Dodge has made three types of frames, which require three types of fabrication/repairs.
The early Power Wagon frames, as mentioned, were stamped and are assembled using bolts and rivets, no welding. For some unknown reason, most likely a chronic problem reported to the factory, these frames began to be welded at specific points in the late 50's. At about the same time the Power Giants and later Sweptlines began using heat treated frames, still assembled using rivets and bolts, no welding is advised on those frames, except at certain miniscuel locations, noted in the Factory Technical Manual.
Frames built from about 2002 on are hydroformed, basically extruded under pressure using different metal properties, these frame are welded at nearly every possible location, however the added parts are 'sleeve fit' and non-qualified welding is still not advised.
Hot Rods, home builts etc. are normally built using mild steel which can be welded upon at just about any location by mid skill level welders.
Factory frames have been welded upon by the factory and by certified aftermarket installers for the factory, using factory specifications. A few factory manuals or weld details turn up from time to time, showing the methods and techniques required to be used by a qualified welder with top quality skills and equipment.
To do it correctly may cost more than the $300 purchase price of a replacement frame.
