MIG/MAG

Part 5 1988, Primary method for the determination of diffusible hydrogen in MIG, MAG, TIG or continuous wire flux cored weld metal.

Aluminum bronzes can be easily welded with the manual welding procedures, MIG/MAG and WIG (alternating current). Both connection welding as well as large build-up welding can easily be implemented with SG-CuA18Ni2 after DIN 1733 filler material. 

It comprises an outer sheath of steel (usually mild steel) which contains flux and/or metallic ingredients. The sheath may be a fine hollow tube or a strip wrapped round the core. Cored wires may be used for MAG, MIG or submerged-arc welding. 

The term was originally used (and sometimes still is used) for both MIG and MAG welding (q.v.). 

Tungsten Inert Gas (TIG) In this case, an unfusible tungsten electrode is used together with a separated filler stick the protection of the melted material is obtained through an inert gas shield (Fig. 4). Such processes are characterized by either an inert gas (MIG - metal inert gas) or an active one (MAG - metal active gas), on the basis of the type of used gas. With respect to other fusion welding operation, TIG is characterized by a focused heat flux and a limited heat-affected zone (Rodrigues and Martins 2005). 

MIG and MAG are the most common welding methods. The high levels of productivity offered by these methods and the fact that they are simple to automate have contributed to their popularity. The methods together are often referred to as gas metal arc welding (GMAW). 

In MIG (metal inert gas) and MAG (metal active gas) systems the welding electrode is an uncoated wire, fed from a gun held by the operator. Oxidation of the weld is prevented by shielding it with a gas dispensed via the gun. The...
