Welding 17-4 pH to 304
Welding 17-4 pH to 304
(OP)
Current design has a 2"x2"x200"long bar of 17-4 pH welded to top of SS304 I beam. If we skip welded or spot welded, would the difference in heat shrinkage still cause warpage beween the 2 materials? If so, any solutions? The 17-4 is for 2 rails holding 2 wheels each at 10,000 lb/wheel.





RE: Welding 17-4 pH to 304
I understand that 17-4 PH is in fully heat treated condition and that the weld has no strength function.
If this is correct, then skip welding small fillet welds with ductile 300 series filler metal should be adequate.
Deformation would probably be reduced using a proper sequence from the center symmetrically towards the ends.
If this is not acceptable would a mechanical fastening system without welding be feasible?
