Case Study – Use of SPOTCHECK® SKL-WP2 for inspecting welded fabrications
Our customer is one of the largest engineering and fabrication companies in the UK. The employ around 600 staff across 14 divisions, operating in many different industries including aerospace and defence, oil and gas, nuclear, mining, and automotive. Within their Fabrication Division, they carry out non-destructive testing using visible red dye penetrant to check for defects associated with welds.
The customer had some concerns about the current visible red penetrant that they were using; it was running off the areas to be inspected and not allowing any defects to be detected. They needed to find a visible red penetrant system that met with their technical requirements, and which they could source locally. They wanted to evaluate the equivalent penetrants from a number of UK suppliers, including Magnaflux EMEAR.
Our direct product equivalents to what they had been using were SPOTCHECK® SKC-S (solvent-based cleaner and remover), SPOTCHECK® SKL-WP2 (solvent-removeable and water-washable penetrant) and SPOTCHECK® SKD-S2 (solvent-based developer). We sent aerosol samples of all three products, along with the applicable Product and Safety Data Sheets, to our customer to support their evaluation process.
Magnaflux EMEAR has a comprehensive distributor base within the UK, so we were able to give our customer the choice of two geographically-close distributors from whom they could purchase our products.
Our customer carried out a side-by-side evaluation of a number of visible red penetrant systems from different suppliers. Whilst the results of the testing were not dissimilar the results obtained with the SPOTCHECK range of products were better. Specifically, SPOTCHECK SKL-WP2 showed red indications on welds which exhibited surface breaking defects. The use of SPOTCHECK SKD-S2 solvent-based development enhanced the visibility of these indications, allowing decisions to be made quickly on any identified faults.
They are now sourcing the products through a distributor that is ca. 50 miles from their plant and have no issues in obtaining stock to meet their demand needs.

“We have been impressed with the level of service and support provided by Magnaflux EMEAR, including product advice/recommendations, provision of samples/product documentation to follow up support. We have now extended the use of Magnaflux EMEAR products to magnetic particle inspection consumables (MAGNAVIS® 7HF and MAGNAVIS® WCP-2) within a second facility in the UK.”
