Differences Between MIG Vs TIG WeldingĪs you can see from the quick description, there are substantial differences between the two ways. This allows welders to fine-tune the amount of heat they apply to the metal when welding.įor further details on the TIG welding procedure, please see my GTAW welding guide. In addition, tungsten oxide contaminates your weld.Ī foot pedal is frequently used to control the amperage while welding, albeit it is not shown in the diagram. When CO2 is present, tungsten oxide is created, and tungsten oxide prematurely wears down a tungsten electrode. Rather of the argon/CO2 mixture used in MIG welding, TIG welding shielding gas is usually 100 percent argon. The TIG filler rod’s composition and size will vary depending on the type of weld you’re doing, just like the consumable MIG wire electrode. With your second hand, manually feed a “rod” of filler material into the weld puddle as the non-consumable tungsten electrode forms an arc. MIG welding, on the other hand, is distinguished from TIG welding by the use of a non-consumable tungsten electrode and a separate consumable filler material. In the TIG welding technique, an arc is also used. Tungsten inert gas (TIG) welding is also known as gas tungsten arc welding (GTAW). ![]() The shielding gas, on the other hand, varies depending on what you’re welding and other variables.Īdditional information about MIG welding can be found in my post on the technique. This combination promotes weld penetration while reducing bead porosity. As a result, the wire feed speed (WFS), which must be adjusted to provide the right quantity of weld metal for the joint, is one of the most critical MIG welder settings.įurthermore, the shielding gas used is often a mixture of 75 percent argon and 25% CO2. ![]() The solid electrode wire is fed from the MIG welder to the torch, where it is consumed on various sized spools. The type of metal, its thickness, and the placement of the joints all have an impact on which procedure you use. In contrast, MIG welding uses a semi-automatic or automatic arc to weld.Ī continuous, consumable wire electrode is also utilized, as well as a shielding gas, both of which are provided to a welding gun via a lead (sometimes called a torch).īecause the wire electrode also serves as a weld filler material, the wire diameter and composition will vary. When detailing the MIG process, it’s easy to get carried away.
