Let's understand distortion! It will be the second time. Before you understand distortion and remove distortion, this is the only thing I would like to say. "There is nothing better than no distortion!" Straightening is very troublesome. It's tedious and time consuming. Why don't you devise a way to avoid distortion as much as possible by adding a little extra work during welding? I hope this video helps you in some way.
