It's probably not a big deal, but if you are concerned, you can either (1) have someone MIG weld the area (be sure to remove any interior carpet or insulation before doing this or (2) drill and bolt the broken weld with suitable hardware.
I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
