Responsible Welding Service (RWC)

Responsible Welding Service (RWC)

Responsible Welding Services 

ANDT Responsible Welding Services (RWC) to help you comply with the regulation of CE (Conformité Européene) marking for structural steel.

CE (Conformité Européene) marking has become necessary for products sold in the EU construction market in July 2014. Under this regulation, all companies that manufacture steel to be sold in the EU for construction are required to have documented welding quality management and will need to have in house RWC or have access to one.

RWC's responsibility is to control and supervise all welding activities, and to ensure that all steel structures meet the satisfactory levels of mechanical resistance, serviceability, and durability.
BS EN 1090-2 identifies four classes for structural steel and they are based on the intended use of the structure and criticality. The higher the execution class, the more extensive quality criteria are implemented. Companies that use EXC 2, 3, and 4 welding activities require an RWC.
Execution class  and type of work undertaken:

  • EXC 1 - Agricultural buildings
  • EXC 2 - Buildings
  • EXC 3 - Bridges
  • EXC 4 - Special structures

Many organizations may not require a full-time RWC and can potentially benefit from our RWC services.
ANDT can supply the services of an RWC to oversee and control your welding activities.
RWC will look at:

  • Proofread contracts.
  • Tender launches and catches the requirements of contracts.
  • Materials verification
  • Non-destructive testing of welds
  • Ensure procedures and are suitably qualified

With our RWC services, our clients can be ensured that your structured steel complies with CE marking regulation.
