Welding common material joining process used various industries, such automotive, construction, and shipping. some applications, combination two different metals (dissimilar metals), such carbon steel and stainless steel, required optimize strength, corrosion resistance, and cost efficiency. Carbon steel known strong and economical, while stainless steel resistant corrosion. This study uses Dissimilar Metal Welding (DMW) welding method stainless steel electrodes. After welding, specimens were cut using CNC machine and tested through Tensile and macrostructure tests. Tensile test results showed highest stress 369.342 Kgf/mm² specimen current 90A and water cooling, while lowest stress 116.036 Kgf/mm² current 70A air cooling. The highest strain value 0.039 occurred 90A, lowest stress value of 0.017 80A and highest elastic modulus 11,610 Kgf/mm² 90A, lowest 6,107 Kgf/mm2 70A. Macro testing showed best specimen 90A parameters because free defects, while worst specimen 70A parameters defects such arc strike, underfill, porosity, and slag inclusion due current being too low.
