What are the key differences between MIG and TIG welding?

MIG (Metal Inert Gas) welding uses a continuously fed wire electrode and is faster, easier to learn, and suitable for thicker materials and high-production environments. TIG (Tungsten Inert Gas) welding uses a non-consumable tungsten electrode with separate filler rod, offering superior control, cleaner welds, and is preferred for thin materials, precision work, and aesthetic welds on stainless steel and aluminum.
