The Difference Between MIG Welding Techniques and ACI Welding Techniques

Gas tig welding is an arc welding

Gas tig welding is an arc welding method which uses a tungsten inert filler metal to create the weld in a metal. The weld region and electrode are both shielded from external contamination or oxidation by a inert shielding gas. The process produces a strong, heat-resistant weld that has high resistance to abrasion, weathering and rusting. This welding is used to weld aluminum, tin, copper and nickel alloys.

TIG welding is a two step process: The first step is electrode heating, and the second step is the cooling of the weld puddle. The TIG welder operates with a continuous feed supply of inert gas, which makes the welding process safer than other similar methods. In TIG welding, the workpiece surface is heated before welding begins by exposing it to an arc or direct current, which is supplied by a power source. The arc is directed to the workpiece surface and the workpiece is held in place by a work clamp or bolt.

The TIG welder has a variety of inert gas mixtures as electrodes

These various compositions provide different electrode characteristics, depending on the application. A few examples of the commonly used TIG welding electrodes are: Nickel-Argon, Germanium, Tantalum, Cobalt, Zinc and Gallotite. The inert gases are selected based on their chemical properties and the application’s requirements.

As the welding process is carried out, the welder’s job is to maintain the proper pressure and the correct temperature for effective electrode conductivity and thermal conductivity. The MIG welding and ACI welding processes use a tachometer to mechanically monitor the flow of gas through the wire. The MIG welding technique involves feeding a welding rod up into the welding chamber. The rod is supplied with inert gas to ensure appropriate electrode conductivity, while the ACI method produces electric arc energy by feeding alternating current through the filler.

MIG welding techniques are generally used for smaller jobs

In the MIG technique, a tachometer is used to mechanically monitor the electrode flow; however, this equipment is not available when using ACI because the power source is not an electrical one. The ACI technique makes use of a solenoid-based control variable to stop the arc from occurring. The tachometer uses two electrical controls to mechanically adjust the flow of gas through the workpiece.

MIG welding techniques are generally used for smaller jobs that require more controlled and accurate equipment. ACI welding techniques are generally used for larger jobs requiring more accurate and consistent equipment. MIG and ACI are both used in construction and manufacturing where there is a need to control and regulate the pressure, temperature and flow of gas to provide the best welds and products. This ensures that the finished product meets all requirements. MIG and ACI can be used to weld most metals including iron, stainless steel, aluminum, copper, brass and bronze.
