REDUCTION OF RESIDUAL STRESSES IN WELDED JOINTS USING MECHANICAL VIBRATIONS

In this study, Metal Arc Welding of rolled steel (JIS G3101 SS400) specimens were studied under computational conditions. The finite element methodology of residual stresses in butt welding of bi-linear plates is conducted using ANSYS software. The study includes a finite element structure for heat (thermal) and structural (mechanical) welding simulation. Additionally, it also comprises of a poignant heat foundation, material dumps, heat dependant material chattels, metal agility and flexibility, transient heat shift and mechanical investigation. The welding replication was measured as a sequentially coupled thermo-mechanical scrutiny and the element birth and death technique was engaged for the investigation of filler metal authentication. The residual stress dispersion and enormity in the axial course was obtained. A good agreement between the theoretical and computed results was attained.
