Intshayelelo
Kwimveliso yesinyithi kunye nemveliso, i-zinc{0}}izinto ezigqunyiweyo zisetyenziswa kakhulu ngenxa yokumelana nokugqwesa kwazo okugqwesileyo kunye nomtsalane wokuhombisa. Nangona kunjalo, xa ezi mathiriyeli kufuneka zidityaniswe kusetyenziswa okuphakathioomatshini bokuwelda indawo rhoqo, ubukhulu be-zinc yokugquma buhlala buba yinto ebalulekileyo echaphazela ubunzima be-welding. Eli nqaku liphonononga lo mbuzo: "Ngaba i-zinc ejiyileyo iyatyabeka yenza i-welding ephakathioomatshini bokuwelda indawo rhoqoucela umngeni ngakumbi?" kwaye ibonelela ngezisombululo ezisebenzayo ukulungisa le mingeni.
Impembelelo yeZinc yoKutyabeka ukutyeba kubunzima be-Welding
Umsebenzi oyintloko we-coating ye-zinc kukukhusela isiseko sesinyithi kwi-corrosion, kodwa ubukho bayo budibanisa inkqubo ye-welding. Ngokukodwa, i-zinc etyebileyo yokugquma yonyusa imiceli mngeni ye-welding. Okokuqala, umaleko we-zinc unokumelana nombane ophakamileyo, okukhokelela ekwandeni kokumelana nokunxibelelana ngexesha le-welding kunye nokumelana okuphezulu kwendawo kwindawo ye-weld, echaphazela umgangatho we-weld kunye namandla. Okwesibini, i-thermal conductivity ye-zinc ikhawuleza ukuchithwa kobushushu ngexesha le-welding, ifuna imisinga ye-welding ephezulu okanye amaxesha amade e-welding ukufikelela kwiziphumo ezifanelekileyo. Ukongezelela, inkqubo ye-welding inokuvelisa i-gases eyingozi kunye ne-fumes evela kwi-coating ye-zinc, ibeka ingozi kwindawo yokusebenza kunye nempilo yomsebenzisi.
Izisombululo
Ukujongana nobunzima bokuwelda obuvezwa ziingubo ezishinyeneyo ze-zinc, qwalasela ezi ndlela zilandelayo:
Lungisa i-Welding Parameters:
- Lungiselela i-welding yangoku, ixesha, kunye noxinzelelo olusekwe kubukhulu be-zinc. Ukwaleka okuthe kratya, yandisa ikhoyo ngoku kwaye wandise ixesha le-welding ukuqinisekisa igalelo elaneleyo lobushushu kunye nokunyibilika okufanelekileyo. Lungisa uxinzelelo lokukhuthaza ukudibanisa okwaneleyo kwesinyithi esinyibilikisiweyo.
Lungiselela UKhetho lwe-Electrode:
- Khetha izinto ze-electrode ezine-conductivity ephezulu kunye nokumelana nokugqoka. Ii-electrode eziphambili zinciphisa ukuguga kunye nokulahleka kobushushu, ziphucula ukusebenza kakuhle kwewelding kunye nomgangatho wezinc{1}}ezigqunyiweyo zokusebenza.
Phucula iWorkpiece yokuCoca:
- Coca ngokucokisekileyo iindawo phambi kokuba welding ukususa ioli, iioksidi, kunye nezingcolisi. Iindlela zokusila ngoomatshini okanye iindlela zokucoca iikhemikhali ziyacetyiswa kwi-zinc eshinyeneyo yokugquma ukuze kuncitshiswe ukuxhathisa koqhagamshelwano kunye nokukhutshwa kwerhasi.
Phucula iVentilation:
- Ukomeleza iinkqubo zokungenisa umoya ukuze kupheliswe iigesi eziyingozi kunye nomsi owenziwe ngexesha le-welding. Faka iifeni zokukhupha okanye izicoci zomoya ukugcina indawo yokusebenza ekhuselekileyo.
Sebenzisa izixhobo eziNcedisayo:
- Kwizixhobo zokusebenza ezineengubo ezishinyeneyo ze-zinc, qwalasela izixhobo zokufudumeza kwangaphambili ukunyusa ubushushu bendawo yokuwelda. Kungenjalo, jonga itekhnoloji yokuwelda ekumgangatho ophezulu njenge-laser welding ukuchaneka okuphezulu kunye nokusebenza kakuhle.
Isishwankathelo, iingubo ezityebileyo ze-zinc ziyabonyusa ubunzima be-welding phakathioomatshini bokuwelda indawo rhoqo. Nangona kunjalo, ngokuhlengahlengisa iiparamitha, ukukhetha ii-electrode ezifanelekileyo, ukuqinisekisa ukucoceka, ukuphucula umoya, kunye nokusebenzisa izixhobo ezincedisayo, le mingeni inokoyiswa ngempumelelo ukuze kuphunyezwe iiwelds ezikumgangatho ophezulu.
