MIG Welding Basics

MIG welding is an arc welding process which joins metals by heating them with an arc. The arc is between a continuously fed filler metal (consumable) electrode and the workpiece. Externally supplied gas or gas mixtures provide shielding. Common MIG welding is also referred to as short circuit transfer. Metal is deposited only when the wire actually touches the work. No metal is transferred across the arc. Another method of MIG welding, spray transfer moves a stream of tiny molten droplets across the arc from the electrode to the weld puddle.

It is simple to choose the equipment, wire electrode, shielding gas and welding conditions capable of producing high-quality welds at a low cost.  Select from HTP America’s quality MIG welders to find an optimal solution for you.

Advantages of MIG Welders

The MIG welding process provides many advantages in manual and automatic metal joining for both low and high production applications. Its combined advantages when compared to covered (stick) electrode, submerged arc, and tig are:

  • Easiest welding process to learn

  • Welding can be done in all positions

  • High rate of filler metal deposition

  • Narrow weld bead

  • Creates clean, precise welds resulting in high weld quality

  • High welding speeds and less distortion of the workpiece

  • Gaps filled or bridged easily, making certain kinds of repair welding more efficient

  • No stub loss as with covered electrode

  • Cleaner - no slag to remove from weld

A further advantage is that the same equipment used for MIG welding also performs flux cored welding. Rather than running a solid wire coupled with a shielding gas, flux cored welding uses self-shielded wire with flux inside.
