Automig 80S-B2 / Tigfil 80S-B2: Classification: Approvals

This document provides information on Automig 80S-B2 and Tigfil 80S-B2 welding wires, which are copper coated low alloy steel wires for high temperature applications. The wires are suitable for welding low alloy steels used in refineries, petrochemical plants, and fertilizer plants. Precise control of preheat, interpass temperature and post-weld heat treatment is required to prevent cracking. The wires can join similar and dissimilar combinations of Cr-Mo and carbon steels suited for temperatures up to 620°C.
