    INVESTIGATION ON PORE FORMATION IN LAP JOINTED ELECTRON BEAM WELDED CUCRZR BASED ALLOYS
    Disha Chaudhari*, M N Patel

    The precipitation hardened CuCrZr alloy is used in fusion machines for the heat sink of intensely cooled plasma facing components (PFC) due to its good thermal and mechanical properties. CuCrZr is a precipitation hardened alloy and its optimal strength is obtained in Solution Annealed (SA) at 980°C + water quenching + Aging (A) at ~480°C, 3 hr, Electron Beam Welding (EBW) is employed. In this paper, investigation on pore formation after EBW of Lap jointed CuCrZr heat flux alloys was carried out. Ground pores are said to be commonly observed in welding of CuCrZr alloys. The extent of ground pores seems to be depends upon welding configuration, impurities in the material, depth of penetration etc. LECO test results reveals that oxygen content mainly observed in weld region, chances of oxides formation is increased near defect zone. Average oxygen content observed in weld region was higher.
