摘要：A bonding material (S), especially a thermoplastic, is heated, melting it. Two workpieces (K1, K2) of higher melting point are pressed together such that the bonding material penetrates into recesses (V) formed in the workpieces. On cooling, the bonding material connects the workpieces, producing an interlocking interference bond. At least one workpiece is heated for the purpose. At the locations to be joined, the workpieces include undercut recesses allowing penetration of the material. The recesses alternatively have internal surface structure or texture, facilitating bonding.
