摘要 |
Two plastic components, partic. pipes, are held coaxially in a jig for butt-welding. The component ends are heated without contact by an electrically heated plate (13) which has a ceramic coating (14). The plate (13) can be of copper or steel and have several cartridge heaters (15) and a temperature sensor (16). The thickness of the ceramic coating (14) can be 0.1-0.6 mm. There can be a thin layer of Ni between a Cu plate (13) and the ceramic coating (14). Pref. a frame (3) has a fixed clamp (4) holding a pipe (1) and a movable clamp (5) for a component (2) which is brought into the required position. The heating arrangement (7) can be swung into position with a handle (9) on a spring loaded lever (8). The heater (12) has stops (17) which allow it to be lined up accurately. A gauge (19) and cutter (20) are used to machine the required weld preparation. |
