Liquidus temperature
The liquidus temperature is the point where an alloy becomes fully liquid and no solid phase remains. It tells you the temperature where all crystal structure disappears.
Physical-Chemical Mode of Action
The liquidus temperature is the limit at which the alloy becomes fully liquid. This point corresponds to complete melting of all crystal structure and the development of a homogeneous liquid.
Metallurgical Relevance & Welding Risks
The liquidus temperature is crucial for selecting the welding process and shielding gases. If temperatures are too low, the material may not liquefy, leading to lack of fill or incomplete fusion. If too high, it can cause over-melting or rapid cooling, risking structural integrity.
Workshop Practice & Instructions
Determine the liquidus temperature of the alloy you're using and make sure it's maintained during welding. Use suitable shielding gases and control temperature precisely. If you have questions about the exact temperature, contact the material supplier or metallurgist.
