In the present study, effect of Ni alloying element on the characteristics of deposited weld metal of E7018-G electrode was evaluated. Therefore, electrodes contained different amounts of Ni (0-1.7wt.%) were designed, manufactured and welded via SMAW process. Microstructural studies revealed dichotomy effect of Ni on the deposited weld metal microstructure, i.e. increasing the Ni content up to ...

ASTM A36 is the most used type of mild steel especially in construction and manufacturing industry. Welding process regularly employed to fix crack that usually occurs low carbon after a long time use In this study, effects heat treatment on mechanical properties [ASTM A36] lap welded joint were investigated. Seven pieces 60 mm × 300 bar for research. Five samples treated an electric muffle fur...
