What is the recommended bevel angle when repairing a frame component?

• A. 15 degrees on each side
• B. 30 degrees on both sides
• C. 45 degrees on each side
• D. 60 degrees on both sides

Answer: (B)

When repairing a frame component, the recommended bevel angle of 30 degrees on both sides is optimal because it allows for effective welding and structural integrity. A 30-degree bevel provides a good balance between sufficient surface area for weld penetration and a manageable amount of material to remove, ensuring a stronger joint. The angle is steep enough to create a strong weld while being shallow enough to avoid excessive removal of material, which could weaken the frame. Choosing a bevel angle that is too shallow may not allow for adequate penetration of the weld, leading to a weak joint. Conversely, a bevel that is too steep could compromise the frame's strength and unnecessarily increase the complexity of the repair process. Thus, the 30-degree angle on both sides strikes a practical compromise, facilitating a strong and reliable repair.
