Which of the following statements about brazing strength ratings is true?

Wider fit ups produce stronger joints
Proper fit up is crucial for high strength ratings
Higher temperatures always increase strength
Chemicals used do not affect strength

The correct answer is: Proper fit up is crucial for high strength ratings

The statement that proper fit-up is crucial for high strength ratings is true because the fit-up between the components being brazed directly affects the quality and integrity of the joint. A good fit-up allows for better capillary action, which is essential for the molten filler metal to flow into the joint and properly bond the materials together. When the joint gap is too wide or inconsistent, it can result in weak spots and insufficient adhesion, leading to a lower strength rating. Proper alignment and fit also facilitate even heating during the brazing process, promoting a more uniform joint and minimizing the risk of defects. This principle highlights the importance of precision in assembling the components before brazing takes place to ensure optimal joint strength.
