Ukuwelda bubuchule obubalulekileyo bokusebenza kwesinyithi obudibanisa amaqhekeza amabini esinyithi kwisakhiwo esinye esiqinileyo. Insimbi ye-galvanized yintsimbi efakwe kwi-zinc layer, enika ukhuseleko olongezelelweyo kwi-rust and corrosion. Nangona kunjalo, i-welding galvanized steel to steel inikezela imingeni ekhethekileyo ngenxa yeempawu zokugquma. Kweli nqaku, siza kuphonononga ukuba kuyenzeka na ukuwelda intsimbi ekhandiweyo ukuya kwintsimbi, imiceli mngeni onokuthi ujongane nayo, kunye nezona zenzo zilungileyo zokufumana intsimbi eyomeleleyo nehlala ixesha elide.
Nokuba usebenza kwiprojekthi yolwakhiwo, ukuveliswa kwemizi-mveliso, okanye iiprojekthi ze-DIY, ukuqonda inkqubo ye-welding yentsimbi eyenziwe ngamagalvanized ibalulekile ekuqinisekiseni imfezeko kunye nokhuseleko lweewelds zakho.
Yintoni intsimbi eyiGalvanized?
Ngaphambi kokungena kwi-welding, kubalulekile ukuqonda ukuba yintoni na intsimbi ekhandiweyo kwaye kutheni iziphatha ngokwahlukileyo kwintsimbi eqhelekileyo xa kufikwa kwi welding.
Insimbi eyenziwe nge-galvanized yenziwe ngokugubungela i-carbon steel kunye ne-zinc layer. Le nkqubo yokwenza igalvanizing yenziwa ukukhusela intsimbi kwirusi kunye ne-corrosion, ngokukodwa kwiindawo ezingaphandle okanye kwiindawo ezithanda ukufuma. Uluhlu lwe-zinc lusebenza njengesithintelo sokukhusela, ukuthintela insimbi kwi-oxidizing kunye nokwandisa ubomi bayo.
Nangona kunjalo, ubukho be-zinc bunokubangela imiba ngexesha le-welding. I-Zinc inendawo ephantsi yokunyibilika kunentsimbi, kwaye xa i-galvanized coating ifudunyezwa yinkqubo ye-welding, inokunyuka kwaye idale i-fumes enobungozi. Ukongezelela, i-zinc inokuchaphazela umgangatho we-weld ukuba ayiphathwa ngokuchanekileyo.
Ngaba ungayiwelda intsimbi yeGalvanized to Steel?
Ewe, kuyenzeka ukuwelda intsimbi ekhandiweyo ukuya kwintsimbi. Nangona kunjalo, inkqubo idinga ukunakekelwa okongeziweyo kunye nokulungiswa ngenxa yobukho bengubo ye-zinc. Imingeni ephambili yile:
I-Zinc Vaporization : Xa udibanisa intsimbi, i-zinc coating iya kuba ngumphunga ngenxa yobushushu obuvela kwinkqubo ye-welding. Oku kudala imisi eyityhefu, enokuba yingozi xa irholiwe. Amanyathelo afanelekileyo okungena komoya kunye nokhuseleko abalulekile ukuthintela ukuphefumla lo msi.
I-Weld Contamination : I-zinc engumphunga inokuxubana nentsimbi etyhidiweyo kwi-weld pool, ekhokelela kungcoliseko olunokwenzeka. Oku kunokuchaphazela umgangatho we-weld kwaye wenze kube buthathaka, okukhokelela kwimiba yesakhiwo kwimveliso egqityiweyo.
Umgangatho ombi we-Weld : I-Zinc inokubangela i-porosity, imeko apho imingxuma emincinci yenza i-weld bead, iyancipha i-weld. Ubukho be-zinc bunokukhokelela ekuqhekekeni okanye i-weld brittle, ukunciphisa amandla ayo onke.
