Solutions to Undercut Defects

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