Abstract
A pressurized vessel, such as a tank liner, is formed of a thermoplastic injection-molded connector or insert and a thermoplastic blow-molded vessel body. A noncylindrical skirt of the connector having a substantial surface area is spin-welded to a mating interface formed on the outer surface of the vessel body adjacent an orifice into which the insert is received. In a preferred embodiment, a sacrificed portion of an upstanding orifice sidewall forms a molten weld bead, which flows in a channel to fuse the skirt to the mating interface.
