The process characterized by fusing two pieces of material using a heat process is welding. Welding involves melting the edges of the materials to be joined and allowing them to fuse together as they cool. This method is commonly used in metalworking and construction due to its ability to create strong, permanent joints.

In contrast, soldering and brazing also involve joining materials but with some distinctions. Soldering uses a filler metal with a lower melting point than that of the workpieces, generally below 450°C (about 840°F). In contrast, brazing utilizes a filler metal with a higher melting point than soldering but still lower than that of the base materials. Although all three processes involve joining materials, welding is unique in that it primarily fuses the base materials themselves, while soldering and brazing rely on filler materials.

Embossing, on the other hand, does not involve fusing or joining materials. It is a process used to create raised or depressed designs on a surface and is primarily associated with paper crafting or metal work for decorative effects, not structural joining.
