SCHWEISSFITTING MIT EINEM SCHWEISSINDIKATOR

摘要

A weld indicator for a weld fitting, comprises a fitting member (24) made of a weldable plastic, and a heating element (28) for producing the weld connection. The indicator is located in a cut-out (22) in the outer surface (30) of the member, and contains a material (6) which undergoes a volume change once a predetermined temperature is reached. The volume change is displayed externally. The indicator is a sleeve or transparent cap, and the cut out is arranged so there is a predetermined spacing between the member and the heater element. The transparent cap contains some free space which can take up part of the expanded material.