Imiceli mngeni kwiWelding Steel Galvanized to Steel
Ngoku ukuba siyaqonda ukuba ukuwelda intsimbi yagalvanized kwintsimbi kunokwenzeka, makhe sixoxe ngemingeni ethile enxulumene nolu hlobo welding:
1. Umsi kunye nobutyhefu
Njengoko bekutshiwo ngaphambili, eyona nkxalabo iphambili xa udityaniswa nentsimbi ekhandisiweyo kukuveliswa komsi onetyhefu. Xa i-zinc itshisa ngexesha le-welding, ivelisa imiphunga ye-zinc oxide, eyingozi kwimpilo yabantu. Ukuba sesichengeni kulo msi ixesha elide kunokukhokelela kwifiva yentsimbi, imeko ebonakala ngeempawu ezinjengomkhuhlane ezifana nengqele, ifiva, kunye nesicaphucaphu. Ngenxa yesi sizathu, kubalulekile ukuqinisekisa ukungena komoya okufanelekileyo kwindawo yokuwelda.
Ukunciphisa umngcipheko wokuphefumla umsi we-zinc, soloko unxibe isiphefumlo esenzelwe ukusebenza kwesinyithi kwaye uqinisekise ukuba indawo yokusebenza ingena kakuhle. I-Welding kwindawo evulekileyo okanye ukusebenzisa inkqubo yokukhupha inokunciphisa kakhulu ingozi.
2. Pre-Welding Preparation
Ukuze ugweme imiba ebangelwe kukugquma kwe-zinc, amanye amanyathelo okulungiselela ayafuneka ngaphambi kokuba udityaniswe ngentsimbi enesinyithi:
Susa i-Zinc Coating : Enye yeendlela eziphumelelayo zokunciphisa iingxaki kukususa i-zinc coating ukusuka kwindawo apho i-weld iya kwenziwa khona. Oku kunokwenziwa ngokusebenzisa ibrashi yocingo, ivili lokusila, okanye izisombululo zekhemikhali ezilungiselelwe ngokukodwa ukuhluba i-zinc kwintsimbi. Ukususa i-coating kuthintela i-zinc ukuba ibe ngumphunga kwaye ingcolise i-weld.
Coca iNsimbi : Qinisekisa ukuba iindawo zentsimbi zicocekile kwaye azinamafutha, ioli, okanye inkunkuma. Ukucoca ngokufanelekileyo kuqinisekisa ukuba i-arc ye-welding inokudibanisa ngokufanelekileyo izinto ngaphandle kokuphazamiseka kwizinto ezingcolileyo.
3. Imiba ye-Post-Welding
Kwanasemva kokuwelda ngempumelelo intsimbi yagalvanized kwintsimbi, kungakho imingeni eyongezelelweyo ukujongana nayo:
Ii-Welds ezibuthathaka : Umgangatho we-weld unokuthi uphazamiseke ngenxa yomxholo we-zinc, ngakumbi ukuba awuzange ususwe ngaphambi kwe-welding. Emva kwe-welding, kubalulekile ukuhlola i-welds ukuze ubone naziphi na iimpawu zobuthathaka okanye iintanda.
I-Corrosion of Welded Area : Ngelixa intsalela yentsimbi ye-galvanized ikhuselwe kwi-rust nge-coating ye-zinc, intsimbi esanda kutshatyalaliswa kwindawo edibeneyo iyakwazi ukubola xa ingaphathwa kakuhle. Kubalulekile ukufaka isambatho esimelana nomhlwa kwindawo edityanisiweyo ukugcina ingqibelelo yesakhiwo.
Uyiwelda njani iNtsimbi eGalvanized kwiSimbi
Ukuba sele ulungele ukuwelda intsimbi ekhandisiweyo kwintsimbi, landela ezi ndlela zingcono zokunciphisa iingxaki kwaye uqinisekise intsimbi eyomeleleyo, ehlala ixesha elide:
1. Khetha iNkqubo yokuWelding eLungileyo
Eyona ndlela ifanelekileyo yokudibanisa insimbi ye-galvanized yi-MIG welding (i-Metal Inert Gas) kunye ne-TIG ye-welding (i-Tungsten Inert Gas). Ezi nkqubo zifaneleke ngcono kwiintsimbi ezinomlinganiselo obhityileyo njengentsimbi. Zombini iindlela zivumela i-welding echanekileyo kunye nokunciphisa umngcipheko wokutshisa okanye ukutshisa.
