In my case it is not possible, I always leave a gap I didn't see or holes in middle of dot. I have seen pros videos and they reweld every time. When you are quick zapping dots trying to get penetration and not blow thru and not heat up, you will miss a few spots. When you shine a light behind the weld......yipes!
My quick air gun has seemed to prevent any issues with warp or I am lucky.
