TIG welding is a type of welding that uses non-consumable gas and tungsten electrode. This type of welding uses inert gases as a filter to prevent atmospheric pollution. Plasma and metal vapors are the real means of welding.
Plasma is formed by the constant current power supply that this welding method uses. TIG welding is a difficult skill to master. TIG welding requires exceptional hand and eye coordination. You will also need a high-quality sense and balance, as well as the ability to use both your hands simultaneously.
Anyone who has ever experienced Tig Welding knows that TIG welding is highly dependent on maintaining the shape and quality of the tungsten tip. Automatic TIG welding applications require significant data regarding the set-up of welds. Tungsten's life expectancy is increased by a rise from a low current starting point, then a rise to the operating current.
Expert TIG welders know their secrets to success in this critical industry. Because they are experts in TIG, they have a deep understanding of the industry. They know how to balance and solve problems, fix their mistakes, and create a flawless weld.
The torch is held by the TIG system. The operator begins the arc when the cup bends on the weld joint. The torch knob is then turned side to side, much like a ratchet turning a bolt. Once metal begins, the filler wire can be walked over or dipped.
