Bilfinger UK is recruiting an experienced Welding Supervisor to lead and control all site welding activities on the mechanical and piping installation scope at the Highview Power Liquid Air Energy Storage project at Carrington – the UK’s first commercial plant of its kind.
Reporting to the Mechanical / Piping Superintendent, the role will supervise day‑to‑day welding workforce, ensuring compliance with approved Welding Procedure Specifications (WPS) and applicable standards (ASME B31.3, BS EN 13480, BS EN 1090, ASME IX, PED). The candidate will work closely with QA/QC, Piping/Mechanical Superintendents and the NDT subcontractor to deliver right‑first‑time welds and a clean inspection and test record.
Key Responsibilities
* Supervise and coordinate the daily activities of the site welding workforce (welders and pipefitters), allocating labour to the work fronts in line with the construction programme.
* Ensure all welding is carried out strictly to approved WPS, and that welders hold current, position‑ and process‑relevant qualifications (ASME IX / BS EN ISO 9606) before work commences.
* Maintain the welder qualification register, weld map / weld register and consumable control records, ensuring full traceability of materials and consumables.
* Control welding consumables – issue, storage, baking and handling – particularly low‑hydrogen and specialist consumables for cryogenic and alloy materials.
* Manage preheat, interpass temperature and any required post‑weld heat treatment (PWHT) in accordance with the WPS.
* Carry out and document weld fit‑up and pre‑weld checks, and present completed welds to QA/QC and the NDT subcontractor for inspection.
* Liaise with QA/QC Inspectors and third‑party / NOBO inspectors on weld audits, NDT results and the close‑out of repairs and NCRs.
* Monitor weld quality and repair/rejection rates, identify trends and take corrective action with the welding team to drive down defects.
* Ensure all welding activities are carried out safely – hot work permits, fire watch, fume extraction, confined space and working‑at‑height controls – in line with the project HSEQ plan and CDM 2015.
* Read and interpret isometrics, GAs, P&IDs and welding documentation to confirm joints are welded as designed.
* Support material control, spool receipt and the management of site/tie‑in welds where spools are free‑issued.
* Attend daily coordination meetings and report welding progress, manpower and constraints to the Superintendent.
Qualifications
* Proven experience as a Welding Supervisor on large‑scale mechanical / piping construction projects.
* Recognised welding qualification – CSWIP 3.1 Welding Inspector, or IWS / EWS (International / European Welding Specialist), or time‑served senior welding background with supervisory experience.
* Strong working knowledge of ASME B31.3, BS EN 13480, BS EN 1090 and ASME IX, and the ability to read and apply WPS / PQR.
* Sound understanding of welder qualification, consumable control, preheat/interpass control and weld traceability.
* Ability to read and interpret isometrics, GAs, P&IDs and welding / NDT documentation.
* SMSTS or SSSTS (or willingness to obtain), with a strong, demonstrable commitment to site safety and hot‑work controls.
* CCNSG Safety Passport.
* Result oriented, with a ‘right first time’ mentality – focused on weld quality, low repair rates and a clean inspection record accepted by QA/QC and the client.
