Final answer:
The amount of weld metal required for a fillet weld is equal to the actual throat multiplied by the leg length.
Step-by-step explanation:
The amount of weld metal required for a fillet weld depends on the leg length. As the leg length increases, the amount of weld metal required also increases. Therefore, option a) and option b) can be ruled out.
The throat size of a fillet weld is the shortest distance from the root of the joint to the face of the weld. The amount of weld metal required is not inversely proportional to throat size, so option c) is incorrect.
Option d) states that the amount of weld metal required is determined by the required depth of penetration. This is not accurate. The depth of penetration affects the quality of the weld, but it does not directly determine the amount of weld metal required. Therefore, option d) is incorrect.
Option e) states that the amount of weld metal required is equal to the actual throat multiplied by the leg length. This is the correct answer. The throat size determines the leg lengths, and the amount of weld metal required is proportional to both the throat size and leg lengths. Therefore, option e) is the correct choice.
