Abstract Aiming at alloys commonly used in terminals, this paper studies the method of improving characterization performance spot welding section from perspective controlling process parameters. Using control experiment, by current, energization time, electrode pressure, and using coolant during welding, surface structure image maximum tensile-shear force curve were obtained, so as to obtain o...
