AISI 630(PH:석출경화강) TO LOW ALLOY(SNCM431/ P NO:4)
상기 이종 재질을 용접하려고 합니다.
용접부는 BUTT WELDING이고 용접두께는 10mm입니다.
관련서적(용접기술실무/용접재료와코드)을 찾아봐도
이런경우 용접봉이 selection되여 있지
않고있읍니다.
어떤용접봉 및 용접후 처리 방법에 대해 고수님들의
의견 바랍니다

17Cr-4Ni (Type 630);
Normally AWS E/ER630 (UNS S17480) welding consumables should be considered to provide welds with mechanical properties matching those of the base metal (17-4 PHSS or SNCM431). The GMAW or GTAW with ER630 (UNS S17480) is the most popular welding process.
Please find the following for more detail welding procedures;

When high weld strength is not needed and/or corrosion resistance is more important, a standard austenitic stainless filler, such as E/ER308L, should be considered.
Meanwhile when designing the weld joint, care should be exercised to avoid stress concentrators, such as sharp corners, threads, and partial-penetration welds.
Hope this helps,
