ET - Testing and services

For testing with ET method electrically conductive material is necessary. For this reason the method is often used for detection of surface gaps in aluminum alloys. It can be:

• detection and evaluation surface and subsurface defects
• structuroscopy and evaluation of material exchanging

Testing process of ET
Different application requires different procedures and criteria. The basic applications are

• metallurgic semi-manufactured product testing on automatic lines by encircling probes or rotating heads (requirements are for example in EN 10 246-1,3)
• testing of heat exchanging tubes by bobbin probes (requirements are for example in ASME V,8 or DIN 25435-6)
• in-service testing of planes by pick-up coils (requirements are in specifications of plane manufactures)
• automatic part testing in automotive industry
• structuroscopy
