A few broad areas for your consideration-
ELECTRICAL safety- when using any electrical equipment
THERMAL safety- when working with hot items
EYE and FACE safety- working with things that spatter. or produce ultraviolet light that can burn your eyes
RESPIRATORY safety- breathing fumes from welding is very unhealthy
FIRE safety- you can set things on fire
MATERAIL HANDLING safety- cuts and strains/sprain when moving heavy or sharp items
Mig
One type of welding is tube welding. Another type if mig welding.
CO2 and O2 can not be used in the same time for shielding gas in MIG welding, it would create too much oxidation of the molten metal.
See preceding question re: Mig welding.
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
metal inert gas (MIG) welding
Mig
One type of welding is tube welding. Another type if mig welding.
When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
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
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.
Gas Metal Arc Welding Most folks call it MIG
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, arc, mig and tig.
