Welding process, welding system, and welded article

A welding process, comprising:

• generating an arc energy from an arc welder and a laser energy from a laser;
• directing the arc energy toward an article and directing the laser energy to rotate along a rotation path on the article to form a common molten pool on the article;
• and
• directing the arc energy and the laser energy toward the common molten pool to generate a centrifugal force on the common molten pool to increase a contact angle between the article and the molten pool such that a weld formed from the common molten pool has a root reinforcement devoid of features extending beyond a distance beyond coplanar with a distal surface of the article of 0.065 inches.

A welding process, comprising:

• generating an arc energy from an arc welder and a laser energy from a laser;
• directing the arc energy toward an article and directing the laser energy to rotate along a rotation path on the article to form a common molten pool on the article and to fully penetrate the article and form a keyhole surrounded by the common molten pool;
• and
• directing the arc energy and the laser energy toward the common molten pool to cause the keyhole to rotate such that a distal surface of the article including a weld formed from the common molten pool is devoid of turbulent features.
