TIG welding was first invented in America ( USA ) in 1936, know as Argon arc welding. TIG allows top-quality welded joints to be produced with inert gas supports clean welding result. This welding method is and all-purpose welding procedure with regard to material used, wall thickness and welding positions.Continue reading “TIG Basic Welding Knowledge”
As defines in ISO 857-1, MIG welding is a gas-shielded metal arc welding, which is the wire is melted and shielded by the gas. The ISO standard defines that the MIG welding use a wire where by gas from an external source surrounds the arc and the weld pool to protect them from the atmosphere.Continue reading “MIG Basic Welding Knowledge”
MMA Welding is a welding procedure that uses a metal arc that plays an important role in the welding process. According to ISO 857-1 ( 1998 Edition ) this metal arc welding process uses electrodes without gas shield.
In Germany, this method is known as :
- E-Hand Schweissen
This type of welding machine is a flux based process that suitable for outdoor needs. Because the wind doesn’t affect the welding process. And this machine is also very suitable for welding needs on thick metal.
But the disadvantages of this welding machine, it can contaminate the metal because of the welding process itself. The metal that you weld will look dirty, so it’s not suitable for welding metal with clean needs, such as on production equipment, framing, automotive tools, etc.
If you’re doing agricultural needs, pipes and something like that, that do not prioritize the cleanliness of the welds, then this welding machine will help you perfectly.Continue reading “MMA Basic Welding Knowledge”
