Abstract

Addition of metal powder ratio which is one of factors increasing welding efficiency is affected by welding parameters in submerged arc welding with additional metal powders. A determination of the additional metal powder proportion suitable with welding parameters plays an important role in achieving high quality and productivity. This paper investigates effect of addition metal powder ratio and welding technology parameters on tensile strength and impact toughness that evaluate the weld quality. Results show that the addition metal powder ratio and welding technology parameters significantly affect tensile strength as well as impact toughness. Research result provides basis information for the application of this technology in the manufacturing and fabrication of welded structures.
