Intsimbi yegalvanized yimathiriyeli eyaziwayo ngepropathi yayo enganyangekiyo, nto leyo eyenza ukuba ibe lolona khetho lufanelekileyo kumashishini ahlukeneyo, kubandakanya ulwakhiwo, iimoto kunye nemveliso. E-Shandong Sino Steel Co., Ltd., sibonelela ngeekhoyili zentsimbi ezikumgangatho ophezulu kunye namaphepha ahlala ixesha elide kwaye asebenza ngeendlela ezahlukeneyo. Njengoko intsimbi ekhandisiweyo isiya isetyenziswa ngokubanzi kwizicelo zesakhiwo, umbuzo oqhelekileyo uvela: Ngaba isinyithi esinamatyholo sinokudityaniswa?
Ukuwelda intsimbi ekhandisiweyo kuzisa imingeni ekhethekileyo kwaye kufuna ubuchule obukhethekileyo. Kweli nqaku, siza kuphonononga inkqubo yokuwelda intsimbi, sigxininise amanyathelo okhuseleko, kwaye sichaze indlela yokufikelela kwi-welds ekumgangatho ophezulu ngelixa ugcina ukuxhathisa kwe-corrosion. Nokuba usebenza kunye amashiti entsimbi yokufulela okanye ukusebenzisa iikhoyili zentsimbi kumacandelo olwakhiwo, ukuqonda le migaqo kuya kuqinisekisa ukuba iiprojekthi zakho zigqitywe ngokukhuselekileyo nangempumelelo.
Ukuqonda imiceli mngeni yentsimbi kunye neWelding
I-Welding galvanized steel inokuba yinkohliso ngenxa ye-zinc coating ekhusela intsimbi ekudlekeni. Inkqubo ye-galvanization ibandakanya ukucwiliswa kwentsimbi kwi-zinc etyhidiweyo, ukudala umaleko we-zinc onika ukuxhathisa kokuhlwa kwexesha elide. Nangona kunjalo, xa usebenzisa ubushushu kule nto, i-zinc coating inokudala iingxaki.
Kwenzeka ntoni kwiZinc xa ishushu
I-Zinc ineqondo eliphantsi lokunyibilika xa lithelekiswa nentsimbi. Xa intsimbi ye-galvanized ibonakaliswe kubushushu ngexesha le-welding, i-coating ye-zinc iqala ukukhupha. Le nkqubo ikhupha umsi we-zinc oxide emoyeni. Le misi iyityhefu kwaye inokubangela imiba ebalulekileyo yempilo ukuba irholiwe. Kungenxa yoko le nto umoya ofanelekileyo kunye nokhuseleko lokuphefumla kubalulekile xa udityaniswa nentsimbi.
Ukongeza, ukufudumeza kwe-zinc kunokubangela ibhondi enqabileyo kwindawo edibeneyo. Oku kunokukhokelela kwiintanda okanye ubuthathaka kwi-weld, ukuphazamisa ukunyaniseka kwesakhiwo. Ke, ukuqonda indlela yokuziphatha kwe-zinc kumaqondo obushushu aphezulu kubalulekile kuye nabani na osebenza ngentsimbi.
IiNgxaki zoKhuseleko kuMsi kunye nokuPhumeza umoya
I-Welding galvanized steel ibandakanya ukukhutshwa komsi onobungozi, enye yezona zinto zibalulekileyo zokhuseleko. Umsi we-zinc oxide, oveliswa xa i-zinc yokwambathisa ingumphunga, inokukhokelela kwimeko eyaziwa ngokuba 'yi-metal fume fever' ukuba irholiwe. Iimpawu zefiva yentsimbi ziquka umkhuhlane, ukugodola, isicaphucaphu, kunye nokukhohlela, ezibangelwa yindlela umzimba osabela ngayo kumsi owuphefumlayo.
Ukunciphisa le mingcipheko, kubalulekile ukwenza i-welding kwiindawo ezinomoya owaneleyo. Ukuba i-welding i-welding endlini, iinkqubo zokukhupha umsi kufuneka zisetyenziswe ukususa umsi kwindawo yokusebenza. Ukongeza, abasebenzi kufuneka banxibe izixhobo zokuphefumla ukukhusela ekusezeleni umsi onetyhefu. I-PPE enjengeeglavu, iimpahla zokukhusela, kunye neendondo zokhuseleko kufuneka zinxitywe ukuzikhusela ekutshiseni nakwezinye iingozi ezinokubakho.
Iindlela zokuWelding ezigqwesileyo zeNtsimbi eGalisiweyo
Ukuwelda intsimbi yegalvanized kufuna ubuchule obukhethekileyo bokuqinisekisa ukuba iziphumo zokugqibela zomelele, zomelele kwaye zikhuselekile. Nokuba usebenzisa amashiti entsimbi yokugquma okanye iikhoyili zentsimbi ngeenjongo zokwakha, kukho iindlela ezininzi eziphambili ekufuneka uzilandele ukuqinisekisa iziphumo ezizezona zilungileyo.
Ukusila iZinc kwiNdawo yeWeld
Enye yezona ndlela zisebenzayo zokuthintela imiba ye-welding xa usebenza ngentsimbi ye-galvanized kukususa i-zinc coating ukusuka kwindawo ukuba ifakwe. Oku kunokwenziwa ngokugaya okanye ukugalela umphezulu ukuveza isiseko sesinyithi. Ngokususa i-zinc, unciphisa umngcipheko we-zinc vaporizing ngexesha le-welding, enceda ukuthintela ukubunjwa kwe-brittle welds.
