ABSTRACT:
A method for fixing an element to a part of an electrical apparatus may include interposing an extender between the element and the part, where the extender is able to exert forces on the element and the part to position the element with respect to the part and/or to secure the element in position with respect to the part, by friction between one side of the extender and the element and between another side of the extender and the part, and to ensure positioning and/or securing of the element with respect to the part prior to final fixing, and to perform final fixing by performing two welding operations respectively between the element and the extender and between the extender and the part.
