   Steel Weld Backing Plate

   First off let me say I "can" gap weld steel.  I prefer a good fit-up,   
   proper bevels, and most importantly, nobody inspecting my work, but...   
      
   I've got a situation where I cut a part in two with a grinder and a zip   
   disc to only use part of it, and now I've decided that was a mistake.   
   Or rather the application has evolved to a point where the original part   
   would be better.  I don't have to make it exactly like it was, but kinda   
   sorta close maybe might be nice.   
      
   If it was aluminum and I was in a similar situation I'd grab one of the   
   piece of stainless bar stock I keep for aluminum backing and just do it.   
     I'd probably clamp it up, weld it up from one side, back grind it with   
   a burr, and weld the other side.   
      
   This is steel.  While its not any kind of acceptable practice if I tried   
   the solution above it would weld right into the stainless steel backer.   
   Is there any shade tree backing I could use beside buying an expensive   
   piece of graphite?   
      
   I know.  I know.  The true correct shade tree engineering method is to   
   just gap weld it.  LOL.
