"QUALITY IS MORE IMPORTANT THAN QUANTITY"

[Srinivas Engr]

Hi

MIG - Metal inert Gas Welding By with Inert gases Like Argon & Helium
MAG - Metal Active Gas Welding by with Active Gases like CO2 / with
oxygen.

Both above are called GMAW. MAG are mostly usable in construction with
CO2
I hope its clear...

Dear Asim ,

 

MIG (metal inert gas) welding and MAG (metal active gas) welding are two sub types of welding method classified as GMAS (gas metal arc welding). In both there processes a continuous metal wire surrounded by a shielding gas are fed through a welding gun. Of the two processes the first one to be developed was MIG process. This process was costly because of high cost of inert gas and therefor was not used that widely. It was mostly used for welding of non-ferrous metals. Subsequently the MIG process was developed which used semi active gas such as carbon dioxide (CO2). This allowed the process to be used for much wider applications.

I hope your doubt was cleared now .

Thank you .

Dear all,
I am Balamurugan . i like to share the answers with you.
MIG - Metal Inert Gas welding (Argon, Helium etc)

Sir

We use ArCO2 but our operators say eye irritation & more porosity occur in
jobs we use gas flow in pipe line not in cylinders anybody can clarify.

Thanks & regards

Dear Sir,
This is MAG as it is a mixture of inert and active gas .

we r using argon and corbon mixture gas for GMAW process,so i want to know whether it is MIG or MAG.

Mr. Asim Munir,

MIG & MAG both are divisions of GMAW (Gas Meal Arc Welding) process.

1. MIG- Metal Inert Gas uses,

   Argon(or) mixture of Argon(+) 20to25% Carbon DI-Oxide for welding of Carbon
   Steels.

   Argon(or) Argon(+) 2to3% Oxygen for welding non-ferrous metals like SS,AS,CU
   and all metals.

   Argon (or) Argon (+) Helium for AL and its alloys welding.

   It is non reactive and will not contribute further to any chemical & mechanical
   properties towards weld metal output.


2. MAG- Metal Active Gas uses,

   Carbon DI-Oxide for welding of Carbon Steels.
   No other metals can be welded other than CS with Carbon DI-Oxide.
   
   It is a reactive gas and will dis-integrate into C, CO and picks up additional
   Oxygen from Carbon Di-Oxide again due to continues supply of shielding gas. 

   Hence,a chain reaction happening at high arc temperatures.  

   It results in Carbon pick up to an extent of 0.1 to 0.20% or so in the base metal
   and a slight modification of chemical (addition of C) & mechanical properties
   (higher UTS values)  than the filler metal in the  weld metal output.
