keevituspulgad
Keevituspulgad, also known as welding electrodes or welding rods, are essential consumables used in shielded metal arc welding (SMAW), also called stick welding. They consist of a metallic core wire coated with a flux. The core wire acts as the electrode, delivering the welding current and melting to form the weld metal. The flux coating serves multiple crucial purposes. It stabilizes the arc, shielding the molten weld pool from atmospheric contamination like oxygen and nitrogen, which can weaken the weld. Additionally, the flux decomposes to produce shielding gases and slag, which further protects the molten metal and can influence the weld bead's appearance and properties.
Different types of keevituspulgad are available, categorized by their core wire composition and flux coating. These
