Mechanical and microstructural characterization of dissimilar welded joints between S355J2 + N and S690QL steels using G69 and T46 filler wires
<jats:p> This study evaluates and compares the mechanical performance and microstructures of dissimilar welded joints made from S355J2 + N and S690QL steels, using G69 and T46 fillers. Tensile, Charpy V-notch (CVN) impact, and hardness tests were conducted, along with optical microscopy and scanning...
