What is the method for measuring the size of a flare-groove weld?

Measuring the size of a flare-groove weld involves considering both the throat thickness and the face width. Throat thickness refers to the shortest distance from the root of the weld to the face of the weld, which is critical because it directly affects the strength of the weld. Face width, on the other hand, refers to the width of the weld face, which contributes to the overall appearance and effectiveness of the weld in distributing loads.

Since both these measurements are essential for determining the overall size and quality of a flare-groove weld, evaluating either the throat thickness or the face width is necessary. This ensures that the weld meets the required specifications and standards, providing the necessary structural integrity for the application.

The inclusion of both these parameters allows for a comprehensive assessment of the weld, making it clear why this method is preferred over measuring just one of them or stating that none of the given methods apply.
