If camber checking is specified, should camber be checked at multiple points?

• A. Yes, at multiple points
• B. No, only at one point
• C. Camber checking is not required
• D. Only at the center of the weld

Answer: (A)

Camber is the bow or deviation of the weld line along its length, which can vary from one portion of the weld to another due to heat input, restraint, and cooling. When a camber check is specified, you verify camber at multiple points along the weld to ensure the entire length stays within tolerance, not just a single spot. This broader sampling catches variations that could occur toward the ends, center, or other sections, ensuring the weld meets the required straightness across its whole length. Checking only one point could miss camber elsewhere, so measuring at several locations is the proper approach.
