The electrode force, weld current, and weld time are three essential parameters of the resistance spot welding process. This paper deals with the characterization and understanding the effect of weld time and the influence of different weld atmospheres in the resistance spot weldability of AISI304 grade stainless steel deformed in tension by 5%, 10%. or 20%. Therefore, the microstructure of the weldment was evaluated and the hardness and tensile shear load bearing capacity of weldment were also determined. It was found that the final mechanical properties of weldment are directly related to the parameters of the process used, knowing the weld time and rate of deformation prior to welding.
