FIELD: welding by implying pressure. SUBSTANCE: casings and filling material forming a honeycomb structure are placed into a welding chamber with the surfaces to be welded and the casings and compressing members of the rigging being in a spaced relation to each other. The assemblage is heated to a welding temperature using a method for autonomously heating the casings. Then, the heating is stopped and compression is carried out. In this way, the risk of buckling of the casings and compressing members as well as their setting are excluded. Large compressive forces are applicable without destroying filling material in the honeycomb structure. EFFECT: enhanced production capacity and quality of welded joints.
