Semiautomatic Welding

MIG welding - Arc welding automatically fed wire electrode (wire) in the inert gas.

Standard notation semiautomatic welding
MIG - Metal Inert Gas (Welding) - metal welding in an inert gas MAG - Metal Active Gas (Welding) - metal welding in active gas GMAW - Gas Metal Arc Welding - metal arc welding in a gas medium

Semiautomatic welding in carbon dioxide
Semiautomatic welding in carbon dioxide (CO 2 ) is the main and most common fusion welding technology in enterprises of machine-building industry. It is economical, provides a sufficiently high quality welds, especially for welding carbon steels, it is possible in different spatial positions, requires a more low-skilled welder than manual arc welding.

Semi-automatic welding process scheme

Shielding gas, leaving the nozzle, displacing the air from the weld zone. Welding wire is fed down the rollers, which rotate motor feeder. Welding power supply to the wire via a sliding contact.

Given that the protective gas is active and can interact with the molten metal, semi-automatic welding in carbon dioxide has a number of features.
