Welding Consumables: Ensure that the welding consumable are suitable for the process and stored in a controlled environment e.g temperature, humidity. Non-Destructive Testing (NDT): Oversee the NDT (Visual, MPI and UT) and ensure that these tests meet the required acceptance criteria as per SCEW 1800. This includes reviewing and certifying the results of NDT methods performed on welds. Progress Reporting: Provide weekly progress reports on the status of inspections, findings and corrective actions needed for non-compliant work. Onsite Welding Inspections: Field Inspection: Inspect all field welds during the onsite assembly of the steel components at the project locations (Duddeston Junction Viaduct, Curzon 2, Saltley Canal Under Bridge, Lawley Middleway and Curzon 3 Tripods. Ensure that welding operations adhere to approved WPS and project standards. Weld Monitoring: Conduct inspection and verification of joint preparation, welding parameters, intermediate passes and final weld visual inspection. Non-Destructive Testing (NDT): Oversee the NDT (Visual, MPI and UT) and ensure that these tests meet the required acceptance criteria as per SCEW 1800. This includes reviewing and certifying the results of NDT methods performed on welds.
