Abstract
The present disclosure concerns a spot welding method, including the following steps of: arranging two electrically conductive parts to be assembled between two electrodes, each of the two parts having an interface zone between the two parts and a contact zone with one of the two electrodes; establishing a first electric current between the two electrodes through the two parts, the first electric current producing thermal energy capable of forming a weld nugget within the two parts; and adjusting a distribution of the thermal energy density produced by the first electric current based on the intrinsic characteristics of each of the two parts, to generate a weld nugget initiation zone at a selected depth in the parts to be assembled.

A spot welding method, comprising the steps of:
- arranging two electrically conductive parts to be assembled between two electrodes each of the two electrically conductive parts having an interface zone between the two electrically conductive parts and a contact zone with one of the two electrodes, and
- establishing a first electric current between the two electrodes through the two electrically conductive parts, the first electric current producing thermal energy capable of forming a weld nugget within the two electrically conductive parts, and
- adjusting a distribution of thermal energy density produced by the first electric current based on intrinsic characteristics of each of the two electrically conductive parts, to generate a weld nugget initiation zone, at a selected depth in the two electrically conductive parts to be assembled, adjusting a resistivity differential of the two electrodes comprising covering of the contact zone of one of the two electrodes with a fixed layer or a removable layer, made of a material having a resistivity that makes it possible to obtain the adjusted resistivity differential.
