<p>In a method of manufacturing a glazing panel comprising sheets which are joined together along the margin of the panel using heat-activatable bonding medium (e.g. solder) which is electrically conductive and/or in contact with electrically conductive material and which is activated in situ by induction heating, the induction heating is performed using an inductor 65 powered by an aperiodic generator 57 whose power output setting is determined in dependence on the instantaneous resonant frequency of the inductor circuit as influenced by the load.</p> |
