A laser diode beam detector system has been devised to detect the position of groove axis and to discern the groove geometry. The signals from this sensor are fed into an automated control system incorporating micro-computer storing the expressions which calculate correct welding parameters for deviating weld groove. And relating the input from monitoring sensor, the control system gives commands for automated operations to the welding unit.
A prototype machine has been utilized for actual welding work, and has proved to ensure weldments requiring no remedial operation.
