D. Hughes Welding & Fabrication was founded as a mobile welding and fabrication service in 1984 by Dewi Hughes.

As the business grew he established a small workshop and continued in general welding but also began to specialise in structural steelwork and pipework. The business quickly expanded and soon began to undertake pipeline projects and ship repairs as well as general fabricating and welding.

In 1990 the company moved to a purpose built 11,000 sq. ft. premises on the Gaerwen Industrial Estate, Anglesey, which was adaquate to accommodate the majority of large scale projects including the building of modules for ship repairs, prior to transporting to any designated dry dock.

Today the company continues to evolve its welding procedures and personnel, with current qualifications including DNV-GL certified welding personnel and procedures to the latest international standards (BSENISO 15614-1:2004 + A2 2012 and BSENISO 9606-1:2013 on Carbon Steel & 9606-2:2004 on Aluminum also to AP1.1104 and BS 4515-1:2009 on Pipe Lines.

Recent projects have seen an investment in semi-automatic tracked welding equipment to facilitate some 2km of overhead fillet welding and down hand full penetration butt welds on a bridge deck. These kits were expertly supported by Gulco and were instrumental in the delivery of the project timeline.


We have a diverse range of clients both locally and internationally. These vary from domestic contracts requiring Execution Class 2 CE Marked steel on railings, structural steel building, portal frame etc. and upto class 4 for bridges, petrochemical and the nuclear industry and shipping operators.

To continue to be successful in our chosen markets, we have had to constantly evolve our CAD and 3D modelling capabilities as well as maintaining a suite of Quality and production welding Qualifications, including ISO 9001:2015 and BSENISO 1090-2:2009+A1:2011.

CE Marking

D Hughes Welding and Fabrication are certified to Execution Class 4 of the CE marking regulations under EN1090-1, and have been so since the legislation was introduced in July 2014. This is the highest execution class under the regulations, and requires us to have access to an International Welding Engineer in the case of Execution Class 3 and 4 projects.

CE Marking is British and European Law requiring all structural steelwork to be manufactured only by qualified parties, and supplied with certification thereunder.

It was actually introduced under the Construction Products Regulations (CPR), which not only place duties with the manufacturer, but also with the client or principal contractor, who must ensure, amongst other duties, that the correct execution class is specified at the outset of the project.

The implementation of the CE marking system is now overseen by your local building control department.
