How do we correctly do resistance/spot weld by use of arc or TIG welder (if the difference is big explain each of this weld separately) to join piled up two bolt rings of the same thickness 2-2.5 mm and center diameters but largely different outer diameters
Can one even do this? I understand a spot weld to be a resistance weld procedure where the two parts are compressed and high current is applied and fusing the material at a "spot" location.
I suppose one could do a hole or slot weld effectively fusing at a location.
