WLD 107: TIG Final
The GTAW process uses a nonconsumable tungsten electrode to supply welding
current to the workpiece. - Answer-True
Filler metal is necessary on all welds made with the GTAW process. - Answer-False
DCEP allows deeper penetration than DCEN. - Answer-False
A remote current control allows the welder to adjust current while welding. - Answer-
True
Postflow is the flow of shielding gas after the arc is extinguished. - Answer-True
The chemical symbol for tungsten is W. - Answer-True
When welding with DCEN, the electrode is positive and the work is negative. - Answer-
True
Alloyed tungsten electrodes last longer and have a higher current capacity than pure
tungsten electrodes. - Answer-True
Filler metals for GTAW use the same classification system as filler metals used for
GMAW. - Answer-True
The addition of helium to argon shielding gas improves penetration. - Answer-True
Filler metals for oxyacetylene can be used for GTAW as long as they are copper-
coated. - Answer-True
Argon is the most commonly used as a shielding gas in the GTAW process. - Answer-
True
The amount of electrode stickout is determined by the type of weld joint. - Answer-True
The filler metal used should have the same composition as the base metal. - Answer-
True
Shielding gas is not required after the arc is extinguished. - Answer-False
A flowmeter regulates the amount of shielding gas flowing to the torch. - Answer-True
A gas nozzle directs the shielding gas from the torch to the weld area. - Answer-True
Helium has a higher ionization potential than argon. - Answer-True
