Q:
|
What types of filler metal forms are there?
|
A:
|
Filler metals come in wire, strip, powder, or paste form. Availability in these forms depends on the alloy that is chosen. Preforms can be made from strip and wire.
|
Q:
|
What is oxidization?
|
A:
|
When metals are exposed to oxygen, oxides form from oxygen atoms that attach to the metal. The oxides that form prevent the molten alloy from metallurgically joining to the metal.
|
Q:
|
What is Flux?
|
A:
|
Flux is a chemical compound that is applied and shields the joint surface from air and prevents oxide formation. Although flux will dissolve and absorb oxides, the metals that are being joined should be properly cleaned prior to brazing.
|
Q:
|
What are the available flux forms?
|
A:
|
Flux is available from Lucas-Milhaupt in paste, slurry, liquid and powder form depending on the type of flux. Paste, slurry, and liquid fluxes are all water based while dispensable fluxes are petroleum based. Flux can also be delivered to the joint through the torch that is being used.
