After a weld repair and reinspection, the inspector should:

Filling out a second inspection report is the appropriate action after a weld repair and reinspection. This procedure ensures that there is a documented record of the inspection that specifically addresses the repairs made, which is essential for quality control and traceability in welding practices.

A second inspection report provides a clear, formal record that reflects the current status of the part following the repair. It maintains thorough documentation, which is crucial during audits or future inspections and can help validate that the repair was done to the required standards. This approach promotes accountability and ensures that all stakeholders have access to up-to-date information regarding the weld's integrity.

In contrast, crossing out a signature on the original report fails to provide clarity or proper documentation of the changes made after the repair. Simply marking the part or verbally informing the foreperson does not produce a tangible record and can lead to misunderstandings or miscommunication about the part's condition. Maintaining a rigorous documentation process is vital in welding and inspection, making the completion of a second report the most suitable choice.
