ABSTRACT:
Welding using a laser, which leaves keyhole portions at each pass, that allow gases to vent. That keyhole portion is an area within the interior portion, e.g., an inside of a spiral or a circular arc. The keyhole is not processed by the laser and gases can escape. The laser later circles back to process the area.
