Reply to comment by projekt_treadstone in [P] Defect detection system for welding by hotspicynoodles

it certainly does not only depend on gas flow rate but also current and arc length, so there are 3-4 variables. I guess I'm looking towards multi variate time series prediction method then

Now it makes more sense and if you can gather some data of defect image and non defect image of welding then it can learn from 2 modalities (time series and image) and might generate better results. One of my friend used this method for similar defect analysis. You might need to do some feature analysis to find some pattern as non useful or outlier feature can produce unnecessary noise and pose difficulties for optimization.
