- providing a plurality of welding parameters for a manual welding operation;
providing a workpiece to be welded by the manual welding operation;
providing a calibration tool, the calibration tool including a plurality of first point markers;
providing a welding tool, the welding tool including a plurality of second point markers arranged in a predetermined pattern;
placing the workpiece on a weld platform;
placing the calibration tool on the weld platform;
capturing at least one image of the first point markers of the calibration tool on the weld platform;
processing the at least one image of the first point markers on the calibration tool to determine a position and orientation of an operational path for the manual welding operation based on at least one of the welding parameters;
manually welding the workpiece with the welding tool;
capturing a plurality of images of the second point markers on the welding tool during the manual welding operation;
processing the plurality of images of the second point markers on the welding tool to determine a position and orientation of the welding tool; and
determining a plurality of characteristics of the manual welding operation based on the position and orientation of the operational path and the position and orientation of the welding tool,wherein the characteristics are selected from the group consisting of;
a welding tool work angle, a welding tool travel angle, a welding tool travel speed, a bead placement, and a welding tool standoff distance.

Abstract
A system for characterizing manual welding exercises and providing valuable training to welders that includes components for generating, capturing, and processing data. The data generating component further includes a fixture, workpiece, at least one calibration devices each having at least two point markers integral therewith, and a welding tool. The data capturing component further includes an imaging system for capturing images of the point markers and the data processing component is operative to receive information from the data capturing component and perform various position and orientation calculations.
