a molten pool that cools to form a joint. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination. It is commonly used for joining steel, stainless steel, cast iron, and some nonferrous metals in various industries like construction, shipbuilding, and repair work due to its versatility and relatively low equipment cost.
