The Optimization of Insert Size for Reconstituting Previously Tested Charpy Specimens

Source

The reconstitution of previously tested Charpy impact specimens via projection welding can be used to obtain additional data for nuclear reactor surveillance programs. Typically, a broken Charpy half contains a large portion of untested material. This untested material can be machined from a broken Charpy half to obtain an “insert.” “Endtabs” of similar material can then be welded to the insert. After the welded sample is machined to ASTM E23 specifications, it is then retested to obtain additional toughness data. The materials in this study show that 14 mm inserts can be successfully reconstituted and 10 mm inserts can be reconstituted with limited success.
