Hello everyone, I've recently begun learning about welding robots and have encountered some uncertainties that I hope those with more experience can help clarify.
I was discussing with a colleague who mentioned that when welding large parts, it's common practice to conduct touch-sensing initially to establish the part's position (similar to a global calibration). Then, for each subsequent weld, touch sensing is performed again (referred to as local calibration).
My question is, is this a typical procedure in the industry? And if so, how does the robot manage nested calibration?
Thanks and have a nice day
