Systems and methods to provide weld training

A weld training device, comprising:

• a display device;
• an input device;
• a processor;
• and
• a machine readable storage device comprising machine readable instructions which, when executed by the processor, cause the processor to demonstrate to a user an effect of a combination of welding-related variables by:
• enabling the user to design a weld procedure using the input device by selecting weld parameters including weld current and weld voltage;
• enabling the user to select a welding power supply model;
• simulating a welding operation on a simulated workpiece based on the selection of the welding power supply model, using the selected weld parameters in a welding model and a simulated physical welding environment to determine a modeled result of the welding operation
• displaying the modeled result of the weld 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 simulated workpiece;
• and
• displaying information about an anomaly present in the weld determined based on the simulation, the information about the anomaly comprising at least one of a cause of the anomaly, a suggested change in one or more of the welding-related variables to avoid the anomaly, or a location of the anomaly in the image of the weld bead or in the cross-section of the weld bead.
