Trunk lid cracking

Hey everyone,
I was curious if this issue is common amongst our cars. These two pics are just above the trunk hinges on the trunk lid.
I thought maybe because my car has a trunk popper and being an AHB car, using that often put added stress in this area?
I was planning on drilling the cracked ends and hopefully trying to weld the cracks.
