Chemical Etch (Macro-Etching) - Level 3
(5 Days)

COURSE DESCRIPTION:
This advanced course to cover chemical macro-etching of a range of widely used engineering metals to level 3 using the model of level 3 training for the five main methods of NDT as described in BS EN ISO 4179. The course covers the general metallurgy and chemistry of macro-etching in considerable detail so the students obtain a wide knowledge of different metals and alloys which prepares them for the responsibility of ensuring that the optimum process or processes are applied. The term “Chemical Etching” is used in preference to the commonly used “Acid Etching” since some alloys may be etched in either acid or alkaline solutions.

  • Atomic Structure & Bonding
  • Electrochemistry
  • Heat Treatment & Properties of Materials
  • Use of Chemical Enchants
  • General Etching Procedures
  • Health, Safety and the Environment

APPLICABLE REFERENCE STANDARDS AND DOCUMENTS:
This training program was developed to meet the commercial, aerospace and customer requirements to include: BS EN ISO 4179.
