A form of surfacing in which one or more layers of weld metal are deposited (for example, a high alloy weld deposit on steel base metal which is to be welded to a dissimilar base metal). The buttering provides a suitable transition weld deposit for subsequent completion of the butt weld on the groove face of one member.

Process of cutting material to size for more manageable processing.
A defect in metal caused by hot metal cooling too rapidly when excessive gaseous content is present. Specifically, in welding, a gas pocket in the weld metal resulting from the hot metal solidifying without all of the gases having escaped to the surface.
Bonded fluxes are manufactured by binding an assortment of powder together and then baking at a low temperature. The major advantage is that additional alloying ingredients can be added to the mixture.
A weld produced by heating an assembly to the brazing temperature using a filler metal having a liquidus above 450 deg C (840 deg F) and below the solidus of the base metal. The filler metal is distributed between the closely fitted faying surfaces of the joint by capillary action.
