It's welded and very strong. At least the stuff I've purchased has been.
  Much of the top rail for chain link fencing MAY be welded.  But I
have installed some that was NOT.  It LOOKED OK at first glance
but upon close inspection it was rolled and then hot-dipped
galvanized.  The zinc gave it the "appearance" of pipe.   But it
was not structural.   Under relatively small loads it would split
along the seam.
  
Just a word of caution about chain link fence rail.   Not to mention
that water pipe is NOT a structural element and you will not find
structural specs on it other than burst strength.  
Nothing beats doing the engineering and selecting the proper material.
