ABSTRACT

Welding of Grade 91 (9Cr-1Mo-V) chromium-molybdenum steel has presented numerous challenges since its introduction in the 1980s. One of the principal challenges has been the selection of the optimal welding process. For single-sided-groove welds, the root bead and hot pass(es), are deposited using manual Gas Tungsten-Arc Welding (GTAW) process with an inert gas purge (most commonly argon), followed by another welding process(es) for completion of weld. It goes without saying, that the GTAW process can produce welds of high quality; however, manual welding it is extremely expensive and labor intensive, requiring skilled welders with extreme hand eye coordination and dexterity. Tip Tig has forever change how P91 will be welded for either shop or field fabrication by introducing a semiautomatic GTAW hot wire welding system. Tip Tig’s system is cost effective and can be used for the entire weld from root to cap while producing the high quality weld that the industry expects from the GTAW process.
