The shortest distance between the weld root and the face of a fillet weld.

Active fluxes produce changes in weld metal chemistry when welding is changed. Active fluxes are restricted to single or minimal multi-pass welding.

Submerged-arc welding flux from which the amount of elements deposited in the weld metal is dependent upon welding conditions, primarily arc voltage.

A weld that meets the applicable requirements

Slag used for cleaning or surface roughening.
