Saw Hardfacing (Submerged Arc Welding)

Arcraft Plasma Equipments (I) Pvt Ltd has developed SAW Hardfacing (Submerged Arc Welding) process. Submerged arc welding is a semi-automatic or fully automatic consumable electrode arc process in which the arc is protected by a granular, fusible flux which blankets the weld puddle and surrounds the base metal to protect it from the atmosphere. Powder alloys can be added with the flux. This utilises the existing bead produced by SAW to melt powders and thereby increase deposition rates. The flux stabilises the arc, provides slag coverage, and also controls the properties of the deposit. Consumables are in the form of wire or strips. High deposition rates using current up to 2000 A in AC or DC mode, deep penetration, easy slag removal and smooth and excellent quality welds are common with this process. SAW is a highly productive process for surfacing large areas. Fully automatic systems are used for heavy depositions in various areas such as surfacing continuous casting rolls, blast furnace bells, forging die block, inside of ball mill shell, etc. The company also offers Welding Inverter, Welding machine - AC-DC 2540/T, TIG welding machine, Welding Machine, Micro-Tig, etc.
