If you don't normalize or heat treat a welded  4130 joint, isn't a "low temp" 
nickel silver filet better? My tests show it is! Heli arc welders make 
beautiful filets on 4130 but get imbrittlement!  Study crash results on 
sprint car crashes 4130 vs mild steel! The kit fox kit plane, uses miged mild 
steel. Drags need it we don't! JACK
