Undercut
Undercut and is that part of the groove as end or both ends of the weld bead. As a common cause, TIG welding, excessive current, or the lack of bar pressure. The semi-automatic welding voltage is too high, under-current. Arc welding and coating is excessive current. Other bars occur by chance or unstable conditions for the angle of the welding torch.
