Importance of the use of inspection instruments when surface treating steel structures

There are many ways to access the perfect corrosion protection, and whether you shot blast, metallize or spray paint, the roughness, the purity and the layer thicknesses are all factors that have to be controlled and checked up upon many times during the different processes of surface treatment. Today, far more often, stricter requirements are imposed on documentation and collection of data throughout the anti-corrosion process: for some processes, to a greater extent than others.
Fortunately, it becomes more and more easy to document the whole process, as the different inspection instruments follow the course of technology and development. Moreover, the transfer of data is easier to handle today than ever before.

Measurements with inspection equipment make really good sense within certain areas

In the picture above, we are at a customer, who we have helped to install a automation solution for the metallization of wind turbine tower sections. Our technical team is checking whether the zinc alloy coating has the correct thickness in relation to the customer's specifications.

Measurements with instruments take place within shot blasting, metallization and airless paint. On shot blasted surfaces you typically make measurements of roughness and purity. In addition, salt tests are often carried out to determine whether there are any kind of salt on the steel parts to be surface treated. For our customers, it is primarily about surface treating wind turbine towers, steel structures for offshore use or container parts for maritime freight.

Within zinc/alloy metallization, pull-off testing is often performed to ensure proper adhesion, as well as layer thickness measurement of the zinc/alloy coating to ensure the correct layer thickness specified by the customer.

To be able to control the paint application, it is in particular the paint layer thickness, adhesion and gloss measurement demanding frequent check-ups and control. This is common procedure within epoxy primers and polyurethane based topcoat paints.

Clemco Denmark stocks all types of inspection gages to cover all measurements throughout the anti-corrosion process

Clemco Denmark A/S offer a wide range of inspection gages, primarily from DeFelsko in the United States, for control of the following surface parameters: roughness, dust, salt concentration, adhesion, layer thickness, gloss, pore holes and corrosion.
For more than 50 years DeFelsko have manufactured inspection gages within all processes of surface treatment of magnetic and non-magnetic materials. DeFelsko have always been at the forefront of development and innovation, and during the last couple of years, much has been done to make the inspection for surface treatment as easy as possible. The possibilities are constantly being expanded; with software, apps and new products. DeFelsko has adapted their inspection instruments to the world that surrounds us, with e.g. our smartphone as an indispensable multitool that everyone has in their pocket. The possibilities of being able to meet the stricter requirements for documentation throughout the whole surface treatment process have become easier as the development progresses.

Inspection instruments used for control of quality parameters within surface treatment can be divided in different groups:

  1. Environmental gages
  2. Inspection equipment (flashlights, mirrors and handbooks)
  3. Surface profile gages
  4. Coating thickness gages
  5. Adhesion testers
  6. Gloss meters
  7. Chloride testers

News within inspection gages

Each instrument has its own specific function - or at least that has been the case so far. DeFelsko has just come up with a brand-new product that can do it all. So, instead of having 3, 4 or maybe 5 different measuring instruments with you on inspection, you can now just settle with a single instrument, and the screen on which the results is displayed is made up of your phone or tablet.

PosiTector SmartLink consists of a transmitter on which you can connect all types of PosiTector probes. All measurements are uploaded, via the transmitter, to your mobile phone or tablet, and is added directly into the report you are about to make.

PosiTector SmartLink comes complete with free PosiTector App, AAA battery, protective rubber holster, belt clip, wrist strap, instructions, two years warrenty. Probes are purchased seperately.

PosiTest PC
This piece of news from DeFelsko measures uncured powder coatings using non-contact ultrasonic technology. This gage is able to predict the cured pwder coating thickness.

Probe Extender
Is a telescopic stick to use when measuring on surfaces which are beyond your normal range and you can also measure below floor level without having to succumb or kneel.


Our salespeople are ready with new knowledge

We constantly become smarter and smarter
A few months ago, Clemco Denmark's sales men were attending an intensive course at DeFelsko in the US. During the 3-day course, they went through all details – even the tiniest ones, and experiences were exchanged across the table. We now have the opportunity - and proof of it - that we must verify all DeFelsko's inspection devices. If your measuring gage needs a check or a service, then call our sales staff. You will find the numbers of Niels and Morten here on this page.

We have filled up a suitcase with the most common measuring equipment, the latest models, and their accessories, and we would love to come visiting you to demonstrate the contents of our inspection gear.
