TIG and MIG


TIG and MIG

The core difference between TIG welding and MIG welding lies in whether the electrodes melt and the welding efficiency. TIG is suitable for precision, high-quality welding, while MIG is suitable for high-efficiency mass production. According to Baidu Encyclopedia, TIG uses a non-melting tungsten electrode, while MIG uses a molten welding wire as the electrode.

Electrode Type: TIG uses a non-fusible tungsten electrode, which only generates an arc without filling metal; MIG uses a fusible welding wire, which both generates an arc and serves as filler material.

Shielding Gas: TIG typically uses a pure inert gas (such as argon) for purer protection; MIG commonly uses inert gases or mixed gases (such as argon + carbon dioxide) for wider applicability.
