GTAW ROOT PASS WELDING OF 6% MOLYBDENUM AUSTENITIC STAINLESS STEEL PIPE - OPEN ROOT JOINT WITH HAND-FED FILLER

Much useful attention has been given to overcoming the corrosion problem encountered in the root bead of a 6% molybdenum austenitic stainless steel pipe weld

• Sound procedures have been developed and reported for orbital welds with consumable inserts and for manual GTAW welds with consumable inserts.
• This TIP provides guidelines for making a corrosion-resistant root pass using GTAW and hand-fed filler metal.
• The TIP is intended to be used as a guide in establishing welding procedures and acceptance criteria, not as a specification.
• This TIP contains guidelines for the open root joint welding of 6% molybdenum austenitic stainless steel pipe with the gas tungsten arc welding (GTAW) process and hand-fed filler metal.
