ISO 14731 defines “Welding is a special process, which requires the coordination of welding operations to establish confidence in welding fabrication and reliable performance in service. The tasks and responsibilities of personnel involved in welding-related activities (e. g. planning, executing, supervising, and inspection) should be clearly defined.”
The standard defines further: Where welding coordination is carried out by more than one person, the tasks and responsibilities shall be allocated, such that responsibility is clearly defined and the persons are qualified for each specific welding coordination task.
Welding coordination is the sole responsibility of the manufacturer.
The manufacturer shall appoint at least one responsible welding coordinator.
Welding coordination may be subcontracted. However, compliance to this International Standard remains the responsibility of the manufacturer.
For all tasks assigned, welding coordinators shall be able to demonstrate adequate technical knowledge to ensure satisfactory performance of these tasks.
Personnel with comprehensive technical knowledge “Level A”
Full technical knowledge is required for the planning, executing, supervising and testing of all tasks and responsibilities in welding fabrication
Personnel with specific technical knowledge “Level B”
The level of technical knowledge needs to be sufficient for the planning, executing, supervising and testing of the tasks and responsibilities in welding fabrication within a selective or limited technical field
Personnel with basic technical knowledge “Level C”
The level of technical knowledge needs to be sufficient for the planning, executing, supervising and testing of the tasks and responsibilities within a limited technical field, involving only simple welded constructions.
