In welding position notation, when using a number (e.g., 1F), it refers to ______ and when using single words (e.g., horizontal or vertical) it refers to ______.

• A. Testing/Production
• B. Production/Testing
• C. Both
• D. Neither

Answer: (A)

In welding position notation, numbers are used to identify testing or qualification positions on a coupon, while the descriptive words like horizontal or vertical refer to actual production welding positions. The numeric designation (for example, 1F) signals a test setup used for certification or qualification, whereas using terms such as horizontal or vertical describes how a weld is made in production. So the first blank is Testing, and the second blank is Production.
