I have the Krauser side bags on my '75 R90/6. The racks are chrome. The one on the right side has a crack in the weld that holds one part of it together. It is cracked all the way through for almost one half of it's circumference. So I figure to have this welded and wonder (since I don't do welding) do I look for MIG Welding or TIG Welding or just what do I ask for. This should be a small job and I can take the racks off if need be but do I or should I remove the racks to weld them? Can it be repaired in place? The metal inside the cracked area is rusted. Should I clean the rusted part down to bare metal before looking for a welder? What should this cost me?
