Right Answer is:
Arc blow
SOLUTION
- In electric arc welding, the deflection of the arc from the weld point is called Arc blow.
- Arc blow is basically a deflection of a welding arc from its intended path i.e. the axis of the electrode.
- Deflection of the arc during welding reduces the control over the handling of molten metal by making it difficult to apply the molten metal at right place.
- Arc blow is mainly encountered during DC arc with straight polarity welding due to an interaction between different electromagnetic fields in and around the welding arc.
