MIG welding, or Metal Inert Gas welding, is often the preferred method for structural repair due to its versatility and speed. This welding technique utilizes a continuous wire feed that acts as both electrode and filler material, allowing for efficient and smooth operation. The shielding gas helps to protect the molten weld pool from contamination by atmospheric gases, resulting in cleaner welds.

MIG welding is particularly advantageous in structural repair scenarios because it can be used on a variety of metals, including steel and aluminum. It provides good penetration, which is critical for ensuring the integrity of the repair. Additionally, it is easier to learn and operate compared to some alternative methods, making it accessible for technicians and welders in various settings.

While TIG welding, arc welding, and oxy-acetylene welding each have their specific applications and advantages, they may not offer the same balance of speed, ease of use, and adaptability to different materials that MIG welding provides, especially in the context of structural repairs where efficiency and strength are paramount.
