Abstract: A titanium gas injection tube (18) is located within a counterbore (16) in the blade (10) halves which are to be bonded and formed. An internal stainless steel sleeve (24) is placed in the counterbore inside the titanium tube to resist bonding forces. An external stainless steel sleeve (28) is placed around the tube to resist gas pressure forces.
