TIG Welding

TIG is an acronym for Tungsten Inert Gas

• True

• False

When ending a TIG weld it is important to....

• Remove the torch immediately

• Remain still and allow the gas to flow over the cooling puddle.

TIG welding uses a tungsten electrode to conduct electricity to the puddle.

• True

• False

TIG welding was traditionally performed using helium as a sheilding gas and was therefore known as ____________.

• Heliarc

• GMAW

• SMAW

• None of these

Which of these shielding gasses are used for GTAW?

• Argon and Helium
• Argon and oxygen
• helium and Co2
• Co2 and nitrogen

How far from the work should the tip of the electrode be held after the welding arc is stabilized?

• Less than 1/16" 
• 1/16" - 1/8"
• 1/8" - 3/16"
• distance depends on the material thickness

An inert gas is used to keep the atmosphere away from the welding area

• True
• Flase

Grinding marks should run around the diameter of the electrode

• True
• false 

The GTAW process is much faster than SMAW, FCAW, OR GMAW

• True
• FALSE

A contaminated electrode will cause an unstable arc

• True
• false
