Kwihlabathi elikhawulezayo lokuwelda kunye nokugquma, iingcali ziyayiqonda indlela ebaluleke ngayo ukusebenzisa izixhobo ezikumgangatho ophezulu ukuze kufezekiswe iziphumo ezigqibeleleyo. Kulapho ke iingcingo ze-alloy ze-nickel eziphezulu zisebenza khona. Le ngcingo yenzelwe ngokukodwa ukugquma kunye nokugquma i-alloys ezisekelwe kwi-nickel ezifana ne-625 okanye izinto ezifanayo, yenzelwe ukuba idlule ulindelo ngokwendlela esebenza ngayo, ukuqina kunye nokuguquguquka. Yenzelwe ukubonelela ngee-welds ezicocekileyo nezikumgangatho ophezulu kuyilo oluqinileyo, le ngcingo ivelele kwimarike ngenxa yokuguquguquka kwayo okuphezulu kunye nee-welds ezikhazimlayo.
Enye yezona nzuzo zibalaseleyo zeucingo lokuwelda lwe-nickel alloy ephezuluyimpawu zayo ezintle kakhulu zoomatshini kumaqondo obushushu aphezulu naphantsi. Nokuba imeko-bume injani na, iingcali zinokuqiniseka ukuba olu cingo lokuwelda luya kuqhubeka nokubonakalisa ukuqina okumangalisayo kunye nokuqina kwesakhiwo. Ukongeza, le ntsimbi yokuwelda inokumelana okuhle kakhulu nokugqwala kwemingxuma kunye noxinzelelo, okwenza ukuba ilungele iiprojekthi ezinje ngoshishino lweenkqubo zeekhemikhali, ubunjineli bolwandle, izinto ze-reactor zenyukliya, izixhobo zeenqwelo-moya kunye nezixhobo zolawulo lwezopolitiko.
Ukugcina ukuthembeka nokusebenza kubalulekile xa usebenza ngee-alloys eziphezulu ze-nickel kunye nezinto ezifanayo.Iingcingo zokuwelda ze-nickel alloy eziphezuluzenzelwe ukuqinisekisa iziphumo ezihambelanayo naphantsi kweemeko ezinzima. Olu cingo lusebenza kumanqanaba obushushu acetyiswayo ukusuka kwi-cryogenic ukuya kwi-540°C, lubonelela ngoxolo lwengqondo ekukhuseleni ukuguquguquka kobushushu. Oku kuluncedo ngakumbi kwizicelo ezibalulekileyo apho uzinzo lubaluleke kakhulu ekusebenzeni okuthembekileyo.
Ukwengeza,ucingo lokuwelda lwe-nickel alloy ephezuluivula indlela yokwanda kwemveliso kunye nokusebenza kakuhle. Ngobuchwepheshe bayo obuqinileyo bokumapha, yenza kube lula inkqubo yokunyibilikisa intsimbi egudileyo nengenamthungo, inciphisa iimpazamo kunye nokuphinda isebenze. Oku akugcini nje ngokusindisa ixesha elixabisekileyo, kodwa kunciphisa nenkunkuma yezinto ezibonakalayo, okwenza kube lukhetho olungabizi kakhulu kumashishini ahlukeneyo. Isiphumo sokugqibela kukuba ii-welds ezichanekileyo nezicocekileyo ezine-ductility egqwesileyo, eziqinisekisa ukusebenza okuhlala ixesha elide naphantsi kweemeko ezinzima.
Ngamafutshane, ii-electrode ze-alloy ze-nickel ephezulu zibonelela ngeenzuzo ezininzi kwiingcali kushishino lwe-welding kunye ne-cladding. Amandla ayo okuwelda nokugquma ii-alloys ezisekelwe kwi-nickel ngokulula, kuquka ne-625, anika isisombululo esithembekileyo kwiintlobo ngeentlobo zezicelo. Ukususela ekunikezeni ii-welds ezikhazimlayo nezisemgangathweni ophezulu ukuya ekuboniseni iipropati zoomatshini eziphezulu kumaqondo obushushu aphezulu, le ntambo ivumela iingcali ukuba zifumane iziphumo ezigqwesileyo. Ngenxa yokukwazi kwayo ukumelana nokugqwala kunye nokuxinezeleka, ibonakalise ukuba lukhetho oluhlala ixesha elide noluthembekileyo. Ukusetyenziswa kweiingcingo zokuwelda ze-nickel alloy ephezuluivula amathuba amatsha kwaye iqinisekisa ukugqitywa ngempumelelo kweeprojekthi kwiinkalo ezahlukeneyo njengeenkqubo zeekhemikhali, ubunjineli bolwandle kunye neenqwelo-moya.
