Explanation:

Identify the joint types

The image displays two types of weld joints: a fillet weld (top left) and a groove weld (bottom right).

Define root opening

The root opening is the separation between the members to be joined at the root of the joint. This gap allows the weld to penetrate through the thickness of the joint.

Locate root opening on the diagram

Looking at the groove weld diagram on the bottom right:

• Letter K points directly to the gap or separation distance between the two plates at the root of the joint.
• Therefore, K represents the root opening.
