Chapter 11, Problem 1P

A manufacturing company routinely specifies X�ray radiography to ensure the absence of cracks in its cast metal products. The primary reason for selecting radiography is the availability of a hard�copy record of each inspection for use in any possible liability litigation. Discuss the pros and cons of their selection. What other processes might you want to consider? If some form of permanent record is desirable, discuss how these might be obtained for the various alternative processes.
