The present disclosure discloses a button cell, and a method for welding electrode tabs to a pole shell of the button cell. The button cell includes the pole shell and an electric core. The pole shell consists of an anode shell and a cathode shell. The button cell further comprises at least one metal sheet. A cathode tab and/or an anode tab of the electric core is/are welded to the metal sheet, and the metal sheet is then welded to the cathode shell and/or the anode shell. The button cell manufactured by the invention has a complete surface, and can avoid phenomena such as electrolyte leakage and surface bulging caused by the rupture of the polar shell.

An article comprising additively manufactured metal portions is described. The article comprises a first additively manufactured metal portion, and a second additively manufactured metal portion coupled to the first additively manufactured metal portion at a welded joint. The article further comprises a resistive heating material disposed within an interior of the welded joint, the resistive heating material comprising a different material than the first additively manufactured metal portion and the second additively manufactured metal portion.

A welded assembly includes a first object, a second object, and an interlayer. The interlayer is an ESD coating deposited on the first object, and the second object is welded to the coating. The second object may be a material that has thermally sensitive properties, such as a shape-memory material. The second weld may also be made by ESD. The interlayer may be made of more than one layer. The layer or layers may be deposited of a material chosen for its compatibility with one, the other, or both of the material of the first object and the material of the second object.
