TIG welding - the most difficult to master?

TIG welding

TIG welding is considered one of the more difficult types of welding to learn...harder to master than mig or stick welding-Supplier Of Welding Rotator. That is because both hands are needed to tig weld. One hand holds a tig torch with a tungsten electrode that provides the arc and heat...and the other hand feeds the rod.  TIG welding equipment is generally more expensive and more difficult to set up because there is often a remote amperage foot pedal included and it takes a cylinder of argon or argon mix shielding gas to work.

Tig welding is the most versatile type of welding of all-Supplier Of Welding Rotator. Virtually all conventional metals can be welded with the tig process. Carbon and low alloy steels, stainless steel, nickel alloys, aluminum, magnesium, titanium, cobalt, and copper alloys can all be welded using this type of welding.

Plasma arc welding

Plasma arc welding is similar to tig welding except that the tungsten electrode is recessed inside a nozzle and the heat is created by ionizing gasses flowing around the arc. Plasma arc welding is used where high precision is required and in situations where a recessed electrode is beneficial.  Plasma arc welding is used extensively in aerospace applications for dimensional restoration of air seals and jet engine blade repair where thicknesses are often below .015" and amperages used are often single digit.
