w/CHANGE 1

When the class is not specified in the contract or on the drawing, Class A will apply.

3.4 Acceptable

Complies with or conforms to the applicable standard or specification.

3.5 Arc strike

Any inadvertent localized heat-affected-zone (HAZ) or change in the contour of the finished weld or adjacent base metal resulting from an arc or heat generated by the passage of electrical energy between the surface of the finished weld or base metal and a current source, such as welding electrodes or magnetic inspection prods.

3.6 Buttering or build-up

The deposition of filler metal on a base metal surface to restore base material or weld surface dimensions, or to interpose a layer of weld metal on the material surface of the joint prior to joining the material members together.

3.7 Cognizant engineering organization

The engineering organization responsible for the design of the welded assembly. (See

6.6)

3.8 Finished weld

Welds which have received final inspection and have been accepted.
