A test specimen with the reduction section composed wholly of weld metal.

Slag used for cleaning or surface roughening.

A weld that meets the applicable requirements

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

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