This study aims to determine the effect of variations in electric current and electrode movement pattern on the tensile test of St 37 steel in SMAW welding. In this study, the electric currents used were 80 A and 100 A with a zigzag and circular pattern. There were four specimens in this study, specimen I with a current of 80 A in a zigzag pattern, specimen II with a current of 80 A in a circul…
