Abstract
An arrangement for butt-welding tubular plastic components includes two chucking devices for holding the components in coaxial positions relative to each other and a heating device for heating the ends of the components without contact. The heating device includes a heating element which can be swung between the two chucking devices. The heating element heats the ends of the components without contact by heat rays. The heating element includes a metal plate which is coated with a ceramic coating and which is electrically heatable by heating cartridges.
