Q:

What is the difference between MIG and TIG welding?

A:

Quick Answer

The difference between MIG and TIG welding is that the MIG welding technique feeds a continuous spool of wire into the melding puddle while TIG uses long welding rods to accomplish a similar task. The MIG welding process is done with metal inert gas. The TIG welding process is done with tungsten inert gas.

Full Answer

Both MIG and TIG welding techniques are widely used and require a certain amount of practice before they are mastered. Out of the two, MIG welding is easier to learn and perform. A MIG welder feeds a continuous spool of wire that melts after burning at a high temperature. Metals that work well with this technique include aluminum, steel and mild steel. MIG welding is very versatile and used on many different types of welding projects. MIG welding machines are recommended for less advanced projects.

TIG welding requires a bit more skill to master. TIG welding uses long metal rods of various sizes. Some common metals used with this method are aluminum, copper, stainless steel and iron. A rule of thumb is to use thin rods with thin metals and thick rods with thick metals. This form of welding is often used on projects requiring thin metal. TIG offers a lot of versatility when working on more intricate welding projects.

  • Q:

    What are some MIG welding tips?

    A:

    When MIG welding, always use a smaller diameter wire for thinner metals and larger wire for thicker metals. Thick metals also require a larger machine. Make sure that the electrode extends from the tip of the contact tube by at least 1/4 inch, and always use the appropriate shielding gas for the type of metal being welded.

  • Q:

    What is MIG welding?

    A:

    Metal inert gas welding is a welding process that uses a wire electrode that is fed through a welding gun and is melted off continuously in an electric arc. An inert shielding gas is produced by the welding gun to protect the arc from contamination.

  • Q:

    How does one set up a TIG welder?

    A:

    Setting up a TIG welder begins with connecting the welding machine and the torch, and then plugging the regulator hose in at the marked spots. Connect the grounding clamp into the grounded object, such as a work table. Set the welder properly, and then prepare the tungsten wire. Insert the tungsten wire into the torch, turn the machine on and start welding.
