# Welding, inspection and QA/QC in Groningen > DEHAAS works in Groningen and around Groningen and Delfzijl: weld inspection, welding coordination, WPS and WPQR, EN 1090 and ISO 3834. Source: https://dehaasprojects.com/en/coverage/groningen-welding/ Updated on: 2026-11-04 DEHAAS works from Menaam in Friesland throughout the Netherlands, including Groningen. Groningen combines heavy process industry in the Eemsdelta with shipbuilding around Hoogezand and a strong energy sector. Chemicals, equipment manufacturing and the transition to hydrogen are the defining themes here. Groningen is about an hour's drive from Menaam, so site visits are easy to schedule. Much of the work needs no site visit at all: a procedure review, an assessment of welder qualifications or a question to the [Welding & Quality Assistant](/en/welding-assistant/) works perfectly well remotely. - Weld inspection and QA/QC on site - Welding coordinator to ISO 14731 on call - WPS, WPQR and EN 1090 support - Remote assessment without a site visit ## Industry in Groningen Groningen combines heavy process industry in the Eemsdelta with shipbuilding around Hoogezand and a strong energy sector. Chemicals, equipment manufacturing and the transition to hydrogen are the defining themes here. The working area within the province includes Groningen, Delfzijl, Veendam, Hoogezand and Winschoten. That industrial profile shapes the questions that arise here. Where a steel fabricator wrestles with execution classes and the FPC system, an equipment manufacturer deals with a notified body and a machine builder with distortion and dimensional stability. DEHAAS works for all three. ## Which standards matter most here In the Eemsdelta the PED applies, with EN 13480 for piping and ASME B31.3 in internationally based projects. In shipbuilding the classification society rules apply, and hydrogen projects add hardness and leak tightness requirements. Whichever standard governs, the question is always the same: can you demonstrate the welding complies. That calls for a procedure matched to the work, a qualification record covering the range, welders working inside their qualification and examination reported on time. See [all services](/en/services/). ## What an assignment looks like Much of the work here involves piping and equipment: writing welding plans, setting NDT extent per system class and supervision during a shutdown. We also assess existing procedures for suitability in hydrogen service. A typical route starts with a half hour conversation about what is at stake, followed by a review of the existing documents. That produces a concrete plan: which qualifications are needed, which documents are missing and in what order that is resolved. Execution follows after that. ## On site or remote Groningen is about an hour's drive from Menaam, so site visits are easy to schedule. Inspection during production, witnessing a test coupon or attending an audit requires presence; document review, procedure writing and advice do not. That combination keeps cost down: travel is limited to the moments where it genuinely adds something. See [remote WPS and PQR review](/en/services/remote-wps-pqr-review/) and [our approach](/en/our-approach/). ## Frequently asked questions ### Does DEHAAS travel to Groningen? Yes. Groningen is about an hour's drive from Menaam, so site visits are easy to schedule. For inspections, audits and witnessing test coupons we attend on site; document work and advice are handled remotely. ### What does a welding inspector on site cost? That depends on scope and duration. DEHAAS works per assignment with a proposal agreed in advance, so you know where you stand. Request a [quotation](/en/quote/) with a short description of the work. ### Can I have just my WPS reviewed? Yes, that is one of the most requested services. You send the procedure and the underlying qualification record, we assess whether the range is correct, whether the variables are right and whether the document is usable by the welder. See [remote WPS and PQR review](/en/services/remote-wps-pqr-review/). ### Does DEHAAS work outside the Netherlands? Yes, across Europe and on a project basis in North America. Reporting in Dutch or English.
