J2. GTAW equipment shall be fitted with @ High Frequency starting unit and a crater eliminating slope out control. 3. Tack welding parameters: Same as per root pass. 4. Bridge / Bar materials: Same as per Base metal. Tacking Inside the groove is not allowed. |S. Welds shall not be allowed to cool down until atleast half the wall thickness has been welded 6. Welding shell not be carried out when the degree of protection does not permit satisfactory workmanship, 7. Stray arc shall be avoided. Are Strikes if any shall be ground smooth and grounded area shall be PT tested. 6. The edges and surtaces of parts to be joined shall be prepared by maching or grinding using aluminium oxide grinding discs ‘The cleaned surface shall be extended as least 25mm beyond the weld area 19. Where ever possible, baffles or dams of proper design should be used to conserve the backing gas and to provide effective protection of the weld root. The purge dam should be typically located about 3"on both sides of the welds. 11 backing gas inlet on the dam should be located near the bottom of the pipe &the outlet should be located near the top of the pipe for effective gas backing. H2. Welding shall not be carried out when the degree of protection does not permit satisfactory workmanship. /13.Only SS wire brush and aluminium oxide discs shall be used, PREPARED BY.
