Short Seam Width
Cross Section Double Seam Defects - Cause & Remedy

A Short Seam Width will be noticeably loose between layers of the metal when viewed through a seam projector. The compilation of five layers of material compared to the actual seam thickness will measure differently. This type of seam will leak because the folds of metal are not compressed together tight enough not allowing compound to fill the voids.
