What should be done if holes and projecting globules are found in a weld?

When holes and projecting globules are found in a weld, the ideal course of action is to remove all the old weld and reweld the joint. This approach addresses the underlying issues causing these defects, which can stem from various factors such as improper welding parameters, contamination, or inadequate penetration.

Simply leaving the weld as is or conducting just a visual inspection does not resolve the problem, as these defects may compromise the structural integrity of the weld and lead to failure during service. Covering the weld with a protective coating may shield it from external factors but does nothing to rectify the inherent flaws in the weld itself.

By completely removing the defective weld, the welder ensures that they are starting with a clean slate, allowing for proper re-examination of the joint preparation and welding technique. Re-welding the joint under optimal conditions contributes to achieving a sound and reliable weld, essential for safety and performance in any structural application.
