The standard covering fabricated structural steelwork is BS EN 1090: Execution of steel structures and aluminum structures.
Since July 2014 is has been a legal requirement for all fabricated structural steelwork put on the market to be CE Marked.
This marking is categorised in two parts: Part 1 of the standard is the Requirements for Conformity Assessment of Structural Components. It describes how manufacturers can demonstrate that the components they produce meet the declared performance characteristics (the geometric and structural characteristics).
Part 2 is the Technical Requirements for Steel Structures. It specifies the requirements for the execution of steel structures to ensure adequate levels of mechanical resistance and stability, serviceability, and durability. It determines the performance characteristics for components that the manufacturer must achieve and declare through the requirements of Part 1.
Steelwork contractor requirements for CE Marking
In order to be able to CE Mark the fabricated structural steelwork produced by steelwork contractors, they are required to declare performance to the System 2+ level of assessment. This requires them to undertake:
Initial type-testing of the product Factory Production Control (FPC), which will include:
- Implementation of FPC system procedures
- Appointment of a responsible welding coordinator (RWC)
- Implementation of welding quality management system (WQMS) procedures
- Further testing of samples taken at the factory in accordance with the prescribed test plan
The structures must also be assessed by a notified body that will carry out:
- Initial inspection of the manufacturing plant
- Initial inspection of the FPC
Continuous surveillance, assessment and approval of the FPC, which will typically include:
- An annual audit to ensure continued competence to the declared Execution Class (Table B.3 of BS EN 1090-1 sets out minimum levels for the routine surveillance intervals)
- The notified body will then issue a FPC Certificate and Welding Certificate identifying the Execution Class that the steelwork contractor has achieved.
Do your welders need CE Marking?
Yes if you are fabricating structural components for use within the EU. For structural steel fabrication, all engineers, main contractors and steelwork contractors need to ensure that every component used for a project complies with the requirements of BS EN 1090-1 (execution of steel structures and aluminum structures).
Can ITCL supply welding co-ordinators?
ITCL can help your company through part or the entire process regarding CE Marking as we have qualified welding coordinators and certified welding inspectors, together with our Non-destructive Testing (NDT) inspection services.
The responsibilities and duties of a welding co-ordinator include:
- Understanding and application of code and standard requirements
- Parent material verification, control and traceability
- Welding consumables identity - verification against documentation, and correctness of welding consumables (electrodes, filler wires, consumable inserts, gases, fluxes etc)
- Post-weld visual inspection - visual inspection and dimensional check of completed weldment against specification requirements and drawings
- Welding procedures - establishing that a procedure is available, has been approved as required by the appropriate authority and covers the scope of materials used in production
- Review of welder qualification tests - review of test pieces and destructive tests, and verifying compliance with appropriate standards and specifications
- Verification that all valid welder approvals are available, and cover the scope of materials used in production.
- Verification that post weld heat treatment has been conducted in accordance with specification requirements
- Non-destructive testing (NDT) reports - assessment of NDT reports on welding, or fabrication work, for which a Welding Inspector may be/is typically responsible
- Preparation, review, maintenance and archiving of comprehensive inspection reports
- Interpretation of weld drawings and weld symbols
- Appreciation of the factors influencing the formation of weld defects and their acceptability in relation to the written specification
- Verification of NDT reports on welding work for which the Senior Welding Inspector is responsible. (This may include radiographic interpretation)
- Ensuring that the required quality assurance standards and procedures are maintained
- Understanding of the Pressure Equipment Regulations and Pressure Equipment Directive
- Understanding of conducting hardness, ferrite and pressure testing.
- Certification of compliance - final acceptance and certification that all quality related requirements of the specification have been met.
