PROC-301 — Welding Processes and
Equipment CWB Inspector Level 1(9
The heat of the welding arc is used to: - ANSWERS-locally melt the base material and filler
material to create fusion upon solidification.
The two main methods of arc shielding are: - ANSWERS-Flux shielding and gas shielding.
An example of solid state welding (SSW) is: - ANSWERS-Explosion welding (EXW)
In welding, the arc is intensely hot with temperatures exceeding: - ANSWERS-30,000 °C (54,000
°F)
Balled or rounded ends are often used for welding on materials that require a cleaning action to
remove a surface oxide layer (aluminum or magnesium). - ANSWERS-True
What is a weld called when no filler is added while using the gas tungsten arc welding process? -
ANSWERS-An autogenous weld.
The GTAW process was developed to weld more difficult materials, such as corrosion-resistant
alloys. - ANSWERS-True
When grinding a GTAW electrode, the grinding marks should be parallel to the length of the
electrode. If the electrode is ground with the marks going circumferentially around the
diameter, the arc will be: - ANSWERS-Unstable
, In GTAW, AC combines the advantages of both DCEN and DCEP, where DCEN provides increased
penetration and DCEP provides: - ANSWERS-the cleaning action.
Which of the following processes uses a non-consumable electrode? - ANSWERS-GTAW
What does the third number in an SMAW electrode classification represent? - ANSWERS-The
welding position.
What temperature should electrode holding ovens be held at? - ANSWERS-120 degrees Celcius.
Wet low-hydrogen electrodes should be: - ANSWERS-discarded.
The primary control on a SMAW power source is: - ANSWERS-Current.
Which of the following does the welder manipulate when using the SMAW processes? -
ANSWERS-The current setting, the speed of travel, the arc length, and the electrode angle.
What are examples of an F3 fast-freeze SMAW electrode? - ANSWERS-EXX10, EXX11.
Which of the following statements applies to the GMAW process? - ANSWERS-A continuously-
fed electrode is used.
What are the four modes of transfer used in gas metal arc welding? - ANSWERS-Short circuit,
globular, spray, and pulsed.
An advantage of GMAW pulse transfer is reduced heat input. - ANSWERS-True
