Who we are...

We assist you to meet welding code, specification and contractual requirements

Welding is still referred to as a “special Process” in common ISO 9001 quality systems. This means that its quality cannot be readily verified. However to ensure this quality the welding Industry faces a lot of requirements. Besides contract requirements there are requirements in national, European and International laws, norms, codes and directives.

Well known are the Pressure Equipment Directive, ASME boiler code, EN-1090 series, ISO 3834 series. And of course many others but in general the core requirement in all these codes is the development and implementation of a fabrication control system.

To develop and implement such a quality or fabrication control system requires management, personnel, procedures and documents. And that is where De Lasserij, based upon over 30 years of experience in national and international projects, can support the welding industry in all aspects.
