Question

identify the root opening using these images of a fillet weld and groove weld

k
d
h
c
b

Explanation:

Analyze the groove weld diagram

The diagram on the right shows a groove weld joint preparation. The labels indicate different geometric features of the joint:

• G represents the root face.
• H represents the groove angle.
• I represents the bevel angle.
• J represents the groove face.
• K represents the separation between the members at the joint root, which is the root opening.
• M represents the plate thickness.

Identify the root opening

The question asks to identify the "root opening" using the provided images. Based on standard welding joint geometry, the root opening is the gap or distance between the workpieces to be joined at the root of the joint. In the groove weld diagram on the right, this gap is labeled with the letter K.

Answer:

• (A) K (Correct answer)
• (B) D
• (C) H
• (D) C
• (E) B
