An automotive engineer wishes to improve the burst pressure of radiator for the next generation
of vehicle. The engineer focuses on the brazing process used to join the aluminum radiator
components together. The engineer runs an experiment in which radiators are fabricated using
three different types of filler (1, 2,3) material and two different brands of flux (A, B). The flux
prepared the surfaces to be joined and protects them from oxidation while the filler material joins
the components. The radiators are brazed in an oven at the same temperature setting. The oven
holds twelve radiators so two of each treatment combination are used.
