Welding Coordination: Roles, Responsibilities and Interfaces
The coordination function
Welding coordination covers the organisational and technical arrangements needed for welding production to meet requirements. It includes planning, scheduling, assigning qualified personnel, controlling subcontractors, managing consumables and equipment, and ensuring inspection and records are in place. The coordinator is a management function, not a substitute inspector: the role is to ensure the right arrangements exist, not to sign off every weld personally.
Concepts a candidate must know
Understand the difference between responsibility and delegation. Tasks may be delegated to suitably competent people, but accountability for coordination remains with the designated coordinator. Know that coordination requirements scale with the complexity of the product, the materials and the level of quality risk - a simple carbon steel structure needs less coordination than a pressure-retaining assembly in creep-resisting steel.
Be clear on interfaces: design, purchasing, production, inspection and the client. Coordination includes verifying that subcontractors work to the same procedures and qualification standards, and that purchased consumables arrive with valid certification.
Traps
Questions often present a coordinator who personally performs all inspection or personally welds to "save time." That is a conflict of duties and normally the wrong answer. Another trap is treating a coordination certificate as a licence to weld, or assuming delegation removes responsibility.
Worked example
A subcontractor is engaged to weld part of a pressure vessel. The coordinator's duty is to check the subcontractor's WPS, PQR and welder qualifications are valid for the joint and material, agree the inspection plan, and ensure records flow back. Rule of thumb: for any interface, ask three questions - who is qualified, against which procedure, and where is the record kept?
Practical anchor
Maintain a coordination plan listing each task, the responsible person, the competence evidence and the record produced. This single document answers most scenario questions.
