1. Which organization publishes the AWS D1.5 Bridge Welding Code?
A) ASME
B) API
C) AWS
D) ISO
Answer: C
The American Welding Society (AWS) is the organization responsible for
publishing the D1.5 Bridge Welding Code.
2. What is the primary purpose of a backing bar in groove welds?
A) To increase weld size
B) To support molten metal and prevent burn-through
C) To reduce heat input
,D) To improve weld appearance
Answer: B
A backing bar provides support for the molten weld pool and prevents burn-
through, especially on thin materials.
3. Which welding process is most commonly used in bridge construction per AWS
D1.5?
A) Oxy-fuel welding
B) SMAW (Shielded Metal Arc Welding)
C) GTAW (TIG)
D) Laser welding
Answer: B
SMAW is widely used in structural bridge welding due to its versatility and
suitability for field conditions.
4. What is the maximum allowable preheat temperature for carbon steel thicker
than 2 inches?
A) 100°F
B) 200°F
C) 300°F
D) 400°F
Answer: C
,AWS D1.5 specifies preheat up to 300°F for thick carbon steel to avoid cracking.
5. What type of joint is typically used for bridge girders?
A) Lap joint
B) Butt joint
C) Tee joint
D) Corner joint
Answer: B
Butt joints are commonly used in bridge girders to join plates edge-to-edge.
6. What is the primary purpose of a welding procedure specification (WPS)?
A) To define visual inspection standards
B) To describe the welding process, parameters, and materials
C) To certify welders
D) To specify paint requirements
Answer: B
A WPS ensures consistent, high-quality welds by providing specific instructions
for welding.
7. When welding in the flat position, what is the typical electrode angle?
A) 0-10°
B) 15-30°
C) 45-60°
, D) 60-75°
Answer: B
A slight electrode tilt helps control the weld pool and reduce spatter in flat welding.
8. What is the typical travel speed for SMAW on 1/2-inch steel?
A) 1-2 in/min
B) 3-6 in/min
C) 8-12 in/min
D) 15-20 in/min
Answer: B
Maintaining proper travel speed ensures adequate fusion and prevents defects.
9. Which inspection method is required for critical bridge welds?
A) Visual inspection only
B) Ultrasonic testing, radiographic testing, or magnetic particle testing
C) Surface roughness measurement
D) Hardness testing
Answer: B
Critical welds in bridges often require NDT to detect internal or surface flaws.
10. What is the minimum root opening recommended for a single V-groove weld
on 1-inch steel?
