Visual testing (VT)
Visual inspection to EN ISO 17637, before, during and after welding: edge preparation, alignment, bead appearance, undercut, excess reinforcement and surface defects, under the lighting and access conditions the standard requires.
Penetrant testing (PT)
Detection of surface-breaking discontinuities in non-ferromagnetic materials, particularly stainless steels and alloys, with documented product selection and penetration and development times.
Magnetic particle testing (MT)
Detection of surface and near-surface discontinuities in ferromagnetic materials, with control of magnetisation directions and verification of system sensitivity.
Ultrasonic testing (UT)
Volumetric examination of joints to detect and size internal discontinuities, with recorded calibration and evaluation against the applicable acceptance criteria.
A report with a verdict
Every finding is documented with its location, size, method, acceptance criteria and decision. It is a document that stands up in an audit, not a photograph with a comment.
