TIG welding uses a tungsten electrode, inert gas, and ceramic cup to weld metal together. It offers versatility, amperage utilization, and control. The low amperage torch allows for welding thin pieces of metal and complex designs without leaving noticeable weld marks. TIG welding is clean and leaves no slag. The foot pedal mechanism allows for precise control of heat and amperage.
Tungsten inert gas (TIG) welding, sometimes called gas tungsten arc welding (GTAW), is a popular welding method in which a tungsten electrode, an inert gas, and a ceramic cup are used to weld metal together. TIG welding offers advantages in versatility and amperage utilization because it uses less energy than other welding methods. A clean weld is also achieved by making a low profile weld bead and there is no slag left after the weld is finished. The biggest advantage of TIG welding is control, both in terms of the electrode itself and the current.
TIG welding uses less amperage than other welding methods, which might seem like a disadvantage at first, but it really helps the TIG welder. When a torch uses a high amount of amperage, it’s great for large, thick bars of metal, but not so good for thin pieces of metal. With a low amperage torch, the TIG welder is capable of working on thin pieces of metal and other metals that cannot handle high amperages.
The lower amperage and a foot pedal mechanism that allows the welder to change the amperage make TIG welding more versatile than other welding methods. A welder can go from working on thin pieces of metal to working on thick ones, and can weld complex designs together without leaving noticeable weld marks. The TIG welder is small, almost like a pen, which allows welders to use it for almost any purpose. The inert gas used in the welding machine allows you to work on different metals. Argon is best for steel and titanium, helium is best for stainless steel and copper, and a combination of argon and helium is best for aluminum and alloys that include aluminum.
Some welding methods leave slag when finished, making the finished product look sloppy. This also wastes time, as the welder has to clean off the slag to make a presentable product or weld job. TIG welding is very clean and leaves no slag, so the welder can concentrate on welding instead of cleaning the metal.
The most cited benefit of a TIG welder is its control. Heat and amperage are precisely controlled and changed using a foot pedal mechanism. The soldering mechanism itself is very thin and pen-like, so while dexterity is required, the soldering iron has superior soldering control. This helps produce high quality weld work, especially when there are complex curves or designs in the base metal.
