1. A weld defect detection method comprising:
receiving an input indicating a weld material and material thickness by a portable computing device;
determining, with the portable computing device, a detection protocol for the weld material and material thickness;
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;
recording thermographic data from the weld with the portable thermographic sensor according to the detection protocol;
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.
