Arc Oscillation

The mechanical or electromagnetic transverse movement of the arc across the joint width purposefully influences heat input and weld pool geometry. This improves sidewall fusion and minimizes porosity.

When weaving, guide the torch evenly across the joint. This distributes the heat better and gives you a clean bond to both edges. If you weave too wide or too erratically, the pool gets too big and the weld runs away on you or you burn the structure. Keep the motion calm and steady, then the weld will be clean and tight.
