1. Welding electrode types

   • ceriated
   • Lanthanted
   • Zirconiated
   • Thoriated
   • pure tungsten

2. gases used

   • argon
   • helium
   • argon and helium mix

3. facts

   • this uses a form of filler wire to help solidify the weld pool and form the actual weld
   • tungsten is a non consumable
   • shielding gases are used they are used to protect the weld. these also prevent oxidation

4. Advantages of using tig

   • no flux is required
   • wider range of metals and alloys can be welded
   • no slag
   • no spatter
   • arc is more concentrated giving deeper penetration
   • more control
