Where is the test all around symbol centered when indicating a field test?

• A. With a statement indicating test all around in the field located in the tail of the reference line.
• B. With a field weld symbol connected to the reference and arrow line intersecting with test all around indicated in the tail.
• C. With a test all around symbol centered where the reference and arrow line intersect with the test in field flag attached to the all around symbol.
• D. With a test all around symbol centered where the reference and arrow line intersect with the test in field flag attached to reference and arrow intersect.

Answer: (C)

The essential idea is how a field requirement is represented on a welding symbol. The test all around indicator applies to the actual weld location, so it must be placed right where that weld is defined—at the intersection of the reference line and the arrow line. When the test is to be done in the field, a field flag is attached to that all-around symbol to show the testing occurs on site, not in a shop. Placing the symbol elsewhere (like on the tail or away from the intersection) would mislocate the requirement or blur which joint is being referenced. So the correct representation centers the test all around symbol at the intersection of the reference and arrow lines, with the field flag attached to that symbol.
