What Is MIG & TIG Welding?
The difference between MIG & TIG welding is that MIG uses continuous feeding wire and TIG uses welding rods that are slowly fed into the welding place.
In this style of welding, a thin wire acts as the electrode fed from a spool that is mounted on a gun or within the machine, through a flexible tube and comes out of the nozzle of the welding torch. The wire is fed continuously when the trigger on the torch is pressed.
An electric arc forms between this wire electrode and the workpiece and heats both metals above their melting point, these metals mix and solidify to join workpieces into a single piece.
MIG welding uses filler for the joint, because the wire electrode melts as its being used. These types of electrodes are called consumable electrodes.
Advantages of MIG welding
Disadvantages if MIG welding
It is a welding process in which heat is produced by an electric arc ignited between a base metal (workpiece) and the non-consumable tungsten electrode.
TIG welding uses a tungsten electrode because tungsten has a high melting point. When the TIG weld electrode gets hot but does not melt, it is a non-consumable electrode. The non-consumable electrode does not mean that it will last forever, it just means that it doesn't melt and become part of the weld.
