WHAT FILLER ROD DO I USE TO JOIN 13-8 IT'S FOR MEDICAL TOOLS ?

why not use 13-8?
also known as AMS 5840

if it is not going to be heat treated after welding, then any number of filler rods would be work and weld much better than the 13-8.
for example, plain 308L filler wire wont have the strength of heat treated 13-8 but will certainly weld better.
