1. What does the "D1.1" designation represent in AWS codes?
A. A type of filler metal
B. AWS Structural Welding Code – Steel
C. A welding process
D. A welder qualification test level
Rationale: D1.1 is the AWS code governing welding of structural steel, serving
as the primary code for structural steel welding in buildings and bridges.
2. Which welding process uses a consumable electrode with externally
supplied shielding gas?
A. SMAW
B. GTAW
C. GMAW
D. FCAW-S
Rationale: Gas Metal Arc Welding (GMAW) uses a continuously fed
consumable wire electrode and shielding gas supplied externally. The
electrode provides both the filler metal and the electrical path for the arc.
,3. What does SMAW stand for?
A. Shielded Metal Arc Welding
B. Structural Metal Arc Welding
C. Standard Mechanical Arc Welding
D. Shielded Machine Arc Welding
Rationale: SMAW is the formal designation for shielded metal arc welding,
commonly known as stick welding. It is widely used for structural steel
because of its portability, versatility, and suitability for field conditions.
4. Which electrode classification is commonly used for SMAW of structural
steel and provides low-hydrogen characteristics?
A. E6010
B. E7018
C. E7024
D. E6013
Rationale: E7018 is a low-hydrogen electrode that provides high strength and
low hydrogen characteristics, reducing the risk of hydrogen-induced cracking.
The "8" suffix indicates low-hydrogen coating with iron powder.
5. What is preheat primarily used for in structural steel welding?
A. To increase welding speed regardless of material thickness
B. To eliminate the need for proper joint preparation
C. To control cooling rate and reduce the likelihood of hydrogen-related
cracking
D. To guarantee that all weld discontinuities will disappear
Rationale: Preheat raises the base metal temperature before welding and
reduces the cooling rate. Slower cooling reduces the formation of excessively
,hard microstructures and allows more time for diffusible hydrogen to escape,
reducing cracking risk.
6. What does WPS stand for?
A. Welding Procedure Specification
B. Work Process Sheet
C. Welding Protection Standard
D. Work Procedure System
Rationale: A Welding Procedure Specification (WPS) is a written document
that provides direction to the welder for making production welds in
accordance with code requirements. It outlines the approved welding
procedure, including materials, processes, and parameters.
7. What is a PQR?
A. Production Quality Record
B. Procedure Qualification Record
C. Process Quality Review
D. Pressure Qualification Report
Rationale: A Procedure Qualification Record (PQR) documents the actual test
results and variables used during qualification welding. It validates that the
WPS can produce a weld meeting required mechanical properties.
8. What is the term for the maximum temperature between welding passes?
A. Preheat temperature
B. Interpass temperature
C. Post-heat temperature
D. Ambient temperature
, Rationale: Interpass temperature is the temperature of the weld area
between weld passes. It must be controlled within specified limits to ensure
proper weld quality and mechanical properties.
9. Which welding process normally uses a nonconsumable tungsten
electrode?
A. SMAW
B. GTAW
C. GMAW
D. FCAW
Rationale: Gas Tungsten Arc Welding (GTAW), also known as TIG welding,
uses a nonconsumable tungsten electrode to establish and maintain the arc.
Filler metal may or may not be added depending on the application.
10. What is the primary purpose of an effective weld length requirement?
A. To identify the welder's qualification range
B. To establish the portion of the weld that can be relied upon for the
intended structural resistance
C. To determine the electrode classification
D. To determine the base-metal chemical composition
Rationale: Weld length directly affects the available load-carrying capacity of
a connection. Structural design provisions distinguish between total physical
weld length and the length that can appropriately be credited for resistance.
11. During tempering, as the temperature increases, which of the following
occurs?
A. Hardness increases
B. Hardness decreases
