Air-cooled GTAW torches are primarily cooled by which of the following?
As the nozzle size decreases for GTAW, the shielding gas flow rate should be______.
Turbulence in the shielding gas may be caused by which of the following?
There are many different types of tungsten electrodes that can be used with GTAW. What is the best method of determining the type of tungsten being used?
When GTAW is done properly, the tungsten electrode is considered to be "non-consumable" because it does not melt or transfer to the weld.
If the welding current is set too high for a given diameter electrode, the electrode will melt causing what type of inclusions in the weld metal?
