tly ran into someone and was discussing IR thermography with them. He said his company used xray techniques to evaluate welds as well as IR. What am I missing. How can you evaluate a weld with IR.
I cannot think of a way that IR would substitute for Xray in weld quality. Temp sticks work quite well for the welding process and the PWHT guys monitor while cooking, so I would like to know where IR comes in... my curiosity is aroused.
