Abstract
An assembly is formed of thin sheet metal panels, one being of undulating construction, the panels engaging each other in multiple line contact along the apexes of the undulations and the undulations affording a multiplicity of small channels extending through the assembly; the panels are then welded together by a corpuscular beam, preferably an electron beam, that effectively scans a frontal surface of the assembly, the beam being directed essentially parallel to the channels so that weld joints are formed only immediately adjacent the frontal surface.
