If the thickness is more than what can be welded without filler metal by the given process, you have to, provided the filler is compatible with the base material.

What do you mean 'making welded pipe? The pipe seam welds are all autogenous and then fully annealed.
Are you welding a piece of 304L to a piece of duplex? If so then use the filler recommended for the duplex. Look in the welding guidelines published by Outokumpu.

My shop has to make a piece of larger diameter pipe. Some specs like A312 are autogenous like you mentioned however others such as A358 either require or allow the addition of filler metal. And still some that are autogenous allow a small precentage of filler metal for weld repairs. I do not have easy access to the list of ASTM pipe specs to determine what is allowed.
