A method and apparatus for producing highly effective head exchanger elements of the type which comprise corrugated surface enlarging members of strip material fixed to thin walled substrates. The strip material which can be either pre-corrugated or corrugated synchronously with the heat exchanger element manufacturing process is advanced concurrently with a substrate material to a station at which the strip is lightly held in firm abutment with the substrate material by means of an impinging stream of gaseous medium and simultaneously metallurgically bonded to the substrate. The composite product is then cut into lengths to form finished heat exchanger elements.
