FREE Certified Welder Blueprint Reading and Symbols Questions and Answers

Question 1

On a standard AWS welding symbol, where would you find information specifying the welding process to be used, such as GMAW or FCAW?

Accepted Answer

In the tail of the symbol

Answer

The tail of the welding symbol is used to convey supplementary information, including the specific welding process, electrode type, or relevant specifications that are not part of the main symbol elements.

Question 2

A blueprint shows a fillet weld symbol (a right triangle) placed above the solid horizontal reference line. What does this indicate to the welder?

Accepted Answer

The weld must be made on the side of the joint opposite from where the arrow is pointing.

Answer

According to AWS standards, information placed above the reference line refers to the 'other side' of the joint, which is the side opposite to where the arrow is pointing. Information below the line refers to the 'arrow side'.

Question 3

A welder is reviewing a blueprint for an on-site construction project. They notice a symbol that looks like a small flag at the junction of the arrow and the reference line. What does this 'field weld' symbol signify?

Accepted Answer

The weld must be completed at the construction site, not in the fabrication shop.

Answer

The field weld symbol, which resembles a flag, indicates that the weld is to be made 'in the field'—that is, at the location of final assembly or erection—rather than in the initial fabrication shop.

Question 4

When interpreting a symbol for an intermittent fillet weld, two numbers are shown to the right of the weld symbol, such as '2-6'. What does the second number ('6') represent?

Accepted Answer

The center-to-center spacing, or pitch, of the welds.

Answer

For an intermittent weld, the numbers to the right of the symbol denote the length and pitch. The first number is the length of each weld segment, and the second number is the pitch, which is the distance from the center of one weld to the center of the next.

Question 5

Which of the following supplementary symbols, a circle at the intersection of the reference line and arrow, instructs the welder to perform the weld completely around the entire joint?

Accepted Answer

Weld-All-Around symbol

Answer

The Weld-All-Around symbol is a circle placed at the junction of the reference line and the arrow. It indicates that the specified weld must extend continuously around the entire perimeter of the joint.
