Isikhokelo Esipheleleyo Seentambo Zokuwelda Zentsimbi Engagqwaliyo: AF2209-16 (AWS E2209-16)

Xa udibanisa intsimbi engagqwaliyo, ukusebenzisa i-electrode efanelekileyo kubalulekile ekufezekiseni i-weld eqinileyo nehlala ixesha elide.AF2209-16 (AWS E2209-16)yi-electrode ethandwa kakhulu kushishino lokuwelda. Le electrode yi-electrode yentsimbi engenasici ephindwe kabini ene-nitrogen engaphantsi kakhulu ene-calcium titanium coating, nto leyo eyenza ukuba ibe lolona khetho luphambili lokusetyenziswa kokuwelda.

I-electrode ye-AF2209-16 yenzelwe ukuwelda intsimbi engagqwali ye-duplex, eyaziwa ngokuxhathisa kwayo ukugqwala kunye namandla aphezulu. Ukongezwa kwe-nitrogen kwi-electrode kunceda ukuphucula ukuxhathisa kwe-weld kwi-pitting kunye ne-crevice corrosion, okwenza ifaneleke ukusetyenziswa kwiindawo ezinzima ezifana namashishini okucoca ulwandle kunye neekhemikhali.

Enye yeempawu eziphambili ze-electrode ye-AF2209-16 kukuqukethwe kwayo kwekhabhoni ephantsi kakhulu, okunceda ukunciphisa ukwakheka kweekhabhoyidi kwisinyithi se-weld, ngaloo ndlela kugcinwa ukumelana nokugqwala kwentsimbi engagqwaliyo. Ukongeza, i-calcium titanium coating kwi-electrode inika iimpawu ze-arc ezizinzileyo kunye nokususwa kwe-slag ngokulula, okubangela ukuba i-weld bead icocekile kwaye igudileyo.

Xa usebenzisa i-electrode ye-AF2209-16, kubalulekile ukulandela iiparameter zokuwelda ezicetyiswayo ukuze ufumane iziphumo ezilungileyo. Oku kuquka ukukhetha i-amperage efanelekileyo, i-voltage kunye nesantya sokuhamba ngokusekwe kubukhulu bentsimbi engatyiwayo eza kuwelda. Unyango olufanelekileyo lwangaphambi nasemva kokuwelda, olufana nokufudumeza kwangaphambili kunye nokuthuthwa emva kokuwelda, kufuneka luqwalaselwe ukuqinisekisa ukuthembeka kwe-weld kunye nokunciphisa umngcipheko wokugqwala.

Ngamafutshane, ii-electrode zentsimbi engagqwaliyo ze-AF2209-16 (AWS E2209-16) ziyindlela ethembekileyo yokudibanisa iintsimbi ezingagqwaliyo ezimbini, zibonelela ngokumelana nokugqwala okugqwesileyo, amandla aphezulu, kunye nokulula kokusetyenziswa. Ngokuqonda ukwakheka kwayo okwahlukileyo kunye nokulandela iindlela zokudityaniswa ezicetyiswayo, abadibanisa iintsimbi banokufikelela kwiintsimbi ezisemgangathweni ophezulu ezihlangabezana neemfuno ezingqongqo zezicelo ezahlukeneyo zoshishino. Nokuba zisetyenziselwa ukwenza imithambo yoxinzelelo, imibhobho okanye izinto zokwakha, i-electrode ye-AF2209-16 sisixhobo esixabisekileyo sokufezekisa ukusebenza okuphezulu kwe-welding kwizicelo zentsimbi engagqwali.
