When should welding inspection be performed?

Welding inspection is crucial at multiple stages of the welding process to ensure quality and safety. Performing inspections before welding starts allows for the verification of materials, equipment, and readiness of the welder, which is essential for ensuring that all preparations meet the required standards and specifications.

During welding, inspections are vital for monitoring the process itself, checking parameters like temperature, technique, and overall execution to detect any issues as they arise. This can prevent defects that might not be visible until after the welding is completed.

After weld completion, inspections are necessary to assess the final product for flaws, such as cracks or incomplete fusion, that could compromise the integrity of the weld. Inspecting at this stage ensures that the weld meets all necessary codes and standards for performance and safety.

Therefore, conducting inspections at all three stages—before, during, and after welding—provides a comprehensive approach to maintaining quality control throughout the welding process. This multifaceted inspection strategy maximizes the likelihood of identifying and rectifying potential issues, ensuring that the final weld is both structurally sound and meets the required specifications.
