Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing fusion. It is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. Welding is commonly performed using an electric arc or a gas flame to melt the edges of the workpieces to be joined together. Pressure is then applied to force the molten metal to fuse.
Welding is a versatile and widely used process in the manufacturing, construction, and repair industries. It is used to create everything from small electronic components to large bridges and buildings. Welding is also used in art and sculpture.
