Xa kudityaniswa intsimbi engagqwaliyo, ukukhetha i-electrode kubalulekile ukuze kufunyanwe i-weld esemgangathweni ophezulu nehlala ixesha elide. Kulapho keAF2209-15 (AWS E2209-15)ingena. Le electrode yentsimbi engenasici ephindwe kabini ene-nitrogen ekhabhoni ephantsi kakhulu yenzelwe ukuhlangabezana neemfuno zokuwelda ezifuna kakhulu. Ngomgqumo wayo ophantsi we-hydrogen, i-AF2209-15 iqinisekisa umgangatho kunye nokusebenza kakuhle kokuwelda.
I-AF2209-15 yenzelwe ukuwelda iintsimbi eziqinileyo ezimbini kwaye inika ukumelana nokugqwala okugqwesileyo kunye namandla aphezulu. Umxholo wayo wekhabhoni ophantsi kakhulu unciphisa umngcipheko wokuna kwe-carbide, iqinisekisa iipropati ezintle zoomatshini kunye nokudityaniswa. Umxholo we-nitrogen uphucula ngakumbi ukumelana nokugqwala kwe-weld kwi-pitting kunye ne-crevice, okwenza i-AF2209-15 ifaneleke kakhulu kwizicelo ezibalulekileyo kumashishini afana neoyile negesi, ukucubungula iikhemikhali kunye nobunjineli bangaphandle.
Enye yeempawu eziphambili ze-AF2209-15 kukugqunywa kwayo nge-hydrogen ephantsi, okunciphisa kakhulu umngcipheko wokuqhekeka okubangelwa yi-hydrogen. Oku kuyenza ifaneleke ukusetyenziswa kwe-welding apho i-hydrogen embrittlement ixhalabisa, okuqinisekisa ukuthembeka kunye nobude bexesha le-weld. Iimpawu ze-electrode ezizinzileyo kunye neempawu ze-welding ezigudileyo zinegalelo ngakumbi ekusetyenzisweni kwayo ngokulula kunye nokusebenza rhoqo, okubangela imisebenzi ye-welding esebenzayo nethembekileyo.
Ukongeza ekusebenzeni kakuhle kwe-welding, i-AF2209-15 yenzelwe ukuba isebenziseke lula kwaye ilula. Nokuba isetyenziselwa iindawo ezithe tyaba, ezithe tye, ezithe nkqo okanye eziphezulu, le electrode inika ii-welds ezihambelanayo nezisemgangathweni ophezulu. Ifanelekile kwiindidi ezahlukeneyo zezixhobo ezisisiseko, kuquka ii-UNS S31803, S32205 kunye neentsimbi eziqinileyo ze-S2205, nto leyo eyenza ukuba ibe sisisombululo esiguquguqukayo kwiindidi ezahlukeneyo zezicelo ze-welding.
Ngokubanzi, i-AF2209-15 imisela umgangatho omtsha wee-electrode zokuwelda zentsimbi engagqwaliyo, ezibonelela ngokusebenza okungenakuthelekiswa nanto, ukuthembeka kunye nokuguquguquka. Inomxholo we-nitrogen ophantsi kakhulu wekhabhoni, i-hydrogen coating ephantsi kunye nokumelana nokugqwala okuphezulu, le electrode lolona khetho lubalaseleyo lomgangatho ophezulu wokuwelda kunye nokuqina. Nokuba usebenza kwiiprojekthi ezibalulekileyo zeziseko zophuhliso okanye usetyenziso lobunjineli obuchanekileyo, i-AF2209-15 sisisombululo esikhethiweyo kwimingeni enzima yokuwelda.
