What are Secondary Processing and Finishing Discontinuities?

What are Secondary Processing and Finishing Discontinuities?

Secondary processing and finishing discontinuities are associated with the various finishing operations, after the part has been rough formed by rolling, forging, casting or welding.

What are Primary Processing Discontinuities?

What are Primary Processing Discontinuities?

When steel ingots are worked down into usable sizes and shapes such as billets and forging blanks, some inherent discontinuities may appear.

What are In-Service Discontinuities?

What are In-Service Discontinuities?

Service discontinuities are formed or produced after all fabrication has been completed and the part has gone into service.

What are Inherent Discontinuities?

What are Inherent Discontinuities?

While one might assume defects or abnormities occur during a part’s manufacturing process, there are some discontinuities which occur before a part’s creation even starts.

Defects vs. Discontinuities

Defects vs. Discontinuities: Which is Which?

In the world of nondestructive testing, “defect” and its synonyms are not necessarily interchangeable.
