Answer

concentrations of stresses along the backing strip Explanation 1. Identify the cause of weld failure Leaving a backing strip on a weld can lead to failure primarily due to **concentrations of stresses along the backing strip**. This stress concentration can create weak points in the weld, leading to potential failure under load.
