What should the main manufacturer do after finding a defect in subcontracted welding?
Identify joints, materials, procedures, personnel and inspection records. Outsourcing does not remove your acceptance responsibility. Investigate causes and effects on similar work and plan suitable repair and reinspection. The subcontractor's certificate alone does not justify accepting defective work.
Can an organisation establish scope if welding is outsourced?
Define technical conditions, supplier competence, inspection and acceptance responsibilities. Identify activities actually managed and assumed within the assessed scope. Supplier certification can help but must represent the work and its boundaries. Do not present uncontrolled outsourced work as your own demonstrated production competence.
