Data acquisition using a purge plug
A welding system using a purge plug for data acquisition. In one example, a purge plug includes purge plug component having a sealing structure. The sealing structure is configured to abut a surface of a hollow device and to form a seal between the sealing structure and the hollow device. The purge plug also includes a sensor at least partly disposed in the purge plug component, the sealing structure, or some combination thereof. The purge plug component is configured to be disposed on a workpiece having the hollow device to purge an undesired gas from the workpiece.
1. A purge plug system comprising:
a purge plug component comprising a sealing structure, wherein the sealing structure is configured to abut a surface of a hollow device and to form a seal between the sealing structure and the hollow device when the purge plug component is inserted into the hollow device; and
a sensor integrated with the sealing structure and configured to contact the surface of the hollow device when the purge plug component is inserted into the hollow device, wherein the purge plug component is configured to be disposed on a workpiece having the hollow device to purge an undesired gas from the workpiece, and wherein the sensor is configured to detect a parameter related to the workpiece.
