Q1On a welding symbol, what does it mean when the symbol is placed below the reference line?
✓ Correct answer: D. The weld should be made on the arrow side of the joint
When a welding symbol is placed below the reference line, it indicates that the weld should be made on the arrow side (the side to which the arrow points) of the joint. This is a fundamental principle of reading welding symbols that helps communicate where the weld should be located.
Q2What does a circular symbol placed at the intersection of the arrow and reference line indicate?
✓ Correct answer: C. A spot weld
A circular symbol at the intersection of the arrow and reference line indicates a spot weld. This is commonly used in resistance welding to specify where spot welds should be placed.
Q3What information would typically be found in the tail of a welding symbol?
✓ Correct answer: B. Welding process specifications or reference information
The tail of a welding symbol is used to provide supplementary information such as welding process specifications, welding procedures, references to notes, or specific requirements that cannot be conveyed by the standard symbols alone.
Q4What does a flag at the junction of the arrow and the reference line signify?
✓ Correct answer: A. Field weld
A flag (a small triangular symbol) at the junction of the arrow and reference line indicates a field weld, meaning the weld is to be performed at the job site rather than in a fabrication shop.
Q5How is the size of a spot weld indicated on a welding symbol?
✓ Correct answer: D. To the left of the spot weld symbol
The size (diameter) of a spot weld is indicated to the left of the spot weld symbol. This dimension specifies the diameter of the weld nugget that should be formed during the resistance welding process.
Q6What information is conveyed when numbers are placed to the right of a seam weld symbol?
✓ Correct answer: C. Length and pitch of the weld
Numbers placed to the right of a seam weld symbol indicate the length of the weld and the pitch (center-to-center distance) of increments in an intermittent seam weld, typically expressed as 'length-pitch' (e.g., '2-6' means 2 inches of weld spaced 6 inches apart).
Q7What does a circle around the intersection of the reference line and arrow indicate?
✓ Correct answer: B. All-around weld
A circle around the intersection of the reference line and arrow indicates an all-around weld, meaning the weld continues completely around the joint or feature.
Q8In projection welding symbols, how is the number of projections indicated?
✓ Correct answer: A. Above or below the weld symbol, depending on projection location
In projection welding symbols, the number of projections is indicated above or below the weld symbol, depending on which side of the joint the projections are on. This information is critical for proper setup of projection welding operations.
Q9What does it mean when there is no arrow or other side significance shown on a welding symbol with a resistance spot weld symbol?
✓ Correct answer: D. The weld can be made from either side as resistance spot welds typically penetrate through the material
When there is no arrow or other side significance shown on a resistance spot weld symbol, it means that the location of the weld is not important or is obvious from the context. The weld can be made from either side as it will penetrate through the material.
Q10Which of the following is a typical destructive test method for resistance spot welds?
✓ Correct answer: C. Peel test
The peel test is a common destructive test method for resistance spot welds where the two welded sheets are pulled apart to examine the nugget size and failure mode.
