Tungsten inert gas welding (TIG), also known as gas tungsten arc welding (GTAW), is a method of welding best used for joining different kinds of metal, welding heat-sensitive metals and welding titanium. The process makes use of a non-consumable electrode made up of tungsten to produce a weld.
Capabilities and limitations of TIG welding
TIG welders make use of a tungsten electrode which is smaller in size compared to the traditional stick-welding rod. The small size enables more precise welds and the ability to weld on thin metals, as well as heat-sensitive ones.TIG welding is also used for applications that require precise and clean strokes (e.g. automotive work, sculpting).
Limitations of the method include increased cleaning and preparation time before welding. Cleaning is important since contaminations can weaken and blemish the weld. Compared to other welding techniques, TIG welding is the most time-consuming.
How to choose a TIG welder for your needs
These factors are guidelines that can be used to make an informed decision when buying a TIG welder. The most defining factor would still be one’s preference.
