When is a visual inspection done on a weld?

A visual inspection is performed before, during, and after the welding process to ensure the integrity and quality of the weld. Conducting a visual inspection before welding allows the inspector to examine the base materials and make sure they are clean, free from defects, and properly aligned. This step is crucial as it sets the foundation for a successful weld.

During the welding process, visual inspections help monitor the quality of the weld as it is being made. Inspecting the weld as it is formed allows for immediate feedback and correction of any issues that may arise, such as improper technique or problems with heat input.

Finally, inspecting the weld after it has cooled ensures that it meets the required standards for strength and appearance. This final inspection can identify any defects, such as cracks or incomplete penetration, which could compromise the weld's effectiveness and safety.

Performing inspections at all three stages—before, during, and after welding—ensures comprehensive quality control and helps guarantee that the welding meets industry standards and regulations.
