Welding is a fabrication process that joins materials usually metals or thermoplastics by using high heat to melt the parts together and allowing them to cool causing fusion.Welding is distinct from lower temperature metal joining techniques such as brazing and soldering which do not melt the base metal. In addition to melting the base metal a filler material is typically added to the
