SOLIDIFICATION CRACKS IN WELDING 🔧 Solidification cracks are hot cracks that occur during weld metal solidification due to the presence of low melting point impurities. Visit weldfabworld.com 🔹 Crack Mechanism Low melting point elements such as Sulphur (S) and Phosphorus (P) segregate at the grain boundaries during solidification, reducing cohesion and leading to cracking. 🔹 Example Iron Sulphur → Iron Sulphide (FeS) Iron sulphide has a low melting point, which promotes solidification crackin
