The weld pool contains abundant information about the welding process. Its observation can generate data for studying the welding process. Its control could provide an entirely new method to reach the desired weld quality. A real-time sensing technique has been developed to sense the 2D shape and 3D surface of the weld pool. Thus, abundant data can be acquired from the weld pool and used to correlate the pool geometrical appearance with the weld penetration. The weld pool is characterized using a few parameters. The desired weld pool can be acquired by controlling these parameters. Currently, experiments are being conducted to achieve a precise control of the 2D weld pool shape. Experiments for controlling the pool area have been completed.
