Weld training simulations using mobile devices, modular workpieces, and simulated welding equipment

A weld training system, comprising:

• a mobile electronic device configured to conduct a weld training simulation, the mobile electronic device comprising:
• a display screen,
• processing circuitry, and
• memory circuitry comprising computer readable instructions which, when executed by the processing circuitry, cause the processing circuitry to:
• display, on the display screen, a plurality of selectable settings of the weld training simulation,
• receive one or more selections of the plurality of selectable settings of the weld training simulation, and
• display, on the display screen, a rendering based on the one or more selections, the rendering comprising a preview of the weld training simulation if the weld training simulation were conducted with the one or more selections.
