This process is the workhorse of high-volume manufacturing, such as automotive assembly lines, due to its speed, ease of automation, and ability to weld thin materials effectively. The process accommodates solid wire or flux-cored wire, the latter being a tubular electrode filled with flux that creates its own shielding gas, combining the advantages of stick and MIG principles for even greater deposition rates.
Common Welding Process Types Overview
The welder manually controls the electrode, making MMA ideal for outdoor work, field repairs, and fabrication where complex setups are impractical, though it requires a steady hand to maintain arc length and consistent travel speed. The primary challenge for the welder is to concentrate this heat precisely where needed without excessively heating the surrounding area, which can weaken the metal or cause distortion.
This fundamental technique underpins modern manufacturing, construction, and repair across countless industries, from skyscrapers and ships to automobiles and medical devices. Welding is the high‑temperature process of joining metals by melting the base material and, often, a filler metal to create a permanent bond.
Common Welding Process Types Overview
"MIG" typically implies an inert gas shield, while "MAG" (Metal Active Gas) uses a mix of argon and active gases like CO2, which provides deeper penetration and higher welding speeds for carbon steel. Effective on a wide range of metals, including structural steel, stainless steel, and cast iron.
