Destructive testing is testing that damages or destroys the part. Because destructive testing changes the part, or even destroys it, during testing, replication is not possible.
For example, tests of welds that are destructive include impact tests, fracture tests, and corrosion tests.
If destructive testing is too expensive, use a non-destructive test. For example, tests of welds that are non-destructive include dye penetration tests, gamma-radiography tests, and acoustic emission tests.
