ABSTRACT:
To improve the strength of the laser weld bond between an inner honeycomb column and an outer metal case, a metal honeycomb assembly comprises a metal honeycomb column composed of a flat metal sheet and a wavy metal sheet which are mutually laminated and spirally wound together, the metal honeycomb column having an outermost circumferential portion in the form of a composite wavy sheet composed of a plurality of superposed layers of the wavy metal sheet; and a metal case fittingly enclosing the metal honeycomb column, the metal case and the metal honeycomb column being bonded together by laser-welding the wave peaks of the composite wavy sheet to an inner wall of the metal case.
