An electric heating element having a central conductor 10 and an outer metallic sheath 11 is welded to a base 13 of vessel 12 to provide a heating container, for hot water in a domestic appliance for example. In order to carry out the welding, the vessel 12 is heated up by an induction heater 14 to a certain temperature and the temperature of the actual contacting welding surfaces raised above the certain temperature to a fusing temperature by applying and controlling electric power supplied to the conductor 10 while the heating element is held firmly in position against the base 13. <IMAGE> |
