Investigation of the Effects of Gas Metal Arc Welding Parameters on Tensile Strength

In this study, the effects of arc current and voltage on the tensile strength of S700MC steel welded using the Gas Metal ArcWelding GMAW method were examined.Parameters other than arc current and voltage were kept constant, and welding connections were produced according to a designed experimental plan.Tensile tests revealed that high arc voltage, which leads to a longer arc length, increased the weld seam width while decreasing penetration, thereby reducing tensile strength.Shorter arc lengths were found to produce more robust weld joints, with tensile strength values approximately 15 higher compared to those with longer arc lengths.
