Which of the following is NOT a feature of acceptable fillet weld profiles?

• A. Flat faced
• B. Concave
• C. Convex
• D. Sharp angled

Answer: (D)

A fillet weld profile refers to the shape and contour of the weld joint between two pieces of metal. A proper fillet weld should provide adequate strength and meet specific design criteria, which include geometry and surface characteristics crucial for performance under load. Acceptable fillet weld profiles like flat faced, concave, and convex are all deemed appropriate as they can effectively distribute stress and are conducive to proper binding between materials. These profiles also allow for effective penetration and bonding across the joint, contributing to the overall strength and durability of the weld. In contrast, a sharp-angled profile is not considered an acceptable feature of a fillet weld. Sharp angles can create stress concentrations and are more prone to defects, leading to potential failure under load. Such profiles do not promote a gradual transition between the welded materials, which is critical for maintaining integrity and performance in structural applications. Therefore, the option indicating sharp-angled profiles correctly identifies a feature that does not meet the standards for acceptable fillet weld profiles.
