Metallographic Investigation on Postweld Heat‐Treated0.21%C‐1020 Steel Plates Joined by SMAW Method

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
This paper presents analysis and comparison into mechanical behaviour and microstructural attributes of postweld heat‐treated AISI 1020 (0.21%‐C) plates joined by the shielded metal arc welding (SMAW) process. The purpose of this work is to heat the welded samples uniformly so that a possible formation of austenite can be obtained, and hence, residual ...
