Exam of plates, welds, alloys and HAZ (zones thermally affected by the heat (HAZ) and their adjacencies) of practically all metallic materials used in industries such as carbon steel, low alloy steel, austenitic stainless steel, aluminum, copper and titanium (and their alloys) in practically all types of metallic equipment such as pressure vessels, boilers, pipe, aircrafts, bridges, petroleum platforms, submarines and big metallic structures.
The technique is versatile and the equipment used for exam in field is light, resistant and practical, which allows its application in places of difficult access, from small openings and holes to submarine inspections. There is a big variety of probes and cables up to 100 meters long. The exam can be carried out on painted surfaces and on surfaces without strict preparation, besides dismissing utilities such as electrical power, compressed air and water in the local of exam. The eddy-current method is approved by the European Community and qualified by PNC and ASNT. The is carried out according to EN BS 1711:2000 standard and ASME V article 8.
The main advantages are:
- Less demanding preparation of surface
- It does not require painting removal
- It does not require consumable
- It does not require utilities (water, energy or compressed air)
- Fast, clean and efficient process
- Faster than magnetic particles and dye penetrant
- It allows register of calibration and inspection and consequently, of follow up of evolution of discontinuities
- Advantages under ACFM testing /Dye penetrant and Magnetic Particles (See additional documents “ACFM x EC” and “EC xPM-LP”.
