Q1On a welding symbol, what does it mean when the symbol is placed below the reference line?
Show answer
✓ Correct answer: 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?
Show answer
✓ Correct answer: 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?
Show answer
✓ Correct answer: 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?
Show answer
✓ Correct answer: 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?
Show answer
✓ Correct answer: 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?
Show answer
✓ Correct answer: 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).
