MIG Welding Wire
Filler metal for GMAW (gas metal arc welding) activities is provided by MIG (metal inert gas) wire. To keep impurities out of the weld pool, this solid wire, also known as welding wire or filler wire, requires external shielding gas. It comes on a coil or spool and is fed through a welding gun that is compatible with it. A weld is formed when an arc is formed between a wire and a workpiece, and the heat from the arc melts and fuses material from the workpiece and the wire.
