[Webinar] Fundamentals of Liquid Penetrant Testing

This webinar offers some handy tips for beginners who are new to visible dye liquid penetrant testing or for nondestructive testing (NDT) pros who want an easy reference guide to the fundamentals.
The dye penetrant method of inspection is a nondestructive test for defects open to the surface. It may be used on such materials as aluminum, magnesium, brass, copper, cast iron, steel, stainless steel, carbides, stellite, certain plastics and ceramics. The essentials of the method are: penetration of the defect by the Dye Penetrant - removal of the excess Penetrant from the surface - development of the indication - inspection. A deep red indication will mark the defect.
Surfaces should be free of foreign materials and paint. Grease, oils, etc., prevent penetration and should be removed by precleaning with Cleaner/Remover or by solvent degreasing. Scale, sand, dirt, etc. trap penetrant and hinder removal, therefore wire brushing or similar precleaning is necessary. Paint must be removed from areas to be tested.

Defects will be marked by a deep red indication. A line or dotted line marks a crack, lap, forging burst or cold shut. If wide and deep, the indication will grow and spread. Porosity, shrinkage, lack of bond, and leaks will appear as dots or local areas of color. These, too, will grow and spread if the defect is large or extensive.

Developing on the can says indication should show up in 20 minutes. I have seen indications after a few hours of dwell time

[@Magnaflux2010]

Correct, the amount of dwell time will all depend on your governing specifications.

[@alicetee7020]

Your 6 step process is missing oven drying time.
