Abstract
A process of connecting a header pipe of a heat exchanger to another heat exchanger part, including the steps of (a) providing a header pipe with a hole in its side and cladding material about its circumference, and a part with a groove with flux applied to the portion of the part to be joined to the header pipe, (b) positioning the header pipe and the part to align the header pipe hole and part groove, (c) inserting a rivet into the aligned header pipe hole and part groove, (d) locating a supporting rod in the header pipe and aligned with the rivet, and (e) hammering the part to warp the head of the rivet against the supporting rod and widen the circumference of the rivet in the hole and groove.
