Patent ID: 7073700

Claim:
A process for applying brazing material to a metallic structure, which comprises: forming a metallic structure as a honeycomb body having a plurality of individual parts defining passages through which a fluid can flow and passage walls having regions of contact which are to be joined; bringing the metallic structure into contact with a pulverulent brazing material causing the brazing material to at least partially adhere to the metallic structure; vibrating at least the metallic structure at least during the step of bringing the metallic structure into contact with the pulverulent brazing material; and carrying out the vibrating step by holding the metallic structure with at least one of a gripper and a manipulator arm and by transmitting vibration to the metallic structure through at least one of the gripper, the manipulator arm and a pulse emitter emitting a frequency of vibration between 20 Hz and 100 Hz and an amplitude of vibration in a range between 0.1 mm and 3 mm, thereby forcing the brazing material accumulated in the regions of contact of the adjacent passage walls into the regions of contact and being fixed in place.
