MIG refers to metal inert gas. MIG welding is a semi-automatic consumable electrode process which is suitable for manual, mechanised and robotic welding.
A low voltage (12–45V), high current (60–500A) arc between the end of a consumable wire electrode and the workpiece provides the heat needed for the welding operation. The consumable wire electrode is continuously fed through the welding torch, where it melts, mixes with the molten base material and forms a weld pool. The weld pool and surrounding areas are protected from atmospheric contamination by a welding/shielding gas. This gas also stabilises the arc and assists metal transfer.
Air Products’ MIG/MAG weld process gases are designed to deliver optimum performance. All of these gases meet the requirements of ISO14175/AWS 5.32 - Welding consumables - Gases and gas mixtures for fusion welding and allied processes.
Air Products offer its best-in-class Maxx® gases range that offers users the optimum gas mixture whether you are welding carbon steel, stainless steel or aluminium.
There is a such a range of gases available — can I test them out and see what suits my process?
There is a best gas for every process and we carry a range of demonstration gases and our Maxx® gases range offers a solution for 98% of applications.
