Abstract
A method for tempering steel for riveting includes positioning a first component having a first composition over a second component having a second composition, and resistance spot welding the first component to the second component using a resistance spot weld gun to form a spot weld. The method includes tempering at least one of the first component, the second component and the spot weld with the resistance spot weld gun, and coupling a third component having a third composition to the first component and the second component with a rivet, and the third composition is different than the first composition and the second composition.

A method of riveting, comprising:
- positioning a first component having a first composition over a second component having a second composition, the first composition different than the second composition;
- resistance spot welding the first component to the second component using a resistance spot weld gun to form a spot weld;
- after the resistance spot welding, tempering at least one of the first component, the second component and the spot weld with the resistance spot weld gun to soften at least the second component;
- and
- after the tempering, coupling a third component having a third composition to the first component and the second component with a rivet inserted through the spot weld, and the third composition is different than the first composition and the second composition.
