مقاله اصلی بررسی مشخصات استرس باقی مانده سطحی در جوش خوردگی فولاد ضد زنگ مارنزیتی با پراش اشعه ایکس

The development of residual stresses during fabrication is inevitable and often neglected with dire consequences during the service life of the fabricated components. In this work, the surface residual stress profile following the martensitic stainless steel (MSS) pipe welding was investigated with X-ray diffraction technique. The results revealed the presence of residual stresses equilibrated across the weldment zones. Tensile residual stress observed in weld metal was balanced by compressive residual stresses in the parent material on the opposing sides of weld metal.
