The method also includes driving a rivet into the target location, optionally with a driver, after locally melting the target location such that the rivet pierces the at least two metal substrates at the target location.
A bottom forming system for a metal container includes a domer assembly that forms a double dome in a bottom of the metal container during a bottom forming process. The domer assembly includes a first domer and a second domer that is movable relative to the first domer. A method of forming a bottom of a metal container includes forming a first dome profile in the bottom of the metal container using the first domer and the second domer of a domer assembly. The method includes forming a second dome profile in the bottom of the metal container by moving the second domer relative to the first domer.

SURFACE TREATMENT OF METAL SUBSTRATES SIMULTANEOUS WITH SOLUTION HEAT TREATMENT OR CONTINUOUS ANNEALING
Methods and metal products are described for simultaneously performing a solution heat treatment operation or continuous annealing operation and surface treatment operation using super-heated steam to produce a processed metal product. An elongated metal substrate can be subjected to a solution heat treatment operation or a continuous annealing operation. Additionally, the elongated metal substrate can be subjected to a surface treatment operation. The solution heat treatment operation or continuous annealing operation and the surface treatment operation can be performed simultaneously using super-heated steam to produce the processed metal product.
