What can the distortion of the electromagnetic field lead to during welding?

The distortion of the electromagnetic field during welding can indeed lead to electrode misalignment. In the process of Shielded Metal Arc Welding (SMAW), the electromagnetic field is generated by the electric current passing through the electrode and the workpiece. If this field is distorted, it can affect the position and movement of the electrode.

When the electromagnetic field does not function optimally, it may not effectively guide the electrode or maintain its intended path. This misalignment can result in an improper angle or distance from the workpiece, leading to poor weld quality, increased porosity, and incomplete fusion. Proper arc length and stability are crucial for achieving strong, defect-free welds, and any disruption in the electromagnetic field can significantly affect these factors. Therefore, understanding the impact of electromagnetic distortion is vital for weld quality and precision.
