Anyone experience how to accomplish join correctly of two wide rings piled up the smaller diameter one on the larger one just by the way of plug/slt welding but here and now the join work and method is replaced by the shrink fitting from ambient temperature to other greatly different one thence it's being fitted before getting back to the ambient
ring 1
hole d = 20 mm
OD = 30 mm
thickness = 1.5 mm
ring 2
hole d = 20 mm
OD = 55 mm
thickness = 2.5-3 mm
