In the swell-welding according to the invention of two bodies, of which at least one body consists of plastic, the connection surface of the plastic body is firstly exposed to a gas which contains the vapor of a swelling agent for the plastic. The plastic body reversibly swollen at the surface is welded to the other body by pressing onto one another, and the pressed-together bodies are conditioned. In all process steps, the temperature of the bodies to be connected is below the glass transition temperature of the plastic. No auxiliary substance remains in the welded body. The flush connection produced by swell welding is durable and strong.
