Eddy-current Weld Inspection

We now offer detection of surface cracks using Eddy current and have Level 2 qualified technicians, this is great to use without the removal of paint! - great cost savings in time and money especially on EWP major 10/5 year certifications and Crane inspections. IANZ endorsed reports can also be issued if required.

Eddy-current inspection is applied to welds using specialist probes and is not as messy as Dye Penetrant or Magnetic Particle inspection. Big cost savings can be made by not having to remove the paint.

Phase Array Weld Inspection

We offer full manual Phase Array flaw inspection of welds, this method of ultrasonic inspection fastly improves the time and ability to interpret flaws in welds than the traditional UT A scan method.

Gamma Radiography

Dont forget DE has both Gamma and Xray equipment to inspect welds in pipes and plates including an ultra light weight x-ray tube that only weighs 9kg.
