Welding Hot Cracks🔥 Hot cracks (also called solidification or liquation cracking) are among the most dangerous welding defects. They form at high temperatures, near the solidus, when the weld is still partially molten and extremely brittle. 🔍Where do they occur? · Weld Metal → Solidification cracking (centerline of bead). · HAZ → Liquation cracking (partially melted zone). ⚠️ Why and when do they happen? · Lack of ductility at high temperature. · Impurities (S & P) segregating at grain boundar
