A weld cap is excessively high above the pipe surface. This condition may: A. Cause stress concentration B. Improve weld quality C. Eliminate the need for NDE D. Increase corrosion resistance. correct answer

Here's the answer to your question:

A weld cap is excessively high above the pipe surface. This condition may:

• Explanation: An excessively high weld cap, also known as excessive reinforcement, creates an abrupt change in the geometry of the weld joint. This sudden change in contour acts as a stress riser, meaning that stresses will concentrate at this point when the pipe is under load. Stress concentration can lead to premature fatigue failure or brittle fracture, especially under cyclic loading or in environments with high internal pressure. It does not improve weld quality, eliminate NDE, or increase corrosion resistance.

• Answer: The correct option is A. A. Cause stress concentration
