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.
