THE COMPLEXITY AND EXPENSE OFTODAY'S MACHINES, EQUIPMENT AND TOOLS DICTATE THE USE OF FABRICATION AND TESTING PROCEDURES THAT WILL ENSURE MAXIMUM RELIABILITY. NONDESTRUCTIVE TESTING PROVIDES MANY OF THESE PROCEDURES. OF THE NUMBER OF NONDESTRUCTIVE TESTING PROCEDURES AVAILABLE, "LIQUID PENETRANT INSPECTION" IS ONE THAT IS WIDELY USED.
INDUSTRIAL APPLICATIONS...
Because of the basic characteristics of Liquid Penetrant Inspection, it is used to test a variety of both metallic and nonmetallic materials such as welds, forgings, castings, plastics, ceramics, etc. Since Liquid Penetrant Inspection is capable of economically revealing surface discontinuities (variations in material composition) in a variety of dissimilar materials, it is an extremely effective and useful tool for inspectors and quality assurance personnel.
TEST PROCEDURES...
Approved procedures for "PT" are formulated from analysis of the test specimen or article, review of its past history, experience on like or similar specimens, and information available concerning discontinuities in similar articles. It is the responsibility of personnel conducting the test to ensure that test procedures are adequately performed, and that the test objective is accomplished.
TEST OBJECTIVE...
The objective of Liquid Penetrant Inspection is to ensure product reliability by providing a means of:
PERSONNEL...
It is imperative that personnel responsible for "PT" be trained and highly qualified with a technical understanding of the test equipment and materials, the item under test, and the test procedures. To make optimum use of "PT", personnel conducting tests must continually keep abreast of new developments. There is no substitute for experience and knowledge. All Halkin personnel are certified in compliance with ASNT and ASTM guidelines, and Halkin's Quality Assurance Manual is available for your review on request.
