TIG Welding

Tungsten Inert Gas Welding,Tig Welding

Tungsten Inert Gas (TIG) welding uses the heat generated by an electric arc struck between a non-consumable tungsten electrode and the workpiece to fuse metal in the joint area and produce a molten weld pool. TIG welding produces temperatures up to 35,000 degrees Fahrenheit, yet this concentrated heat can be precisely controlled and directed. When filler metal is required, it can be added manually by feeding welding rod into the puddle, similar to oxyacetylene welding. In fact, oxyacetylene welders usually pick up TIG welding fairly easily.

TIG welding applications

TIG welding is a highly practical skill with various applications. TIG is the most versatile type of welding and can be used on steel, bronze, titanium, copper, aluminium, stainless steel, Chromoly, nickel alloys, magnesium, brass, and gold.

TIG is a useful process for welding

  • Bike frames
  • Pipe welding
  • Wagons
  • Lawnmowers
  • Airplanes
  • Automobiles
  • Medical and scientific equipment

Features of TIG Welding

  • A non-consumable tungsten rod is used in TIG welding
  • If required, Filler metal can be added manually.
  • Shielding gas helps in protecting the weld and tungsten
  • High quality and clean welds are achieved.
  • TIG welding allows welding of more metals than any other process.

TIG welding FAQ

Is TIG welding difficult?
Gas tungsten arc welding (GTAW), or TIG, is often specified to meet strict aesthetic, structural or code/standard requirements. The TIG process is complex, and it is undisputedly the most difficult process to learn.
What metals Cannot be TIG welded?
  1. Titanium and steel.
  2. Aluminum and copper.
  3. Aluminum and stainless steel.
  4. Aluminum and carbon steel.
What is the hardest metal to weld?
Originally Answered: What kind of metal is the most difficult to weld? Titanium is probably the most difficult. It has to be surrounded by an inert gas like argon.
Do you TIG with AC or DC?
DC is used for TIG welding Mild Steel/Stainless material and AC would be used for welding Aluminium. The TIG welding process has three options of welding current based upon the type of connection. Each method of connection has both advantages and disadvantages.
