Understanding Acceptable Welding Undercut and Its Acceptance Criteria Welding undercut is a groove melted into the base metal adjacent to the weld toe that isn’t filled with weld metal. While some degree of undercut may seem minor, excessive or poorly formed undercut can reduce fatigue life, create stress risers, and …
