What can excessive weaving in a weld lead to?

Excessive weaving in a weld can lead to an increased risk of defects. This technique, while sometimes used intentionally for specific weld profiles, can cause various weld issues when overdone. Weaving too much can result in improper heat distribution across the weld pool, potentially leading to defects such as undercutting, incomplete fusion, or excessive slag inclusions. Moreover, the inconsistent thermal cycles can produce residual stress or distortions in the welded joint, further compromising the integrity of the weld. Thus, maintaining a balanced technique is crucial for creating strong and reliable welds without introducing unnecessary risks.
