Optimización del proceso RSW para acero DP 1000

ABSTRACT In recent times new materials have been introduced in automobiles construction in order to reduce their weight and consequently fuel consumption and emissions level. Among them are Dual Phase (DP) steels, constituted by a ferritic matrix with martensite islands. Resistance Spot Welding (RSW) is the most commonly used welding process in the automotive industry. However, the welding of these materials presents greater challenges, since the parameters used for RSW welding of conventional steels are not applicable on these advanced steels. Also, the welding thermal cycle degraded its prop...
