Abstract
The metal housings of multi-branched plastic lined components are welded in situ with the liner in place. A series of grooves in the outer surface of the preformed plastic liner underlie the weld joints and, in cooperation with a vent passage, prevent blow-out of the weld metal and damage to the plastic, all at higher welding temperatures sufficient to obtain deeper weld penetration.
