Can modifications to welding procedures be made without approval according to AWS D1.1?

Modifications to welding procedures require review and approval to ensure that the integrity and quality of the weld meet the standards set by AWS D1.1. This requirement is in place to maintain consistent welding practices, uphold safety standards, and guarantee that structural integrity is not compromised. Changes to welding procedures can affect various aspects such as joint design, base material properties, or welding parameters, which in turn could impact the performance and durability of the welded structure.

By mandating that any changes undergo a formal review and approval process, AWS D1.1 helps ensure that modifications are thoroughly evaluated against established criteria and that they meet the architectural and engineering requirements. This process safeguards against unintended consequences that could arise from unapproved changes, including the introduction of defects or weaknesses in the welds.

While certain choices suggest that experienced welders or minor changes might not require approval, this approach can undermine the standardized practices essential for maintaining safe and reliable structural construction. Therefore, the correct course of action is to always seek review and approval for any modifications to welding procedures.
