The Differences Between Welding, Brazing and Soldering
Welding is a fabrication process that joins two or more parts by means of high heat, pressure or both. It melts the parts together and allows them to cool, resulting in fusion. Welding is typically used on metals and thermoplastics, but can be used on wood. Filler materials, which are extra pieces of metal, are often used to seal any gaps.
