Abstract
Methods and systems for detecting weld defects, and methods for manufacturing vehicles using such methods or systems, are provided. An exemplary method includes receiving an input indicating a weld material and material thickness by a portable computing device and determining, with the portable computing device, a detection protocol for the weld material and material thickness. Further, the method includes communicating the detection protocol from the portable computing device to a portable heating source and to a portable thermographic sensor, heating a weld with the portable heating source according to the detection protocol, and recording thermographic data from the weld with the portable thermographic sensor according to the detection protocol. Also, the method includes communicating the thermographic data from the portable thermographic sensor to the portable computing device, and analyzing the thermographic data to detect whether the weld includes a defect and/or determine type, dimension and location of the defect.
