WebMar 4, 2024 · The main reason for the undercut is that the heat of the arc is too high, that is, the current is too high. The incorrect angle between electrode and workpiece, unreasonable oscillation, long arc, unreasonable welding sequence, etc. will result in an undercut. Magnetic polarization of the arc during DC welding is also a cause of undercut. WebWelding slag inclusions can affect the quality of welds produced with flux-cored processes and occur when the slag becomes trapped in the weld when it solidifies. There are several best practices and techniques to help minimize this risk.
