Welding of Austenitic Stainless Steel - Part 2 - TWI

Welding consumables must also be selected with low carbon content if best corrosion resistance is required. Most arc welding consumables contain less than 0.03% carbon but there are filler metals available with carbon contents of up to 0.10%; these should only be used to weld the 'H' grades of steel where good creep resistance is required.SPECIFICATION FOR PIPEWORK WELDING, INSPECTION, Proper Back-Up Gas Pressure Weld Defects Weld Repairs SPECIFICATION FOR STAINLESS STEEL PIPE ORBITAL WELDING Scope General Requirements Welding Procedures and Qualifications Weld Joint Preparation and Fit-Up Tacking Welding Equipment Shielding Inspection Tube Sections Verification Cleaning Verification Joint Fit Up
