What is Cold Cracking and Hardness in P460NL1 Steel about?

The study evaluates the microstructural development, hardness, and notch toughness of P460NL1 steel weld joints at various preheating temperatures using FCAW and SAW processes. Results indicate that preheating reduces hardness in critical areas and improves toughness, while cold cracking was observed at room temperature. The research aims to inform welding procedures for industrial applications based on these findings.
