Solutions to Undercut Defects

The primary solution to undercut defects is to properly control the welding current, which can largely avoid the occurrence of undercut defects. By maintaining a stable arc length and uniform welding speed through controlled welding current, the undercut phenomenon caused by unstable welding speed can be avoided. During the adjustment of welding parameters, it is crucial to carefully verify the parameters and ensure that the tilt angle of the welding electrode matches the travel speed, which may improve welding quality. Additionally, attention should be paid to inspecting the weld seam and promptly addressing any issues found.
