Uniform heating of a welded component to a temperature sufficient to relieve a major portion of the residual stresses.

The reheating of a weldment to a temperature below the transformation temperature and holding it for a specified period of time. A frequently used temperature and time is 1150øF. for 1 hr. per inch of thickness. This reheating removes most of the residual stresses put in the weldment by the heating and cooling during welding.

A straight weld bead opposed to a weaving bead. In surfacing, the weaving bead produces less dilution because the weld puddle is always in contact with the part of the bead produced on the previous oscillation rather than the base metal.

The short length of filler metal electrode, welding rod, or brazing rod that remains after its use for welding or brazing.

In arc welding, a type of metal transfer in which molten filler metal is propelled axially across the arc in small droplets.
