WCL Joint Design & Weld Symbols

Question 1

In AWS welding symbols, a weld symbol placed BELOW the reference line indicates the weld should be placed on which side?

Accepted Answer

The arrow side

Answer

A weld symbol below the reference line indicates the weld is on the arrow side — the side the arrow physically points to.

Question 2

What type of weld joint is formed when two members are placed end to end in approximately the same plane?

Accepted Answer

Butt joint

Answer

A butt joint is formed when two members are aligned end to end (or edge to edge) in the same plane, requiring groove welds.

Question 3

Which symbol represents a fillet weld in AWS welding symbols?

Accepted Answer

A right triangle

Answer

A fillet weld is represented by a right-triangle symbol on the welding symbol, reflecting its triangular cross-sectional shape.

Question 4

On an AWS welding symbol, where is the weld-all-around symbol placed?

Accepted Answer

At the junction of the arrow and reference line

Answer

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.

Question 5

What does a flag (pennant) symbol on a welding symbol indicate?

Accepted Answer

Field weld

Answer

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.
