Abstract
A hot air blast welding apparatus for welding works of thermoplastic materials having different softening temperatures. The apparatus includes a nozzle having nozzle openings for applying hot blasts of air to respective ones of the works. The nozzle is so constructed that it applies air blasts of different temperatures or different flow rates to the works so that the works are brought substantially simultaneously to softening points.
