Nissan Armada 2025-2026 Service and Repair Manual: Principles of MAG Welding
The welding electrode consists of a wire wound on a reel. This welding wire is fed by an electronically controlled motor.
The welding zone is shielded from the atmosphere by injecting a shielding gas. This prevents oxidation and nitriding so that greater weld strength and a good weld bead can be obtained. The shielding gas is argon, CO2, or a mixture of both.
The following figure shows the welding procedure.
Mag Welding
MAG welding uses the heat of an electric arc to join two pieces of metal by fusing both the metal and the electrode. For auto repair MAG (Metal Active Gas) are the types of arc welding most often used ...