I-MIG Welding : Le ndlela isebenzisa intambo eyondliwe ngokuqhubekayo kwaye isoloko isetyenziselwa ukuwelda ngokukhawuleza. I-MIG welding ilungele izixhobo ezityebileyo kwaye inikezela ngolawulo olukhulu kwigalelo lobushushu.
I-TIG Welding : Le ndlela isebenzisa i-electrode ye-tungsten ukuvelisa i-weld ecocekileyo, echanekileyo. I-TIG welding iyacotha kodwa inika ulawulo olubalaseleyo kwi-weld, iyenza ilungele izicelo ezifuna ukuchaneka okuphezulu.
2. Sebenzisa iVentilation efanelekileyo kunye neGear yoKhuseleko
Njengoko bekutshiwo ngaphambili, ukuwelda intsimbi ekhandisiweyo kukhupha umsi onetyhefu. Ngalo lonke ixesha qinisekisa ukuba usebenza kwindawo enomoya owaneleyo, ngakumbi ngenkqubo yokukhupha umsi. Nxiba izixhobo ezifanelekileyo zokuzikhusela (i-PPE), kubandakanya isigcina-ntloko se-welding, iiglavu, kunye nesixhobo sokuphefumla. La manyathelo okhuseleko aya kunceda ukunciphisa umngcipheko wokuba sesichengeni somlilo onobungozi.
3. Susa i-Zinc Coating
Ukufezekisa iziphumo ezilungileyo, susa i-galvanized coating ukusuka kwindawo apho i-weld iya kwenziwa khona. Oku kunokwenziwa ngokusebenzisa ibrashi yocingo, izixhobo ezirhabaxa, okanye isisombululo sokuhlutha imichiza. Ngokususa i-coating, unciphisa umngcipheko wokungcola kwaye uqinisekise ukuba intsimbi engaphantsi kwe-zinc ibonakaliswe kwi-weld enamandla, ecocekileyo.
4. Lungisa i-Welding Parameters
Xa udibanisa intsimbi, yilumkele iparameters zakho zokuwelda, ezifana nombane, i-amperage, kunye nesantya. Ubushushu obuninzi bunokubangela ukuba i-zinc ibe ngumphunga kwaye idale i-weld engazinzanga. Qala ngezicwangciso ezisezantsi kwaye ulungelelanise njengoko kufuneka ukuphumeza i-weld egudileyo, ecocekileyo.
5. Ukucoceka kwePost-Welding kunye noKhuseleko
Emva kwe-welding, kubalulekile ukucoca indawo edibeneyo ukususa nayiphi na intsalela okanye i-oxidation enokuthi yenziwe ngexesha lenkqubo. Ukusebenzisa i-corrosion-resistant-resistant coating in the welded area kunceda ukukhusela kwi-rust, ukuqinisekisa ixesha elide lesakhiwo esidibeneyo.
Ukuqukumbela
Ukuqukumbela, ukuwelda intsimbi ekhandiweyo kwintsimbi kunokwenzeka, kodwa kufuna ukulungiswa okongeziweyo kunye nengqalelo kwiinkcukacha ngenxa yeempawu ezikhethekileyo zokwaleka. Ngokususa i-coating ye-zinc, usebenzisa indlela ye-welding efanelekileyo, kunye nokulandela iiprothokholi zokhuseleko, unokufezekisa i-weld ecocekileyo, ehlala ixesha elide. Nokuba usebenza kwizicelo zemizi-mveliso, iiprojekthi zokwakha, okanye uphuculo lwekhaya, ukuqonda indlela yokuwelda ngokufanelekileyo intsimbi ekhandiweyo kubalulekile ekuqinisekiseni impumelelo kunye nobomi obude beprojekthi yakho.
