1. A weld training system, comprising:
a display;
a camera;
a processor coupled to the display and the camera; and
a welding helmet comprising a view port and configured to hold the camera and the display such that, when the welding helmet is worn by a wearer, the display is viewable by the wearer through the view port, the processor configured to control the display to display, to the wearer, simulated welding images based on images taken by the camera, a simulated object generated based on information received from the camera, and a graphic based on performance of a simulated weld detected using the camera;
wherein the display, the camera, and the processor are in a same device detachably attached to the welding helmet.
