The development technology and industry, steel one important materials, evidenced common use world manufacturing, maritime, building materials, piping, oil and gas. Therefore, important study and optimize welding process parameters improve joint quality and minimize defects. This study aims obtain various combinations MIG (Metal Inert Gas) process parameters steel welding variations current strength and coolant effect results microstructure and Vickers hardness tests. The research method involves welding variations current strength coolant, followed Vickers hardness (HV) testing and microstructure analysis. The results showed highest hardness value specimen 4 current strength 100A using water coolant, average hardness of 297.5 HV. Rapid cooling water and low welding currents produce welds tighter particles and minimal defects, microstructure dominated martensite, ferrite, and pearlite. On other hand, lowest hardness value specimen 9 current strength 120A using water cooling, produces average of 281.2 HV because cooling process slower and current high causing more welding defects.
