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. ### Claim 2 (depends on 1) The weld training system as defined in claim 1, wherein the collected images are overlaid with the comparative images on the display device. ### Claim 3 (depends on 1) The weld training system as defined in claim 1, wherein the instructions are to cause the processor to process the collected data to generate a representation of the weld bead generated by the welding-type operation. ### Claim 4 (depends on 3) The weld training system as defined in claim 3, wherein the instructions cause the processor to display the collected data by displaying the representation of the weld bead generated by the welding-type operation. ### Claim 5 (depends on 1) The weld training system as defined in claim 1, wherein the corresponding synchronized portions of the data and the collected images represent a time period during which a specified portion of the welding-type operation occurred. ### Claim 6 (depends on 1) The weld training system as defined in claim 1, wherein the instructions further cause the processor to: collect weld torch position information during the welding-type operation; synchronize the weld torch position information to one or more of the data or the collected images; and after the welding-type operation, determine the position of the welding torch with respect to the weld bead to determine the portion of the welding-type operation to be displayed via the data or the collected images. ### Claim 7 (depends on 1) The weld training system as defined in claim 1, wherein the instructions further cause the processor to align and scale a representation of the data with the collected images on the display device. ### Claim 8 (depends on 1) The weld training system as defined in claim 1, wherein the instructions cause the processor to display the corresponding synchronized portions of the data and the collected images in slow motion or at accelerated speed. ### Claim 9 (depends on 1) The weld training system as defined in claim 1, wherein the instructions further cause the processor to provide one or more of the data or the collected images to a neural network to identify weld anomalies in the welding-type operation, the instructions to cause the processor to display the corresponding synchronized portions of the data and the collected images with identifiers to indicate the weld anomalies identified by the neural network. ### Claim 10 (depends on 1) The weld training system as defined in claim 1, wherein the weld training system is to receive the data from the welding-type equipment via at least one of a wireless communication or a wired communication. ### Claim 11 (depends on 1) The weld training system as defined in claim 1, wherein the instructions further cause the processor to: store the data and the collected images in a storage device;
