The questions are about brazing and soldering.
3. How does braze/solder thickness (joint clearance)
theoretically affect joint strength and why?
4. Explain the purpose of Flux in a soldering
application?
3.the thickness should be in the range of 75-100 micrometers for better joint strength..if the thickness is low means the wetting area of joint decreases as the entrapment of fluxes occurs in limited area of thickness..so thus ideal thickness should be maintsined.
4. It removes oxidized material present on the surface of material.
Prevents oxidation of metal and improves wetting characterstics..
