Dross adherence

The undesirable adhesion of solidified metal droplets to the lower edge of the kerf, caused by incomplete melt expulsion. This typically necessitates labor-intensive post-processing.

Melt drops stick to the cut edge if the melt is not blown out cleanly. This usually happens when the parameters are wrong, the nozzle is too far away, or the gas flow isn't right. The stuck drops disturb the seam formation and can later lead to lack of fusion. If you see this, you have to grind off the deposits and rework the spot. Adjust the settings before continuing to weld, then you won't have this problem.
