Abstract
Methods and apparatus are described for producing welded assemblies of plastic parts for use in fluid flow applications. A unit cell structure is disclosed for use in an assembly. In an exemplary embodiment, an assembly of welded plastic parts for a fluid flow application includes a plurality of as-molded plastic unit cell structures, each cell structure having a hollow tubular body portion, a first tubular portion extending axially from a first end of the tubular body portion, and second and third opposed transverse tubular portions extending from an intermediate portion of the tubular body portion transverse to the first tubular portion. The first tubular portion of a first unit cell structure is welded to the first tubular body portion of a second unit cell structure in an axially aligned configuration.
