IIW IWT Practice Questions - IIW International Welding Technologist (IWT) Exam - IIW IWT Practice Questions - IIW International Welding Technologist (IWT) Exam

Question 1

In the gas metal arc welding (GMAW) spray transfer mode, how is metal transferred from the electrode to the weld pool?

As large droplets that short-circuit the arc at regular intervals As a fine stream of tiny droplets propelled axially across the arc without short-circuiting Only by gravity when welding in the flat position Through globular drops detaching mainly from arc-blow forces

Correct Answer:

As a fine stream of tiny droplets propelled axially across the arc without short-circuiting

Question 2

Which shielding gas is REQUIRED for gas tungsten arc welding (GTAW/TIG) of most metals to protect the tungsten electrode?

Pure carbon dioxide An oxidising argon-oxygen mixture An inert gas such as argon or helium Compressed air

Correct Answer:

An inert gas such as argon or helium

Question 3

A welding power source described as having a 'constant current' (drooping) static characteristic is most appropriate for which process?

Gas metal arc welding (GMAW) with spray transfer Manual metal arc welding (MMA/SMAW) Submerged arc welding with a single wire and high deposition Flux-cored arc welding on a wire feeder

Correct Answer:

Manual metal arc welding (MMA/SMAW)

Question 4

In submerged arc welding (SAW), what is the primary function of the granular flux?

To act as the filler metal that forms the weld bead To provide arc shielding, slag protection and metallurgical refinement while concealing the arc To cool the workpiece rapidly and increase the cooling rate To electrically insulate the contact tip from the wire

Correct Answer:

To provide arc shielding, slag protection and metallurgical refinement while concealing the arc

Question 5

Why is direct current electrode positive (DCEP / reverse polarity) generally preferred for manual metal arc welding with most coated electrodes?

It concentrates more heat in the electrode to increase deposition rate It produces a cleaning action and good penetration with deeper fusion into the workpiece It eliminates the need for any flux coating It allows welding without a return (earth) lead

Correct Answer:

It produces a cleaning action and good penetration with deeper fusion into the workpiece
