AWS AWS Joint Design & Weld Symbols 2 — Questions and Answers
Question 1: On a welding symbol, the reference line is:
- A vertical line connecting to the weld symbol
- A horizontal line with an arrow on one end (Correct answer)
- A dashed line indicating the weld area
- A circle at the junction of the arrow and reference line
Correct answer: A horizontal line with an arrow on one end
The reference line is the horizontal line that forms the base of the welding symbol, with an arrow on one end pointing to the joint location.
Question 2: Weld symbols placed BELOW the reference line indicate:
- The weld is on the far side of the joint from the arrow
- The weld is on the arrow side of the joint (Correct answer)
- The weld is a full penetration weld
- The weld requires preheat
Correct answer: The weld is on the arrow side of the joint
Weld symbols placed below the reference line indicate the weld is on the arrow side of the joint.
Question 3: The tail of a welding symbol is used to indicate:
- The length of the weld
- Welding process, specification, or other supplementary information (Correct answer)
- The weld root opening
- The number of weld passes required
Correct answer: Welding process, specification, or other supplementary information
The tail of the welding symbol is used to specify the welding process, procedure specification, or other supplementary information.
Question 4: What does a circle at the intersection of the arrow and reference line indicate?
- A full penetration weld
- A plug weld
- Weld all around (Correct answer)
- A field weld
Correct answer: Weld all around
A circle at the intersection of the arrow and reference line indicates that the weld is to be made all around the joint.
Question 5: A flag symbol at the junction of the arrow and reference line indicates:
- Weld all around
- A field weld (Correct answer)
- A full penetration weld
- A seal weld
Correct answer: A field weld
A flag symbol at the junction indicates the weld is to be made in the field (on-site) rather than in the shop.
Question 6: In AWS welding symbols, the fillet weld symbol resembles:
- A right triangle (Correct answer)
- A semicircle
- A rectangle
- An X shape
Correct answer: A right triangle
The fillet weld symbol is a right triangle, representing the cross-sectional shape of a fillet weld.
