INERTIA WELDING PM/SX INERTIA WELDING PR REQUESTOR: JOHN GAYDA 433-3273 ITEM: DEVELOP INERTIA WELDING PARAMETERS TO JOIN NICKEL-BASE SINGLE CRYSTAL AND PM DISK ALLOY UTILIZING 10 BLANKS (0.5 DIAMETER X 2 LONG) OF SINGLE CRYSTAL SUPERALLOY WITH (001) ORIENTATION AND 10 BLANKS (0.5 DIAMETER X 3 LONG) OF PM SUPERALLOY LSHR PROVIDED BY NASA. WELD QUALITY SHALL BE EVALUATED USING STANDARD METALLOGRAPHIC INSPECTION AND ROOM TEMPERATURE TENSILE TESTS. AT LEAST ONE DEMONSTRATION WELD WITH DOWNSELECTED PARAMETERS SHALL BE RETURNED TO NASA FOR INDEPENDENT EVALUATION. SOURCE: JERRY GOULD 614-688-5000 EDISON WELDING INSTITUTE 1250 ARTHUR E. ADAMS DRIVE COLUMBUS, OH 43221 WBS: 561581.02.08.03.15.03 PRICE: $10000.00 SOLE SOURCE JUSTIFICATION: AS THIS PROGRAM IS DEVELOPMENTAL AND JOINING OF THESE TWO MATERIALS BY INERTIA WELDING IS NOT COMMERCIALLY AVAILABLE IT IS TO THE GOVERNMENTS BENEFIT TO HAVE THIS EFFORT PERFORMED BY AN ACKNOWELDGED AUTHORITY IN DEVELOPMENT OF JOINING TECHNOLOGIES. EDISON WELDING INSTITUTE IN COLUMBUS, OHIO AND THE WELDING INSTITUE IN THE UK ARE THE ONLY KNOWN QUALIFIED SOURCES TO PERFORM THIS ACTION. AS THE WELDING INSTITUE IS A FOREIGN ENTITY IT IS RECOMMENDED NASA NEGOTIATE SOLELY WITH THE EDISON WELDING INSTITUE.
