Metal Inert Gas (MIG) welding is a popular welding process that uses a continuous wire feed as an electrode. This method involves feeding a spool of wire through a welding gun, which melts the wire to create a strong bond between metal pieces. An inert gas, typically argon or helium, shields the weld area from contaminants in the air, ensuring a clean and strong weld. MIG welding is known for its speed and versatility, making it suitable for various materials, including steel, aluminum, and stainless steel. It is commonly used in industries such as automotive, construction, and manufacturing due to its efficiency and ease of use.
