How do brazing and soldering differ from the solid-state welding processes?

What is the technical difference between brazing and soldering?

Under what circumstances would brazing or soldering be preferred over welding?

What are the two joint types most commonly used in brazing?

Certain changes in joint configuration are usually made to improve the strength of brazed joints. What are some of these changes?

The molten filler metal in brazing is distributed throughout the joint by capillary action. What is capillary action?

What are the desirable characteristics of a brazing flux?

Best clearances between surfaces in brazing are which one of the following: (a) 0.0025-0.025 mm (0.0001-0.001 in.), (b) 0.025-0.250 mm (0.001-0.010 in.), (c) 0.250-2.50 mm (0.010-0.100 in.), or (d) 2.5-5.0 mm (0.10-0.20 in.)?

Which of the following is an advantage of brazing (three best answers): (a) annealing of the base parts is a by-product of the process, (b) dissimilar metals can be joined, (c) less heat and energy required than fusion welding, (d) metallurgical improvements in the base metals, (e) multiple joints
can be brazed simultaneously, (f) parts can be readily disassembled, and (g) stronger joint than welding?
