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.
