Mohammed Asif M et al studied the impact of heat input on tensile strength‚ toughness‚ micro hardness‚ micro structure and corrosion behavior of duplex stainless steel joints. Four parameters were varied by keeping speed as constant. The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing
