Ukusebenza kunye nokuthembeka kwezakhiwo ezidityanisiweyo kwiindawo ezifuna kakhulu kuxhomekeke kakhulu ekukhetheni iintsimbi zokuzalisa ezifanelekileyo. Ukuze kudityaniswe ii-alloys zentsimbi engagqwali ezinobushushu obuphezulu kunye nezingagqwaliyo, ukhetho lwesixhobo esithileIiAlloys Electrodes Welding IntongaIbaluleke kakhulu. Udidi lwe-AWS A5.4 E310-16 lubonisa umgangatho ophezulu we-electrode yokuwelda yentsimbi engagqwaliyo eyilelwe ukubonelela ngee-welds ezinokuthenjwa nezihlala ixesha elide kwiintlobo ngeentlobo zezicelo ezinzima.
Le Alloys Electrodes Welding Rod ethile, eyaziwa ngokuba yi-A402, yi-electrode yentsimbi engenasici ye-chromium26-nickel21 ecocekileyo ene-titania-calcium coating. Ulwakhiwo lwekhemikhali lwentonga lubalulekile ekusebenzeni kwayo, lubonelela ngokumelana okugqwesileyo ne-oxidation kunye nokugqwala kumaqondo obushushu aphezulu, adla ngokufikelela kwi-2100.°F (1150)°C). Umxholo ophezulu we-alloy yocingo oluphambili uqinisekisa ukuba isinyithi se-weld esigciniweyo sigcina isakhiwo kunye neempawu zaso phantsi koxinzelelo lobushushu.
Uphawu oluphambili lwale ntoIiAlloys Electrodes Welding Intongayiyo indlela yokugquma kunye neempawu zayo zokusebenza. I-titanium-calcium coating yenza kube lula ukubethelela i-arc, ukutsha kwe-arc okuzinzileyo, kunye nokuchithakala okuncinci, okubangela ukubonakala okuthambileyo, okuthandekayo ngobuhle. I-electrode inika ukusebenza okuhle kakhulu kwi-welding yeendawo zonke, kubandakanya ukuthe nkqo kunye ne-overhead, okubonelela ngokuguquguquka okukhulu ngexesha lokwenziwa kunye nemisebenzi yokulungisa. I-slag idla ngokuziphakamisa kwaye kulula ukuyisusa, nto leyo ephucula ukusebenza kakuhle kwe-welding.
Eyona nto iphambili esetyenziswa kwi-electrode ye-E310-16 kukuwelda kweentsimbi ezimelana nobushushu zohlobo lwe-25Cr-20Ni, ezifana ne-HK40 kunye ne-310S. Isetyenziswa kakhulu ekwenziweni nasekugcinweni kwezinto ezinobushushu obuphezulu, kuquka iindawo ze-furnace, iityhubhu zokulungisa, kunye nezinye izixhobo ze-pyrolysis. Le ntonga yokuwelda ye-electrodes ye-alloy idla ngokukhethwa ukuze iwelda eyahlukileyo phakathi kweentlobo ezahlukeneyo zentsimbi engagqwali okanye kwiindawo ezigqumayo ezifuna ukumelana nobushushu obuphezulu.
Udidi lwe-AWS A5.4 E310-16 luchaza ukusebenza okuphezuluIiAlloys Electrodes Welding Intongaibalulekile kumashishini apho uzinzo lobushushu kunye nokumelana nokugqwala kubaluleke kakhulu. Ukusebenza kwayo okuhlala kufana kunye neempawu zesinyithi eziweld ezibalaseleyo kwenza ukuba ibe lukhetho oluthembekileyo lokuqinisekisa ukuhlala ixesha elide kunye nokhuseleko lwezinto ezibalulekileyo ezishushu kakhulu. Ukusetyenziswa ngokuchanekileyo kwale welding ekhethekileyo sisiseko sokwenziwa komgangatho kwicandelo le-petrochemical kunye nokuveliswa kwamandla.
