Metalworking and welding
Fabrication shops, machine shops and steel structure manufacturers — without ISO 3834 and EN 1090 there is no serious structural work, either at home or in the EU.
Standards in this industry: metalworking and welding
A welded joint is the only part of a product that cannot be checked with the naked eye. That is why ISO 3834 does not ask you to weld better, but to prove how you weld: procedure specifications (WPS) backed by qualification (WPQR), certified welders to EN ISO 9606, an appointed welding coordinator to EN ISO 14731, control of base and filler materials and weld inspection records. The standard has three levels — comprehensive (part 2), standard (part 3) and elementary requirements (part 4) — so you choose according to what you actually do.
EN 1090 is what turns all of that into a market document: load-bearing steel and aluminium structures carry CE marking, and to apply it you need factory production control and a certificate from a notified body. The execution class (EXC1 to EXC4) is determined by the structure, and from EXC2 upwards ISO 3834 is also required — which is why the two standards usually go together. The rest is a plant like any other: ISO 9001 for planning, purchasing and complaints, ISO 45001 for cranes, burns and welding fumes, ISO 14001 for metal waste, emulsions and degreasing agents.

How we can help
WPS, WPQR, welder certificates and coordinator appointment — put together to stand up to an audit, not to sit in a binder.
EN 1090 factory production control and preparation for notified body surveillance, with a clear execution class.
ISO 9001 and ISO 3834 are frequent requirements in tender documentation for structural steelwork.
ISO 45001 for work at height, cranes, fumes and sparks — with training that makes sense to the person at the machine.
