What does AWS D1.1 guideline say about repair welding?

The guideline outlined in AWS D1.1 regarding repair welding emphasizes the necessity of adherence to approved welding procedures and the involvement of qualified personnel. This requirement ensures that any repair work meets the necessary safety and structural integrity standards defined by the code. Repair welding can involve critical elements of a structure, meaning that deviations from established procedures or involvement of unqualified personnel could lead to compromised safety or performance of the welded joints.

In essence, having approved procedures ensures consistency and quality in the repair process, while qualified personnel possess the skills and knowledge to execute these repairs correctly. This approach mitigates risks associated with improper welding practices, ultimately upholding the integrity of the structure being repaired. It reflects the code's commitment to safety and adherence to engineering standards in construction and structural applications.
