Flt Crack ((hot))s — Hot

The phrase refers to hot cracking in welding, specifically within the fusion zone of a weld. It describes a phenomenon where the liquid metal in a fillet weld cannot accommodate the shrinkage strain as it cools, leading to immediate fracture. Key Characteristics of Hot Cracking

| Crack Type | Appearance | Primary Cause | Progression Rate | | :--- | :--- | :--- | :--- | | | Starts as a 1-2mm hairline at the heel radius; propagates diagonally toward the tip. | Repeated overload bending (plastic deformation). | Rapid (Hours to days) | | Thermal Check Cracking | Network of shallow, star-shaped cracks on the blade surface. | Rapid heating/cooling cycles (e.g., moving molten metal or frozen goods). | Slow (Months) but leads to spalling. | | Root Weld Crack | Longitudinal crack along the back of the hook weld. | Shock loading (dropping a load onto the forks). | Sudden (Catastrophic) | flt cracks hot

This consistency keeps FLT in the "hot" rotation alongside groups like and TENOKE . The phrase refers to hot cracking in welding,

The FLT cracks have significant implications for the lifestyle and entertainment industry: | Repeated overload bending (plastic deformation)

: Ensuring the fillet has a slightly convex shape rather than a concave one adds more material to the center, helping it resist contraction forces. Hot tearing of Mg-Ca binary and Mg-Ca-Zn ternary alloys
