Flux types for SAW manufactured by method of manufacture are which of the following?

• A. Fused, Bonded, Agglomerated
• B. Powdered, Pelletized, Coated
• C. Neutral, Acid, Basic
• D. Liquid, Gaseous, Solid

Answer: (A)

In SAW, flux types are defined by how the flux is made. The three recognized forms are fused, bonded, and agglomerated. Fused flux is created by melting the raw materials and then forming granules from the melt, giving a very pure, dense slag. Bonded flux mixes the flux powder with a binder so the mix can be formed into cohesive granules, which aids handling and flow while still forming the protective slag. Agglomerated flux is produced by clumping fine powders into larger granules, often with a binder or moisture, to improve flow and reduce dust. The other options describe forms or properties rather than how the flux is manufactured, so they don’t apply to the classification by manufacture.
