What process describes the melting together of filter material and base material resulting in coalescence?

The process that involves the melting together of filter material and base material to achieve coalescence is referred to as fusion. This term describes the way materials are joined at a molecular level by heating them to their melting points so that they blend together without the addition of another material.

In the context of manufacturing and engineering, fusion is crucial because it allows different materials to bond seamlessly, ensuring strong and durable connections. This process is distinct from welding, which often involves the use of filler materials, or soldering, which primarily applies to metal all joinage at lower temperatures and typically uses a filler metal to create the bond.

Understanding fusion is important because it highlights the physical and chemical processes involved in effectively combining materials in various applications.
