An arc spot procedure qualification test has been successfully performed on steel decking in the flat position. For what angle range will this test qualify the procedure?

• A. Flat to horizontal positions
• B. Only the flat position
• C. Flat to vertical
• D. Any angle

Answer: (A)

The key idea here is that a procedure qualification test validates the welding parameters for the positions actually tested. If the arc spot test was completed in the flat position on steel decking, the approved procedure is considered qualified for welding in flat to horizontal positions. That means you can use the same procedure for welds made in the flat and in the horizontal orientations, but not for vertical or overhead positions unless separate testing is done. The reason is that changing to vertical or overhead affects puddle control, heat input, and weld quality, so those positions require their own qualification.
