1. In Oklahoma welding practice, which organization is responsible for
administering the state’s Welder Licensing Program, including
licensing welders, weld inspectors, and weld test facilities?
A. Oklahoma State Department of Education
B. Oklahoma Corporation Commission
C. Oklahoma Department of Labor
D. Oklahoma Construction Industries Board
Rationale: The Oklahoma Department of Labor administers the Welder
Licensing Program and is responsible for licensing welders, weld
inspectors, and weld test facilities under the state welding
requirements.
2. Which welding process uses a continuously fed consumable wire
electrode and an externally supplied shielding gas?
,A. SMAW
B. GMAW
C. GTAW
D. OFGW
Rationale: Gas Metal Arc Welding, or GMAW, uses a continuously fed
consumable electrode wire while shielding gas protects the molten weld
pool from atmospheric contamination.
3. A welder is preparing to perform Shielded Metal Arc Welding on
carbon steel. Which item provides both the electrical connection to
the electrode and the means of controlling the welding arc?
A. Gas regulator
B. Flowmeter
C. Electrode holder
D. Collet body
Rationale: The electrode holder grips the SMAW electrode and conducts
welding current from the power source to the electrode, allowing the
welder to establish and manipulate the arc.
4. What is the primary purpose of shielding gas in an arc-welding
process such as GMAW or GTAW?
A. To increase the melting point of the base metal
B. To mechanically strengthen the electrode
,C. To protect the molten weld pool from atmospheric contamination
D. To eliminate the need for proper joint preparation
Rationale: Shielding gas displaces atmospheric oxygen, nitrogen, and
other contaminants around the arc and molten metal, reducing
porosity, oxidation, and other weld defects.
5. Which welding process uses a nonconsumable tungsten electrode
to establish the arc?
A. SMAW
B. GMAW
C. FCAW
D. GTAW
Rationale: Gas Tungsten Arc Welding uses a nonconsumable tungsten
electrode, with shielding gas normally supplied through the torch to
protect the weld area.
6. In GTAW, why is the tungsten electrode generally kept from
contacting the molten weld pool during normal welding?
A. Contact causes the shielding gas to become flammable
B. Contact permanently magnetizes the workpiece
C. Contact can contaminate the tungsten and weld pool
D. Contact automatically reverses polarity
, Rationale: Touching the tungsten to the molten pool can transfer
tungsten into the weld and contaminate the electrode, requiring proper
cleaning or preparation before continuing.
7. Which process is commonly called “stick welding”?
A. GMAW
B. GTAW
C. SMAW
D. FCAW
Rationale: Shielded Metal Arc Welding is commonly known as stick
welding because it uses individual flux-coated electrodes that resemble
sticks.
8. What is the primary function of the flux coating on a conventional
SMAW electrode?
A. To eliminate the electrical arc
B. To prevent the electrode from melting
C. To provide shielding and form slag over the weld
D. To cool the base metal immediately
Rationale: SMAW electrode flux produces shielding gases and a
protective slag covering that helps protect the molten metal from
atmospheric contamination and influences weld characteristics.
9. A welder observes excessive porosity in a GMAW weld. Which
condition should be investigated first?
