I-flash butt welding bubuchule obusetyenziswa ngokubanzi kwimizi-mveliso yokuvelisa kunye nokwakha ukudibanisa isinyithi.Kubandakanya ukusetyenziswa kwamandla aphezulu kunye noxinzelelo lokudala ibhondi eqinile, ehlala ixesha elide phakathi kweentsimbi ezimbini.Enye inkalo ebalulekileyo yenkqubo ye-flash butt welding i-preheating, edlala indima ebalulekileyo ekuphumezeni ii-welds eziyimpumelelo.Kweli nqaku, siza kuhlolisisa ukubaluleka kokushisa kwangaphambili kunye nemiphumo yayo kumgangatho kunye nokunyaniseka kwe-flash butt welds.
Ukushisa kwangaphambili yinkqubo yokunyusa ubushushu bezinto ezifakwe kwi-welded ngaphambi kokuba usebenze ngokufanelekileyo.Ngokuqhelekileyo kwenziwa kusetyenziswa ukufudumeza kwe-induction, amadangatye egesi, okanye iindlela zokuxhathisa ukufudumeza.Injongo ephambili yokufudumeza kwi-flash butt welding kukunciphisa uxinzelelo lwe-thermal kunye nokwahluka kweqondo lokushisa okunokuthi kwenzeke ngexesha lenkqubo ye-welding.
- Ukunciphisa Uxinzelelo: Ukushisa kwangaphambili kunceda ukunciphisa uxinzelelo lwangaphakathi kwizinto ezidityanisiweyo.Xa izinyithi zifudunyezwa ngokukhawuleza ngexesha le-welding, ziyanda, kwaye njengoko zipholile, ziyancipha.Oku kwandiswa ngokukhawuleza kunye nokucutheka kunokubangela uxinzelelo olushiyekileyo ngaphakathi kwendawo edibeneyo.Ukushisa kwangaphambili kuvumela ukutshintshwa kweqondo lokushisa ngokuthe ngcembe, ukunciphisa umngcipheko wokuqhekeka kunye nokuphazamiseka kwiinqununu ezidibeneyo.
- UkuPhuculwa kwezinto eziPhuculweyo: Ngexesha le-flash butt welding, izixhobo ziphantsi koxinzelelo olunzima kunye nezangoku, ezibangela ukuba zibe ne-malleable kakhulu.I-preheating ithambisa izinto eziphathekayo, ibenze i-ductile ngakumbi kwaye ikhuthaze ukuhamba kwezinto ezingcono.Oku kuphucuka kokuhamba kwezinto kuqinisekisa ukuba iintsimbi zidibanisa ngokutyibilikayo, zenza ibhondi eyomeleleyo nethembekileyo.
- Ukunciphisa Ukuqina kunye noBubrittleness: Ukupholisa ngokukhawuleza emva kwe-welding kunokukhokelela ekubunjweni kwe-microstructures enzima kunye ne-brittle kwi-joint welded.Ukushisa kwangaphambili kunciphisa inkqubo yokupholisa, ukuvumela ukubunjwa kwezinto ezincinci kunye ne-ductile microstructures.Oku, kwandisa ukuqina kunye ne-ductility ye-weld, ukunciphisa umngcipheko wokuqhekeka kunye nokungaphumeleli.
- Ukumelana ne-Corrosion: Ukushisa kwangaphambili kunokuba nefuthe elihle kwi-corrosion resistance of the joint welded.Ngokukhuthaza ukubunjwa kwe-weld ehambelanayo kunye ne-brittle encinci, ukufudumala kwangaphambili kunceda ukunciphisa ukuxhatshazwa kwe-joint ku-corrosion kunye nezinye iindlela zokutshatyalaliswa kwezinto.
Ukuqukumbela, ukufudumeza kuqala linyathelo elibalulekileyo kwi-flash butt welding, njengoko inegalelo kumgangatho wonke kunye nokuthembeka kwe-weld.Ngokunciphisa uxinzelelo lwangaphakathi, ukuphucula ukuhamba kwezinto, ukunciphisa ukuqina kunye nokuqina, kunye nokuphucula ukuxhathisa kwe-corrosion, ukufudumala kwangaphambili kuqinisekisa ukuba i-welded joint idibana nemigangatho yokusebenza efunekayo kunye nokuqina.Abavelisi kunye nabavelisi kufuneka baqwalasele ngononophelo iiparamitha zokufudumeza ukufezekisa impumelelo ye-flash butt welds kwizicelo ezahlukeneyo.
