Inkcazo

I-E410NiMo-15 yi-electrode yokuwelda yentsimbi engagqwali ye-martensitic ene-hydrogen sodium coating ephantsi, equlethe i-11.0-12.5% Cr, 4.0-5.0% Ni, kunye ne-0.40-0.70% Mo. Ifanelekile kwi-arc welding yentsimbi ekhuselweyo (i-SMAW) ene-arc ezinzileyo, i-spatter encinci, kunye nokuqhekeka kwe-slag okugqwesileyo. Isinyithi esigciniweyo sinika amandla aphezulu, ukumelana nokugqwala okuhle, kunye nokumelana nokuqhekeka. Kucetyiswa ukufudumeza kwiindawo zokusebenza ezixineneyo, kwaye unyango lobushushu emva kokuwelda (i-PWHT) luyimfuneko kwi-580~620℃ (iiyure ezi-1-2, ukupholisa umoya, i-AC).

Isicelo

Ilungele ukuwelda intsimbi eqhotsiweyo ye-ASTM CA6NM, iintsimbi zochungechunge lwe-13%Cr-4%Ni (umz., i-Cr13Ni4Mo, i-Cr13Ni5Mo), kunye neentsimbi ezifanayo ze-martensitic stainless. Izicelo eziqhelekileyo ziquka ukuwelda ukulungisa ii-hydropower turbine runners, imizimba yeevalvu, iipayipi zoxinzelelo oluphezulu, kunye nomphezulu wezinto ezigutyungelwe yi-cavitation. Ikwasetyenziselwa ukulungisa iindawo eziqinileyo ezinganyangekiyo njengee-crusher rolls kunye nee-pump casings.
