This study aims to determine the effect of variations in electric and the type of seam on SMAW welding on the strenght of the st 37 joint bending test. The currents used are 90 A, 110 A, and 130 A using V dan X seams the bending testing is curried out. Specimen 1 with an electric current of 90 A seam V, Specimen 2 with an electric current of 110 A seam V, Specimen 3 with an electric current of …
