28.6. What are the solutions to edge biting defects?

The main solution to edge biting defects is to properly control the welding current, which can largely prevent the occurrence of edge biting defects. By controlling the welding current, keeping the arc length stable, and maintaining a uniform welding speed, the edge biting phenomenon caused by unstable welding speed can be avoided. During the adjustment of welding parameters, it is also important to carefully verify the parameters; the inclination angle of the welding rod should match the travel speed to potentially improve welding quality. At the same time, it is necessary to check the weld condition and address any issues found in a timely manner.
