Development Of Overhead Submerged Welding Method

Abstract

Anupam industries ltd. is known for Manufacturing of Large size cranes. The parts of the cranes are very huge and they are joining through the welding. They are using one of welding type ‘submerged arc welding’. Submerged arc welding is not feasible for overhead and vertical welding process. Then it is required to develop overhead welding process for that part which takes more time for adjusting for normal submerge welding operation A method of overhead submerged arc welding consists in that flux at the wing site is pressure-fed to the joint being welded from below at different pressures along the joint being welded, a consumable electrode is fed through the flux from below and an arc is struck. A weld pool is formed thereat with a layer of liquid slag. But in overhead welding there was a defect in the continuous welding. We are reached only up to the spot joint in over head. And in the vertical submerged arc welding change the movable torch position tilt it at 90o and the make one box which from non conductive material for the storage of the flux. And change the moving position of the tractor horizontal to vertical. With the small diameter wire with low current can weld on the vertical position.
