Abstract

Thermoplastic resin parts are opposingly placed from each other and a concentrated blast of hot air is applied to opposite areas of these parts to be welded while the parts are rotating. After melting the opposing areas of these parts by application of the hot air thereto, the parts are then forced into integral contact with each other.
