I would TIG it, less distortion and better results, but put lots of tack on 
it to minimize distortion and keep it from opening up too much.

  Subject: [PSUBS-MAILIST] welding sheet 
  metal
  
  Frank and or all you welding guru's 
  Any tips on welding sheet metal. I have my saddle tanks formed 
  and I am
  going to weld two pieces together.
   
  In my past experience I have found it difficult. Pourous welds 
  etc.
   
  One thought I had was to weld em for strength and then Braze over 
  the
  top. 
   
  I will be welding 18 gauge cold rolled with a 
  MIG
