Bonding technique
Abstract
Abstract The invention contemplates a bonded assembly of plural parts having regions o channel-socket or telescoping fir with each other. One or more small apertures are provided to vent the overlap region of such fit, and the apertures assists in the pressurized liquid-phase introduction of hardenable bonding material. Depending upon the nature of the assembly or joint, (a) the parts may be fabricated to naturally and substantially close or dam the open annulus attributable to clearance between the overlapped parts at the open end of the region of overlap, or (b) expendable rings or solid plugs may be used to confine to the overlap region the flow of injected bonding material. After such injection and flow, the bonding material is cured to hardness.
