What phase should the copper tube joint be embraced to differentiate between solids and liquids?

The melting range is the phase during which a material transitions from solid to liquid. Understanding this range is crucial in processes like soldering and brazing, as it helps define the temperature limits within which the copper tube joint must be manipulated.

In the context of differentiating between solids and liquids, the melting range indicates the temperature at which the solid begins to change into a liquid. This range provides vital information for ensuring that the materials being joined reach a proper state for effective bonding. Proper temperature control ensures that the solder or filler material can flow adequately into the joint while avoiding overheating, which could damage the components involved.

Recognizing the melting range is essential for successful joint formation in soldering and brazing, as it ensures that the materials are in a workable state to form solid bonds upon solidification.
