Welded Alloy Wheel Repair & MOT

Hello,

I just picked up a used car last month and noticed the rear alloy wheels aren't holding air too good.
I removed them and discovered one had a really bad leak at a buckle on the rim

Checking the MOT history, i can see it was an advisory on the buckles previously.

I had the buckle from the RIM removed and the repairer found a small crack.
The crack was repaired by welding the alloy wheel.

The repair is sound as the wheel no longer leaks are but the weld wasn't ground down and smoothed so it's visible.

Will this be an MOT failure now even if the repair is solid?

Lots of websites who repair wheels say it's not an MOT failure but section 5.2.2 of the manual has me a  bit worried.

I'm not a tester myself but used to help testers on the ramp 20 years ago when i was an apprentice. I work in IT now but still do some home mechanics as a hobby.
