You don't need to weld the steering column. I poured epoxy resin into the gap and it worked fine. You just need something hard enough to replace the original rubber that erodes away over time. Cost me 3 quid from Wilkos
The original non-welded columns with rubber in do remove some steering wheel vibration, so are a better option than a bodge on a road car.
