METHOD TO EXECUTE A WELD OF AN ELECTRODE OF A CELL WHICH IS PART OF A BATTERY

A method to execute a weld of an electrode of a cell which is part of a battery and having the steps of: causing the electrode to come into contact with another element to which the electrode must be welded; locally heating the electrode and the other element so as to locally cause a melting of the metal making up the electrode and of the metal making up the other element in order to generate a weld pool; waiting for the weld pool to cool down, thus giving stability to the weld; capturing, by means of a video camera, a series of digital images of the weld pool during the heating; analysing the digital images in order to determine a value of at least one parameter of the welding process; and changing the execution of the melting process based on the value of the parameter.
