ABSTRACT:
A TIG weld produced from a rapidly solidified dispersion strengthened aluminum base alloy exhibits attributes of the alloy's microstructure extant prior to formation of the weld. TIG welding power is adjusted to minimize energy input into the weld. An arc gas contacts the weld to maximize rapid quenching thereof, while a second gas contacts the undersurface of the weld so that the undersurface of the weld is quenched. Cooling of the weld is further enhanced by a trailing gas selected from the group consisting of argon, nitrogen, helium, carbon dioxide and mixtures thereof.
