Gas Metal Arc Welding is to a greater extent than oft than non known as MIG (Metal Inert Gas) welding. Metal Inert Gas (MIG) welding is a normally used high deposition charge per unit of measurement welding process. Wire is continuously supplied from a spool. MIG welding is known to equally a semiautomatic welding process.
Principle of Operation
In the outset method electrical flow is passing as well as shielding gas is switched on to flow. Now the electrode is scratched against the project similar normal practise for hitting the arc.
In the second method, electrode touches the job, retracted as well as thence moved frontward to acquit out the welding; before hitting the arc, shielding gas, H2O as well as electrical flow is switched on. About fifteen mm length of the electrode is out of the torch earlier hitting the arc. During welding, torch remains near 10-12 mm the project as well as length should hold upwards betwixt 1.5 to four mm. Arc length is maintained constant yesteryear using t self-adjusted arc, as well as self-controlled arc inwards semi-automatic (manually operated) as well as automatic welding sets respectively.
