metal inert gas (MIG) welding
Mig
Flux core is a type of MIG welding.... please kind of know what your talking about before you ask a question.... Gas assisted solid mig wire welding is neater and cleaner. There are two types of flux core mig welding that you are talking about. 1. Gasless flux core mig wire 2. Shielded flux cored welding wire, uses a shielding gas as well. Most likely you are talking about the gasless mig wire. look here for more info: www.learn-how-to-weld.com/gasless-mig-wire.html
When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
metal inert gas (MIG) welding
DCEP for standard Mig. DCEN for Flux Core
MIG stands for metal inert gas. It is a non-standard term for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) according to the American Welding Society (AWS). It is simply Metal Inert Gas.
MIG welding with flux core wire offers advantages such as higher welding speed, better penetration, and increased portability compared to other welding methods.
A tubular or wire cored electrode is used for both MIG and MAG welding. These can be purchased online at places like AGA.com.
Gas Metal Arc Welding Most folks call it MIG
Wire feed speed in MIG welding is calculated by multiplying the welding current by the wire feed rate. This formula helps determine the speed at which the welding wire is fed into the weld pool during the welding process.
It depends on what you are welding. If you are doing welding on mild steel go with MIG welding; if it is aluminum or stainless steel then use TIG welding. TIG welding gives a nice looking finish. If you just want to get a decent look, then MIG is preferable and easy.
