In AWS welding symbols, a weld symbol placed BELOW the reference line indicates the weld should be placed on which side?
Answer: The arrow side
A weld symbol below the reference line indicates the weld is on the arrow side — the side the arrow physically points to.
What type of weld joint is formed when two members are placed end to end in approximately the same plane?
Answer: Butt joint
A butt joint is formed when two members are aligned end to end (or edge to edge) in the same plane, requiring groove welds.
Which symbol represents a fillet weld in AWS welding symbols?
Answer: A right triangle
A fillet weld is represented by a right-triangle symbol on the welding symbol, reflecting its triangular cross-sectional shape.
On an AWS welding symbol, where is the weld-all-around symbol placed?
Answer: At the junction of the arrow and reference line
The weld-all-around symbol (a small circle) is placed at the junction where the arrow meets the reference line to indicate continuous welding around the entire joint perimeter.
What does a flag (pennant) symbol on a welding symbol indicate?
Answer: Field weld
A flag or pennant symbol on the welding symbol indicates the weld is to be made in the field (on-site) rather than in the fabrication shop.
In a T-joint, at what angle do the two members typically meet?
Answer: 90 degrees
A T-joint is formed when one member meets the face of another at approximately 90 degrees, creating a T-shape that is typically joined with fillet welds.
On a welding symbol, the number to the LEFT of the fillet weld triangle symbol represents what dimension?
Answer: The weld size (leg length)
The number to the left of the weld symbol represents the weld size — for fillet welds, this is the leg length of the triangular cross-section.
