| description | The aim of this study is to investigate the influence of different heat inputs on mechanical properties
and microstructure of dissimilar electrical arc welded austenitic stainless steel AISI 304 and lowcarbon steel (CS) joints. The mechanical properties of welded austenitic stainless steel type AISI 304
and low-CS are studied. Five different heat inputs 0.5, 0.9, 1.41, 2, and 2.5 KJ/min were applied to
investigate the microstructure of the welded zone and mechanical properties. The results showed that
the efficiency of the joints and tensile strength increased with increasing heat inputs, while excess
heat input reduces the efficiency. Furthermore, changes in microstructure with excess heat input cause
failure at the heat-affected zone. |
