Mucci, J.

Machining of the A106B GTA and EB welded specimens was completed. Laser welding of the AISI 304L and ASTM A106B materials is continuing. Tensile testing of the ASTM A106B EB welded specimens was initiated and completed. Testing of the ASTM A106B EB welded material indicated generally lower ductility than the parent material. Low-cycle fatigue testing of the ASTM A106B material in 13.8 MPa hydrogen indicates reductions in mean life of approximately 50 and 27% due to the GTA and EB welding respectively. (LK)
