摘要
A hot isostatic pressing tool (50) comprises a plurality of canister members (52, 54, 56, 58) and the hot isostatic pressing tool (50) comprising at least one set of adjacent canister members (52, 54, 56, 58). The plurality of canister members (52, 54, 56, 58) form a chamber (59) to receive a powder material (61) to be hot isostatically pressed. The at least one set of adjacent canister members (52, 54, 56, 58) have interlocking features (60, 62, 64, 66, 68, 70, 72, 74) forming a U-shaped, or a Z-shaped, leakage flow path between the at least one set of adjacent second canister members (52, 54, 56, 58). The adjacent canister members (52, 54, 56, 48) are welded (84, 86, 88, 90) together to form a joint and the U-shaped, or Z-shaped, leakage flow path reduces the likelihood of failure of the welded joint during hot isostatic pressing.
