Unlike conventional 2.25Cr-1Mo filler wires classified as AWS A5.28 ER90S-B3, TGS-2CM is classified necessarily as ER90S-G due to its unique chemical composition. As shown in Table 1, TGS-2CM weld metal contains comparatively less silicon (Si) compared with conventional ER90S-B3 wires. In addition, TGS-2CM restricts phosphorous (P), antimony (Sb), tin (Sn), and arsenic (As). This elaborate chemical composition minimizes temper embrittlement (Fig. 1) and improves resistance to hot cracking that is likely to occur in root-pass welding of tubes and pipes. Figure 2. An example of automatic GTAW application for joining the 90-degree bend and flange extended from the bottom head of a reactor pressure vessel. TGS-2CM is available in both cut rod and spooled wire. The spooled wire is for mechanized gas tungsten arc welding. Bend-to-flange joints of reactors, Tube-to-tubesheet joints of heat exchangers and pipe-to-pipe joints of process piping are typical applications for the automatic GTAW.
