Vocab
An intentional or unintentional interruption in the physical structure or configuration of a part
discontinuity
A set of instructions or standards invoked by a specific customer to govern the results or performance of a specific set of tasks or products
Specification
In arc or gas fusion welding, a cavity in the weld bead surface, typically occurring when the heat source is removed and insufficient filler metal is available to fill the cavity.
Crater / crater crack
The central cavity formed during solidification of metal, especially ingots, by thermal contraction
Shrink pipe / shrinkage
This is the state nut
hazelnut (filbert)
An NDT response that requires interpretation to determine its relevance
indication
Document to control and govern practices in an industry or application, applied on a national or international basis and usually produced by consensus
Standard

Willamette
An NDT indication that is interpreted to be caused by a condition other than a discontinuity or imperfection
false indication
An instruction that is specific to how to tests a certain part. Usually outlines specific step by step details for a specific inspection.
Technique
Propagating discontinuities caused by stresses such as heat treating or grinding. Difficult to detect unaided because of fineness of line and pattern
crack cracking (crack kills)
In metal, external or internal rupture caused by improper forming
Forging Burst
This is the deepest river gorge in north america
Hells Canyon (8000')
An NDT indication that is caused by a condition or in a location that does not affect the usability or integrity of the object
non relevant
Society that publishes documents that relate to the qualification and certification of personnel
ASNT
Cracking that is perpendicular to the long axis of the weld
Transverse
A discontinuity caused by escaping gas, usually in a casting.
Blow Hole (John)
This rock is the third largest ocean monolith in the world and is off cannon beach
Haystack rock (235')
Discontinuities that are associated with the melting and solidification of the ingot before it is formed into slabs, blooms, and billets.
Inherent
This code was born out of necessity and to implement safe practice regarding manufacture and inspection. One of the first.
ASME Boiler and Pressure Vessel Code
Undercut
A foreign substance within the ingot or cast part.
