Systems and Methods to Control Welding Processes Using Weld Pool Attributes

Abstract:

Disclosed are systems and methods for controlling welding processes in real-time, or near real-time, as a function of a measured weld pool attribute. The welding-type system includes power conversion circuitry and control circuitry. The power conversion circuitry converts input power to welding-type power for use by a welding torch to form a weld pool. The control circuitry control one or more parameters of the welding-type system during a welding operation based on one or more attributes of the weld pool determined using a sensor configured to capture the one or more attributes of the weld pool. The one or more attributes may include, for example, a width of the weld pool and/or a depth of depression in weld pool.
