What is Understanding Arc Blow in Welding about?

This document discusses arc blow, which is the unwanted deflection of an electric arc during welding. There are two main types: magnetic and thermal. Magnetic arc blow occurs due to the magnetic field created around the arc and workpiece by the welding current, which can deflect the arc. Alternating current helps counteract this effect through induced eddy currents. Some techniques for preventing excessive magnetic arc blow include keeping the arc short, reducing current, angling the electrode, and applying
