This course covers the principles of Liquid Penetrant Testing and prepares a candidate to

• Select equipment to conduct test
• Setup test equipment
• Steps to conduct test
• Familiarize with codes and standards
• Interpret results with respect to applicable codes and standards • Understand limitation of the test method
• Write test reports.

This course will combine presentations with interactive practical exercises, supported by video materials, activities and case studies. 

 PROGRAMME SUMMARY

This course contains Level 1 and 2 material and covers the theories and practices involved with liquid penetrant inspection. Equipment, light meters, code & procedure reference, types, forms, and methods are discussed.

Day 1 –Dye penetrant test (PT)-General

 Purpose of Liquid Penetrant Testing /Physical Principles /Wetting Ability and Contact Angle/ Capillary Action/Viscosity/Reversed Capillary Action/ Types of Dye: Type I (Fluorescent) and Type II (Visible)/Methods of Removal of excess Penetrant including Water Washable, Emulsifiers and Solvent Removable.
