Arc Current and Arc Voltage of Inert-Gas Welding Parameters, Research The Effect on Tensile Test

In this work, various welding connections was obtained while pegging parameters from the inert-gas welding not included as welding current and welding voltage. Project main purpose is, to see the effect of arc voltage and the arc current tensile loading on the connections that manual inert-gas welding what especially using in manifacturing sector in industry. For the connections S700MC material choosen as main material that quiet using for mobile crane manifacturing. After examined the results obtained as welding seam geometry and dilution, to estabilish the tensile loading, tensile loading samples taken off from the connections and tested. Remarkable results after tension test is seemed especially long arc lenght consequent of high voltage on the connections obtained high welding tension. Because of the long arc lenght dilution decreased and welding seam wideness increased . Additonally rapid cooling consist and internal stress increased obtained of the wideness seam geometry. As a natural consequence of these reasons, tensile loading that obtained with long arc lenght values %15 less then the small and medium arc lengts.
