Yeah trick is to let it cool otherwise you just twist the nut back off but as you say the heat is concentrated through the stud and really helps when it contracts again.
I point the torch directly at the stud welder is turned up quite high but when building up only use short burst it even works with alloy, first time I did it was with a broken stud in a alloy thermostat housing on a Skoda.
Had the front hub from a Transit brought to me today with a broken stud so thought I would take some pics to show how I removed it with a welder.
Allen key was just to show that it had broken approx. 5mm or so below surface.
First build up with weld until it is flush with surface then place a...
