Question

With increasing joint thickness, the tensile strength of a brazed joint

Answer 1

Answer:

Explanation:

One of the most widely used charts in the field of brazing is the strength vs. clearance chart created from work done in the Handy & Harman laboratories in Fairfield, Connecticut back in the 1930’s. This chart is shown below, in Fig. 1:

Notice that as the joint clearance gets tighter and tighter (moving from right to left along the bottom axis), the tensile strength (as shown on the vertical axis on the left-side of the chart) gets higher and higher. Although there is a lot of experience with this over the years, and general acceptance of this information is widespread, it must be pointed out that this chart is very specific only to the actual testing performed in making this particular chart, and may not be identical to tests performed by others using similar materials or conditions. But the general principal of increased joint strength with tighter gaps can be accepted.

What about that strength “drop-off” below 0.0015” (0.04mm) ?

Please notice that something strange happens at the far left of the chart in the area shown by gap-clearances of about 0.0015″ (0.04 mm) or less. There appears to be a drop-off in the tensile strength when the gaps are tighter than 0.0015″ (0.04 mm).
