@welding.sinh: Restricted-access TIG root pass on a stainless steel lube oil line for a turbine bearing! With only a 10 cm gap under the column and adjacent piping in the way, getting a direct view is impossible. You can only look sideways with one eye, getting a partial, blurry view of the joint—meaning you can't fully see the inner root penetration. A quick lesson for apprentice welders & students: working with limited sight isn't just about what you see; it's about muscle memory, feeling the arc, and controlling the puddle by experience.
