Welder Red Seal · Question
A blueprint for a pipe joint specifies a single-V-groove weld. The weld symbol shows a '60°' inside the V-groove symbol on the reference line, and '2' mm for the root opening. What does the '60°' represent?
For groove welds, numerical values placed within the groove symbol itself, like '60°' in a V-groove, indicate the included angle of the groove preparation. This

Question: A blueprint for a pipe joint specifies a single-V-groove weld. The weld symbol shows a '60°' inside the V-groove symbol on the reference line, and '2' mm for the root opening. What does the '60°' represent?
Answer options:
- The leg length of the weld ✅ The included angle of the groove
- The approach angle for the welding electrode
- The angle of distortion allowance
Correct answer: The included angle of the groove
Explanation: For groove welds, numerical values placed within the groove symbol itself, like '60°' in a V-groove, indicate the included angle of the groove preparation. This is crucial for joint fit-up and ensuring proper fusion during welding. The root opening is specified separately.
