Izinto ezilinganayo: 1.4317 GX4CrNi13-4,1.4313 X3CrNiMo13-4,1.4407 GX5CrNiMo13-4,1.4414 GX4CrNiMo13-4,ACI Gr. CA6NM

I-ER410NiMo yintambo eqinileyo yentsimbi engagqwaliyo ye-martensitic ene-chemical composition ene-11.0 – 12.5% ​​Cr, 4.0 – 5.0% Ni, kunye ne-0.40 – 0.70% Mo. Ifanelekile kwi-gas shielded welding (njenge-TIG/MIG) kuzo zonke iindawo. Ngexesha le-welding, i-arc izinzile, kwaye isinyithi esigciniweyo sibonisa ukumelana okuhle kwe-cavitation, ukumelana nokuguguleka kwesanti,

kunye neempawu zoomatshini. Akufuneki ukuba kufudunyezwe ngaphambi kokuba kufakwe i-welding; unyango lobushushu emva kokuwelda (PWHT) kwi-580 ~ 620℃ iiyure ezi-2 (kulandelwe kukupholisa umoya, i-AC) luyacetyiswa ngokweemfuno zokusetyenziswa. Isinyithi esigciniweyo siyakwazi ukutshixwa kwaye sifanelekile kwizixhobo zoxinzelelo.

Yenzelwe ukuwelda intsimbi eqhotsiweyo ye-ASTM CA6NM, intsimbi engagqwaliyo ye-410/410S/405, kunye neentsimbi ezifanayo ze-13%Cr – 4%Ni. Usetyenziso oluqhelekileyo lubandakanya izixhobo zoxinzelelo (ezihambelana nemigangatho yesitya soxinzelelo), iiblade zeturbine, iivalvu, iipayipi zoxinzelelo oluphezulu, kunye neendawo zesakhiwo ezifuna ukugqwala kunye nokumelana nokuguguleka.

Ipharamitha yokuWelding ecetyiswayo

Igesi yokukhusela: I-Argon (Ar) okanye i-Ar+1-2% O2 (yokuwelda i-TIG/MIG, lungisa ngokweenkqubo ezithile).

 

Isaziso

1. Qinisekisa ukuba umphezulu wentambo ucocekile kwaye awunayo ioyile, umhlwa, okanye ukufuma ngaphambi kokuba uyisebenzise ukuze uphephe ukuphazamisa umgangatho wokuwelda.

2. Gcina ubunyulu begesi kunye nesantya sokuhamba esifanelekileyo ukuthintela ukuqhekeka kunye nokuqhekeka okubangelwa yi-hydrogen.
