System and method for calibrating a welding trainer

Abstract

A system and method for calibrating a welding training apparatus. The system includes reference markers disposed in a 3-D space of a welding environment so as to have a known fixed orientation in the 3-D space of the welding environment. An image capturing device scans the welding environment, which includes a welding coupon or a workpiece. The image capturing device also captures an image of the welding environment. An object recognition device automatically identifies the welding coupon or the workpiece in the captured image and automatically associates a weld path to the identified welding coupon or workpiece. A calibration device automatically calibrates the welding training apparatus by correlating the weld path to the 3-D space of the welding environment based on the reference markers.

AI Technical Summary

Benefits of technology

This patent is about a system and process for training welders by using reference markers in a 3-D space. A calibration device automatically adjusts the training equipment based on the markers. This helps ensure that the training is accurate and efficient.

Problems solved by technology

This would require the welder to direct their field of vision away from the welding work area and as such was undesirable.

In addition, in many cases, the welding machine may not be located close to the work space.

However, before the process can be set up, the welder may need to see the display readouts that are physically located on the machine.

However, monitors consisting only of audio arc parameter indicators are hard to hear and interpolate and are not capable of achieving the desired closeness of control and quality of weld often required.

In addition, related art welding devices have limited guidance with respect to aiding the welder, whether a beginner or exercised, as the weld is being performed.
