Abstract
The present invention provides a method and apparatus to control and verify weld-quality in a homopolar pulsed weld by measuring in-process parameters. Methods are disclosed for real-time weld-quality control in a weld-quality control system for homopolar pulsed welding, including measuring at least one in-process parameters that correlates to a resulting weld-quality of a weld. Further, methods are disclosed for post-process weld-quality verification for homopolar pulsed welding, including identifying at least one in-process parameter that may be used as a post-process weld-quality verification parameter and utilizing such a post-process weld-quality verification parameter to verify the weld-quality after a homopolar pulsed welding process.
