Abstract :
Shield metal arc welding ( SMAW ) is welding with a bow fiery electricity used as a source of heat to melt metal ( electrodes ) the study is done to know mechanical properties steel st 37 , where done welding using variations of current 90A , 100A , 120A with a kind of electrodes E7018 diameter 3,2 mm , the kampuh v for 70 .Based on the research done is obtained strong pull the lowest with the current 90A of 11,4 N/ mm2 .And strong trick on the highest the current 120A of 11,55 n / mm 2 , and strength the lowest charpy to the current 90a -0,9646 j / mm2 highest of -0,95975 j / mm2 to the current 120a .
