Webb6 apr. 2024 · Explanation: 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 in right place. Arc blow is mainly encountered during DC arc with straight polarity ... http://article.sapub.org/10.5923.j.mechanics.20120246.03.html
