Perfect welding in the spotlight
There is welding and... welding. Look closely at the welds in the attached photo: perfect work, isn’t it? Whether the process used is manual welding as shown in this photo, or submerged arc welding, plasma keyhole welding, automatic or semi-automatic welding – to name but a few – not only do our welds always look impeccable; various NDT testing methods such as RX, MT, and more, also confirm it.
How come Deprest’s welding is of such high quality?

Obviously, skilled people and state-of-the-art machinery are the beating heart of a company, and, fortunately, Deprest has both.
Yet, the many PQRs accumulated by Deprest over the years are another asset that shouldn't be underestimated in our sector.
(W)PQR stands for (Welding) Procedure Qualification Record and is a standardised procedure for welding certain materials, positions and thicknesses as a certified workshop. Welding Procedure Specifications (WPS) are supported by the PQRs.
The approval of a PQR is done by and under the supervision of an external inspection body and can quickly reach a cost of 3,500 euros or more per qualification, not including the company's own costs (such as joint preparation and welding time). Considering that, as a workshop, Deprest has over 100 PQRs, you do the math...
