Calculate brazed joint clearance, filler metal volume, and expected joint strength for capillary brazing operations
Input Parameters
Results
--
Filler Metal Volume
mm3
--
Filler Metal Mass
g
--
Joint Shear Strength
MPa
--
Max Joint Load
kN
Note: Per AWS C3.3 Brazing Handbook. Optimal clearance is critical - too tight restricts flow, too wide reduces capillary action and strength.
Reference
Brazing Joint Design (AWS C3.3):
Filler volume = perimeter x overlap x clearance x 1.10
Optimal clearance: 0.025-0.125 mm (0.001-0.005 in)
Joint strength peaks at optimal clearance
Shear area = perimeter x overlap length
