Does the angle of the electrode control arc blow?

The concept of arc blow in Shielded Metal Arc Welding (SMAW) relates primarily to the behavior of the electric arc in the presence of magnetic fields, typically caused by the current flowing through nearby conductive materials or by the weld itself. The angle of the electrode does influence the direction and stability of the arc; however, it is not a primary factor in controlling arc blow.

While the electrode angle can impact how effectively the electrode transfers heat to the workpiece and can alter the deposition characteristics of the weld, arc blow is fundamentally caused by external factors, such as magnetic fields created by stray currents or other magnetic influences in the welding environment. These fields can deflect the arc away from the intended path, regardless of how the electrode is angled.

Therefore, stating that the angle of the electrode does not control arc blow accurately reflects the dynamics involved in welding. The behavior of the welding arc is predominantly determined by external magnetic influences rather than the positioning of the electrode itself.
