Inidam can either carry out MPI NDT at it’s laboratory in Romsey, Hampshire or at the client’s premises. In the laboratory the NDT technicians can utilise either of two fixed instillation bench units: A Granier 6000 Amp and an Emcol 1500 Amp set, both containing Chemetall Lumor 3X fluorescent ink. Components up to 4m in length can be examined using the wet continuous fluorescent method in current flow, coil, thread bar, and flexible cables. Also available are portable Johnson & Allen electromagnetic yokes. The laboratory can process one- off specially manufactured components or handle large production volumes of work.
On site Inidam NDT inspectors are available at short notice to carry out MPI using Chemetall Black Ink and Chemetall White Contrast Paint or Chemetall Fluorescent Ink and a portable UV-A light. Due to it’s versatility a large volume of MPI testing can be carried out using an electromagnetic yoke. The equipment is small and extremely portable.
The team at Inidam are committed to providing a high level of service and consider meeting the exact requirements of the client a priority. Communication between the client’s representatives and Inidam’s NDT inspectors, whether on site or in the laboratory is imperative to the successful conclusion of any work undertaken.
The MPI process puts a magnetic field into the part. The piece can be magnetised directly or indirectly. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or a form of direct current (DC) (rectified AC).
