I have noticed joining two pieces of metal say 12" long sometimes the whole 12" is welded another time the weld is 1.5" long then a gap of 1.5" and so on,
what is the reason for this weld and a gap?

The reason for the gap is to keep the metal from warping , concentrated heat will put a nice curve where you don't want one if you don't break it up and skip a little here and there . this is especially true for thin metal .
