Final answer:
A weld face is an indication of good weld penetration.
Explanation:
On the back of a weld, a weld face is an indication of good weld penetration.
A weld face is the side of the weld that is exposed to view. It should appear smooth and uniform, indicating that the filler metal has adequately penetrated the joint and achieved a strong bond between the two pieces being welded.
If there is a burn mark, plug weld, or stitch weld on the back of the weld, it does not necessarily indicate good penetration.
