question 2 of 10
identify the weld size using these images
b
d
k
h
c

Explanation:

Analyze the fillet weld diagram

The first diagram shows a fillet weld on a lap joint. In a fillet weld, the weld size is determined by the leg length of the largest right triangle that can be inscribed within the fillet weld cross-section.

• B and C represent the leg lengths of the fillet weld.
• A represents the theoretical throat.
• D represents the actual throat.
• E represents the joint root.
• F represents the root penetration.

Therefore, the weld size for a fillet weld is represented by its leg lengths, which are labeled as B and C. Looking at the multiple-choice options, C is listed as one of the choices.

Analyze the groove weld diagram

The second diagram shows a groove weld preparation.

• G represents the groove depth.
• H represents the groove angle.
• I represents the bevel angle.
• J represents the groove face.
• K represents the root opening.
• M represents the root face.

For a groove weld, the weld size (or joint penetration) is typically related to the depth of preparation plus any root penetration. However, the standard representation of fillet weld size is directly given by the leg length, which corresponds to C (or B) in the first diagram.

Match with options

The available options on the left are:

• B
• D
• K
• H
• C

Since C represents the vertical leg length (weld size) of the fillet weld, C is the correct identifier for the weld size among the given choices.

Answer:

• B
• D
• K
• H
• C (Correct answer)
