Welding is the fabrication process that fuses like materials togeather by heating them to a suitable temperatures, this can be acomplished by brazing, soldering or welding. The filler metal has a melting point approximately the same or below that of the metals being joined togeather. Welding is done by melting like metals then add a filler material to the joint, once cooled forming a sturdy joint. Brazing and soldering is the melting of a filler material that is pulled into the gap between materials joining them togeather. The brazing filler has a melting point below the materials being joind togeather.
There are many different types of welds, techniques, designs, codes and procedures.
