## Abstract
Abstract Resistance spot welding plays an important role in the automotive industry for working on car bodies or frames. Welding with two different steel materials is used in automotive structures. However, the low strength of the joints of different steel materials is a major problem, limiting the scope of its application. The quality of the welding connection Resistance spot welding is influenced by several factors, namely, time, welding current, and electrode pressure applied during welding and post-welding treatment. In this research, mild steel plate with AISI 304 stainless steel is welded by Resistance spot welding with different variations of welding time, material hardness and tensile testing that will be investigated. The results showed that the highest Rockwell Hardness time was obtained at a welding time variation of 8 seconds with a current of 6000 Ampere was 112.2 so the higher the welding time, the higher the hardness obtained. welding 8 seconds with a welding current of 6000 Ampere obtained a maximum tensile strength of 20.4 kgf/mm 2 so the greater the welding current, the tensile strength will increase.
