A method and apparatus for forming a honeycomb structure (22) in which a plurality of thermoplastic layers (12, 14, 16, 18 and 20) are fused together at selected locations (24). The thermoplastic layers (12, 14, 16, 18 and 20) at each of the selected locations (24) are melted together to form a welded portion which includes first and second exterior surfaces. The welding of the thermoplastic layers (12, 14, 16, 18 and 20) is controlled so that no more than one of the exterior surfaces is melted. This partial melting of one layer prevents undesirable welding to adjacent layers. An apparatus (30) for carrying out the method for welding thermoplastic honeycomb structures is also disclosed. |
