“…Heat input is critical in welding operations as it directly affects the weld, heat‐affected zone (HAZ), and grain size. [ 11,12 ] Ramachandran et al [ 13 ] observed that as heat input rises, the microstructure of acicular ferrite (AF) and bainitic ferrite in the coarse‐grained HAZ of fusion‐welded HSLA steel transformed into a combination structure of polygonl ferrite, granular bainite (GB), and martensite‐austenite (M‐A) constituents. The former exhibits greater resilience, while the latter is more brittle.…”

The self‐developed Q960 high‐strength steel solid wire with different heat input is welded by MIG welding to solve the problem of insufficient low‐temperature toughness of Q960 steel weld. The effect of heat input on the microstructure and mechanical properties of butt welding deposited metal is studied in depth. The results show that the microstructure of deposited metal is composed of granular bainite (GB), degenerate upper bainite (DUB), martensite (M), and acicular ferrite (AF). DUB and M play key roles as strengthening phases, whereas GB and AF serve as primary toughening phases. Elevated heat input leads to a progressively rougher microstructure in the deposited metal. AF and DUB increase first and then decrease, GB increases and M decreases slightly. The inclusions conducive to AF nucleation are mainly composed of oxides of Mn, Si, Ti, and Mn sulfide with sizes between 100 and 500 nm. At a 14 kJ cm−1 heat input, the complex phase microstructure effectively refines the grain, and the high‐angle grain boundaries and ferrite interlocking structure optimize the strength and toughness balance of the deposited metals. The tensile strength measures 958 MPa, with the highest elongation at 19% and an average impact toughness of 50 J at −40 °C.

Enhancing corrosion resistance in stainless-ssteel alloys is a paramount objective in the petroleum industry. This study investigated the effects of the previous cold working and welding processes on the mechanical properties and corrosion rates of 204 Cu stainless steel in different aggressive environments (crude oil, freshwater, and seawater). The experimental sets were supported by microstructure analysis. The mean weight loss method was employed to determine the corrosion rates, which were optimized using the Taguchi method. The ferrite and austenite phase bands, as well as the deformed portions of austenite, are pushed to flatten out during cold working, which increases the material’s hardness. Cold-worked steels were welded, creating an annealed area around the HAZ in addition to the usual weld zones, which demonstrated partial microstructure recovery and hardness reduction. HAZ showed signs of iron overload and chromium nitride precipitation. Cold-worked specimens only showed reduced corrosion resistance to 30% of the initial rate and reduced thickness. Moreover, the Taguchi optimization technique indicated that the corrosion environment has the most effect on the corrosion rate compared to the cold work ratio for welded and non-welded stainless-steel specimens.
