Külmliide
Külmliide is an Estonian term that translates to "cold joint" or "cold weld." It refers to a type of defect that can occur in metal casting or welding processes. A külmliide happens when molten metal fails to properly fuse with an existing surface or another stream of molten metal due to insufficient temperature or flow. This results in a weak, incomplete bond where two pieces of metal meet, often appearing as a distinct line or a porous area.
In casting, külmliide can occur if the molten metal cools too much before it completely fills a
The presence of a külmliide can significantly weaken a component, making it prone to failure under stress
