Iialloyi zobhedu zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokuhanjiswa kwawo kombane okugqwesileyo, ukuhanjiswa kwe-thermal, kunye nokumelana nokubola. Eli nqaku lijolise kubuchule bokuwelda iialloyi zobhedu usebenzisa umatshini wokuwelda we-inverter ophakathi. Ukuqonda iingqwalaselo ezithile kunye neenkqubo zokuwelda ialloys zethusi kubalulekile ekufezekiseni iiwelds eziyimpumelelo nezithembekileyo kwizicelo zengxubevange yobhedu.
Ukukhethwa kwezinto:
Khetha i-alloy yobhedu efanelekileyo kwisicelo esijoliswe kuyo. I-alloys yobhedu ibonisa iimpawu ezahlukeneyo zomatshini kunye neempawu ze-weldability, ngoko ke kubalulekile ukukhetha i-alloy ehlangabezana neemfuno ezifunwayo. Iialloyi zobhedu eziqhelekileyo ezisetyenziswa kwi-welding applications ziquka ubhedu, ubhedu, kunye ne-copper-nickel alloys.
Uyilo oludibeneyo:
Khetha idizayini efanelekileyo edibeneyo eqinisekisa ukulungelelaniswa ngokufanelekileyo kunye nokulungelelaniswa kwamacandelo e-alloy yobhedu. Uyilo oludibeneyo kufuneka lunikeze ukufikelela okwaneleyo kokubekwa kwe-electrode kwaye kuququzelele ukuhanjiswa kobushushu obusebenzayo ngexesha le-welding. Iindidi ezidityanisiweyo eziqhelekileyo ze-alloys zobhedu ziquka i-lap joints, i-butt joints, kunye ne-T-joints.
Ukhetho lwe-Electrode:
Khetha i-electrodes eyenziwe kwizinto ezihambelanayo kunye ne-alloys yobhedu. Ii-electrode zobhedu zeTungsten ziqhele ukusetyenziswa ngenxa yokumelana nobushushu obuphezulu kunye nokuhanjiswa kombane okugqwesileyo. Khetha ubungakanani be-electrode kunye nemilo esekelwe kuyilo oluthile oludibeneyo kunye neemfuno ze-welding.
Imilinganiselo yeWelding:
Lawula iiparamitha ze-welding ukufezekisa iziphumo ezichanekileyo xa udibanisa i-alloys zethusi. Iiparameters ezifana ne-welding current, ixesha, amandla e-electrode, kunye nexesha lokupholisa kufuneka lihlengahlengiswe ngokusekelwe kwi-alloy yobhedu ethile. Ukuqhuba iiwelds zovavanyo ukumisela iiparamitha ezifanelekileyo ezibonelela ngokudibeneyo kunye nokungena ngaphandle kokungenisa ubushushu obugqithisileyo.
Irhasi yokuKhusela:
Sebenzisa igesi efanelekileyo yokukhusela ngexesha lenkqubo ye-welding ukukhusela i-weld pool etyhidiweyo kunye ne-electrode ekungcoleni kwe-atmospheric. Iigesi ze-inert ezifana ne-argon okanye i-helium ziqhele ukusetyenziswa njengeegesi ezikhuselayo kwii-alloys zobhedu. Qinisekisa ukugqunywa kwegesi okufanelekileyo ukuthintela i-oxidation kunye nokufezekisa i-welds ecocekileyo kunye nesandi.
Ukufudumeza kwangaphambili kunye ne-post-weld:
Ukufudumala kwangaphambili kunye ne-post-weld kungadingeka kwii-alloys ezithile zobhedu ukulawula umjikelezo we-thermal kunye nokunciphisa ukuphazamiseka. Ukufudumala umdibaniso kunokunceda ukunciphisa umngcipheko wokuqhekeka, ngelixa ukufudumeza kwe-post-weld kunokunciphisa uxinzelelo olushiyekileyo kunye nokuphucula umgangatho we-weld jikelele. Landela iinkqubo ezicetyiswayo zokufudumeza kwi-alloy yobhedu edityanisiweyo.
Ukucocwa nokuGqiba emva kweWeld:
Emva kwe-welding, susa nayiphi na i-residues ye-flux, i-oxides, okanye i-contaminants kwindawo ye-weld usebenzisa iindlela ezifanelekileyo zokucoca. Oku kuqinisekisa ingqibelelo kunye nenkangeleko yobuhle bomdibaniso odibeneyo. Iinkqubo zokugqiba ezifana nokusila okanye ukupholisa zingaqeshwa ukuze kuphunyezwe ubushelelezi obufunwayo bomgangatho kunye nokubonakala.
Welding copper alloys kunye medium frequency inverter indawo welding umatshini kufuna ingqalelo ngononophelo ukhetho izinto, uyilo ngokudibeneyo, ukhetho electrode, parameters welding, ukusetyenziswa kwegesi ekhuselayo, kunye neenkqubo zokufudumeza kwangaphambili kunye ne-post-weld. Ngokulandela obu buchule, i-welders inokufezekisa i-welds ethembekileyo kunye nekhwalithi ephezulu kwizicelo ze-alloy zethusi. Izenzo ezichanekileyo ze-welding zifaka isandla ekuthembekeni kwesakhiwo, ukuqhutyelwa kombane, kunye nokumelana nokubola kwezinto ezidibeneyo, ukuqinisekisa ukusebenza kwazo kunye nokuphila ixesha elide kumashishini ahlukeneyo.
