Methods and apparatus for weld training are provided. An example weld training system includes a display device, an input device, a processor, and a machine readable storage device storing machine readable instructions. The instructions may be executed by the processor to: enable the user to design a weld procedure by selecting weld parameters; enable the user to simulate setting up a simulated physical welding environment; simulate a welding operation on a simulated workpiece using the selected weld parameters in a welding model and a setup of the simulated physical welding environment to determine a modeled result of the welding operation; display a simulation animation of the welding operation on the display device according to the simulation; and display the modeled result on the display device using at least one of an image of a surface of a weld bead or a cross-section of the weld bead and the workpiece.