Ukugaya i-zinc layer iphinda iqinisekise ukunamathela okungcono kwezinto zokuzalisa kwintsimbi, ukuphucula umgangatho opheleleyo we-weld. Le nkqubo ingenziwa ngokusebenzisa i-brush yocingo okanye i-grinder, kodwa kubalulekile ukuqinisekisa ukuba intsimbi ihlambulukile kwaye ikhululekile kuyo nayiphi na into engcolileyo ngaphambi kokuqala inkqubo ye-welding.
Iindlela zokuWelding ezicetyiswayo (MIG, TIG, SMAW)
Xa welding steel galvanized, indlela yokuwelda oyikhethayo ibaluleke kakhulu njengoko ulungiselela. Ezona ndlela zintathu zixhaphakileyo zokuwelda intsimbi yi-MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), kunye neSMAW (Shielded Metal Arc Welding). Indlela nganye ineenzuzo zayo kwaye ifanelekile kwizicelo ezahlukeneyo.

Ukuwelda phambi kweGalavanizing
Esinye sezona zigqibo zixhaphakileyo xa usebenza ngentsimbi ye-galvanized ukuba udibanise ngaphambi okanye emva kwenkqubo ye-galvanization. Zombini ezi ndlela zineengenelo zazo, kwaye ukuqonda lo mahluko ngundoqo ekufezekiseni iiwelds ezikumgangatho ophezulu.
Izinto eziluncedo kwiWelding kuqala
Ukuwelda intsimbi ekhandisiweyo phambi kokuba ingene kwinkqubo yokugalela ineenzuzo ezininzi. Xa i-welding phambi kwe-galvanizing, ususa iingxaki ezinokuthi zenzeke kwi-welding ngokusebenzisa i-zinc layer. Ngaphandle kwe-zinc, inkqubo ye-welding ilula, kwaye kukho umngcipheko oncitshisiweyo wokunciphisa amandla e-weld. Ukongeza, i-welding phambi kwe-galvanizing ivumela inkqubo yokucoca, elawulwa ngakumbi.
Nje ukuba i-welding igqitywe, intsimbi inokuthi ifakwe i-galvanized ukukhusela i-welds kunye neendawo ezijikelezileyo kwi-corrosion, iqinisekisa ukuhlala ixesha elide.
Iinketho zoKhuseleko lwePost-Weld
Ukuba i-welding yenzeke emva kokufakwa kwe-galvanization, kubalulekile ukuqinisekisa ukuba indawo edibeneyo ikhuselekile. Esinye isisombululo kukusebenzisa iikhompawundi ezibandayo zegalvanizing, eziziipeyinti ezityebileyo ze-zinc ezenzelwe ukulinganisa iimpawu zokukhusela ze-galvanization yediphu eshushu. Ezi peyinti zingasetyenziselwa kwiindawo ezidibeneyo ukuze zinikeze uluhlu olongezelelweyo lokukhusela.
Enye inketho kukubuyisela intsimbi emva kwe-welding. Oku kunokwenziwa ngokuthumela yonke inxalenye yentsimbi emva kwenkqubo yokufaka i-galvanizing ukuqinisekisa ukuba iindawo ezidibeneyo zifakwe ngokufanelekileyo kwaye zikhuselwe kwi-corrosion.
Ukhuseleko kunye neMilinganiselo yoKhuseleko
Ukuwelda intsimbi ekhandisiweyo kuza nemingcipheko yendalo, ngakumbi enxulumene nokuchanabeka kwimisi eyityhefu. Ukuqinisekisa amanyathelo afanelekileyo okhuseleko kunye nokusetyenziswa kwezixhobo ezifanelekileyo zokukhusela kubalulekile ukugcina indawo yokusebenza ekhuselekileyo.
I-PPE, iziPhumli kunye nokuPhumeza umoya
Njengayo nayiphi na inkqubo ye-welding, izixhobo zokukhusela zomntu (PPE) zibalulekile xa usebenza ngentsimbi. Oku kuquka iiglavu zokuwelda, iimpahla ezinemikhono emide, iindondo zokhuseleko, nesigcina-ntloko esikhuselayo kwimitha yelanga kunye neentlantsi ezibhabhayo. Kuba ukuwelda kwentsimbi ekhandisiweyo kukhupha umsi oyingozi, abasebenzi kufuneka banxibe izixhobo zokuphefumla ezenzelwe ukuhluza umsi we-zinc oxide.
Ukungena komoya okufanelekileyo kubaluleke ngokufanayo. Xa udityaniswa ngaphakathi endlwini, kubalulekile ukuba kubekho inkqubo yokungenisa umoya esebenzayo ukuqinisekisa ukuba umsi uyakhutshwa kwindawo yokusebenza. Ukuba kunokwenzeka, i-welding kufuneka yenziwe kwiindawo ezivulekileyo apho umoya omtsha unokunceda ukukhupha umsi.
Ukuphatha iZinc oxide Fumes
Umsi weZinc oxide yeyona nto iphambili xa udityaniswa nentsimbi. Lo msi unokuba yingozi xa utsaliwe, ngoko ke ukulawula ukungakhuseleki kubalulekile. Sebenzisa izixhobo zokutsala umsi ukubamba umsi kwindawo ekuvela kuyo umsi, okanye usebenze ngaphandle ukuba kunokwenzeka. Kwakhona kubalulekile ukunqanda ukuphefumla kwimiphunga ngokuthe ngqo, njengoko ukuvezwa ixesha elide kunokukhokelela kwimiba enzulu yokuphefumla.
