The WA CLEAN
Technology is an
electronic optical device using as its working principle the analytical
colorimetry to support the visual assessment of the surface preparation grades
of uncoated steel substrates as defined in ISO 8501-1 or in SSPC-VIS 1. In July
2019, the WA CLEAN Technology received official accreditation via the ISO/TR
WA CLEAN Technology
Adopted by the End Users
WA CLEAN Technology has been adopted in several
industrial fields and not only in surface preparation projects. The WA CLEAN
device has been developed in order to help our customers to implement the ISO
8501-1 standard. To avoid any misinterpretation, the goal of the device is not
to replace the ISO 8501-1, but to support the appropriate implementation.
The cornerstone of the customer benefits
provided by the WA CLEAN device is reinforcing the surface preparation grades
visual assessment done by using the ISO 8501-1 reference photographs. Due to
its analytical colorimetry working principle, the WA CLEAN device will measure
specific cleanliness indexes on the initially visually qualified blast-cleaning
grades. The usage of WA CLEAN device will allow to our customers to implement a
quality follow-up on their blasting process in terms of the cleanliness level
of their blasted parts.
The WA CLEAN Technology can be also used to
reduce extra blasting time, saving money and improving the quality level by
fending off the eventual over-blasting phenomenon that could affect other
important surface preparation parameters after the blasting process such as the
Some examples of industrial applications where
the WA CLEAN Technology is already employed are mentioned here:
• Steel pipes manufacturing for oil and gas
industry where the cleanliness level is one of the required parameters after
the blasting process and before the next stage of process, namely the epoxy
• Cast iron automotive parts in cast iron
foundries for the quality control of the desanding operations.
• Trailer manufacturing for the control of the
cleanliness level of the blasted parts prior to galvanization.
• Freight wagons for the control of the
cleanliness level of the blasted parts prior to coating applications.
• Cold-drawn bar producers for the optimization of their descaling operations.
A Step Ahead
We will see more and more examples of how our industry is migrating to Industry 4.0 and the digitalization of tools and instruments used in the manufacturing processes. And it’s what we are looking forward to at Winoa. Soon the WA CLEAN technology will be functional via a smartphone with the possibility to generate instant quality follow-up reports of your blasting process, everywhere and at any time with the WA CLEAN 2.0 version.
The WA Clean Tool Kit
This patented and ISO TR 22770-certified technology is the ideal way to evaluate and check the cleanliness of a blasted surface in accordance with international standards independent of any human interpretation. It reads, quantifies and archives the degree of surface cleanliness you have achieved while being very easy to use.
