Abstract
A method and apparatus for forming a honeycomb structure in which a plurality of thermoplastic layers are fused together at selected locations. The thermoplastic layers at each of the selected locations are melted together to form a welded portion which includes first and second exterior surfaces. The welding of the thermoplastic layers 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 for carrying out the method for welding thermoplastic honeycomb structures is also disclosed.
