For brazing, what fit up produces the highest strength ratings?

0.010-0.015"
0.001-0.005"
0.020-0.025"
0.005-0.010"

The correct answer is: 0.001-0.005"

The fit-up that produces the highest strength ratings in brazing is characterized by a clearance of 0.001-0.005". This tight fit allows for optimal capillary action during the brazing process, enabling the filler metal to efficiently flow into the joint and create a strong bond. A minimal gap ensures that the filler metal has the opportunity to fill the joint completely and consistently, minimizing the risk of voids or weak points. In contrast, larger clearances can lead to issues with the integrity of the joint. For instance, gaps greater than 0.005" may cause insufficient flow of the filler metal, leading to weak, porous joints. A clearance in the range of 0.010-0.015" or 0.020-0.025" does not provide the same degree of capillary action required for effective bonding, ultimately resulting in lower strength ratings. Therefore, the 0.001-0.005" fit-up is considered ideal for achieving maximum strength in brazed joints.
