ABSTRACT:
A welding method controls the welding temperature, welding cycle time, and welding pressure for fabrication of composite structural parts. A welding unit welds multiple plies of thermoplastic prepreg into welded multi-ply assemblies by concentrating welds along the thermoplastic prepreg plies at localized and strategic positions. Two platens weld a plurality of the multi-ply assemblies into a layup using a plurality of heated pins. The heated pins are hollow to reduce surface heating during welding and are non-uniformly shaped to allow indexing of the layup. After the layup is cut into a plurality of thermoplastic prepreg segments along a layup pattern, the thermoplastic prepreg segments are indexed according to the weld marks impressed by the non-uniformly shaped heated pins. The thermoplastic prepreg segments are formed into kits or wedges by stacking smaller thermoplastic prepreg segments on top of larger thermoplastic prepreg segments.
