Weld training systems to synchronize weld data for presentation

A weld training system, comprising:

• a display device;
• a processor;
• and
• a machine readable storage device comprising machine readable instructions which, when executed, cause the processor to:
• collect, from welding-type equipment during a welding-type operation, data describing the welding-type operation;
• collect, from a set of one or more cameras, images depicting one or more of:
• a) a posture of an operator or a technique of the operator during the welding-type operation;
• or
• b) a welding torch used in the welding-type operation;
• synchronize the collected data and the collected images with comparative images of a predefined correct performance of the welding-type operation;
• and
• display the collected data and the collected images together in a synchronized manner on the display device such that the processor updates the display device to display corresponding synchronized data and images when a portion of the welding-type operation is selected for viewing, the displaying comprising displaying the collected data, the collected images, and the comparative images.
