From GAWDAwiki

Joint clearance is the distance between the faying surfaces of a joint. Due to thermal expansion of the work-pieces in brazing, joint clearance may vary as work-pieces are heated and cooled.^[1]>

Gap between surfaces to be joined by welding, where the gap will help ensure that the weld filler penetrates to the needed depth in the base metal.^[2]
