Clark Technology: Here's a question that many of Clark customers ask: What's the difference between MIG and TIG welding?

A little confusion is perfectly normal. After all, both MIG and TIG welding procedures use electrical arcs to produce heat and join metallic objects. Also, both processes use an inert gas mixture to prevent the corrosion of welding electrodes.  But, there are some key differences between these two electrical arc welding processes which affect when you would want to use on or the other: Here are a few different types of welding processes that Clarks manufacturing team uses.

The two that are used the most often are:
• Metal Inert Gas (MIG) Welding. Also known as gas metal arc welding (GMAW), MIG welding uses a continuously-fed electrode wire that melts into the weld. This melted wire acts as a filler material in the weld—allowing two pieces of metal to be joined without having to heat them to the melting point.
• Tungsten Inert Gas (TIG) Welding. Also known as gas tungsten arc welding (GTAW), TIG welding has a non-consumable electrode that heats metal to the melting point so it can be fused directly. Requires strict control to prevent over-heating of metal.
