Discuss the advantages and disadvantage of this technique.

1. Make a sketch of your sample.2. Under the magnifying glasses place each tested samples and investigate carefully anykind of cracks, flaws, discontinuity, etc that might be located on the surface of the testsamples.3. Measure the size of the discontinuity.4. Identify each discontinuity5. Record your observations and include them in the lab report.Questions to be answered in the lab report:• Determine the type of discontinuity.• Determine what caused the imperfection in the weld.• Discuss the advantages and disadvantage of this technique.• Give at least three application for this technique.Writing the laboratory ReportYour report should be typical of an engineering report, typed and include the following:• A brief theory of visual inspection.• Write the test procedures (do not copy the one above but write a procedure according to your own experiment).• Determine the type of discontinuity.• Determine what caused the imperfection in the weld.• Discuss the advantages and disadvantage of this technique.
