Abstract
A process for producing a heating plate involves fastening a tubular heating element (1) to a plate (2) made of metal or metal alloy. A plate (2) made of rolled metal or metal alloy is used, and cold-stamped in this plate is a shoulder (3), the contour of which corresponds substantially to the contour of the tubular heating element (1). The tubular heating element (1) is placed against the shoulder (3) and fastened to the plate by soldering. The thickness of the central part of the plate (2) is sufficient to withstand the thermal stresses which it must undergo. The process is especially useful for producing a heating sole of a steam-operated smoothing iron.
