Iziteshi Zensimbi Engagqwali H
Incazelo emfushane:
“Iziteshi zika-H” zibhekisela ezingxenyeni zesakhiwo ezimise njengohlamvu “H” ezivame ukusetshenziswa ekwakheni nasekusetshenzisweni kwesakhiwo okuhlukahlukene.
Iziteshi Zensimbi Engagqwali H:
Iziteshi zensimbi engagqwali H ziyizingxenye zesakhiwo ezibonakala ngesiphambano esimise okuka-H.Lezi ziteshi zakhiwe ngensimbi engagqwali, ingxubevange emelana nokugqwala eyaziwa ngokuhlala isikhathi eside, ukuhlanzeka, kanye nokukhanga kobuhle.Iziteshi zensimbi engagqwali H zithola izinhlelo zokusebenza ezimbonini ezihlukahlukene, okuhlanganisa ezokwakha, izakhiwo, nezokukhiqiza, lapho ukumelana nokugqwala kwazo namandla kuzenza zibe ukukhetha okuncanyelwayo kokusekelwa kwesakhiwo nokuklama.Lezi zingxenye zivame ukusetshenziswa ekwakhiweni kwezinhlaka, izisekelo, nokunye. izakhi zesakhiwo lapho kokubili amandla nokubukeka okupholishiwe kubalulekile.

Yiziphi izindlela zokushisela?
Izindlela zokushisela zihlanganisa i-arc welding, i-gas shielded welding (i-MIG/MAG welding), i-welding resistance, i-laser welding, i-plasma arc welding, i-friction stir welding, i-pressure welding, i-electron beam welding, njll. Indlela ngayinye inezinhlelo zokusebenza eziyingqayizivele nezici, ezifanele ezihlukahlukene. izinhlobo zezinto zokusebenza kanye nezidingo zokukhiqiza.I-arc isetshenziselwa ukukhiqiza amazinga okushisa aphezulu, ukuncibilikisa insimbi ebusweni bomsebenzi ukuze yakhe uxhumano.Izindlela zokushisela i-arc ezivamile zihlanganisa i-arc welding manual, i-argon arc welding, i-arc welding engaphansi kwamanzi, njll.Ukushisa okukhiqizwa ukumelana kusetshenziselwa ukuncibilikisa insimbi ebusweni bomsebenzi ukuze kwakhiwe uxhumano.I-Resistance welding ihlanganisa i-spot welding, i-seam welding kanye ne-bolt welding.
Yiziphi izinzuzo zokushisela i-arc engaphansi kwamanzi?
I-arc welding engaphansi kwamanzi ilungele ukuzishintshanisa nendawo enevolumu ephezulu.Ingakwazi ukuqedela inani elikhulu lomsebenzi wokushisela ngesikhathi esifushane futhi ithuthukise ukusebenza kahle kokukhiqiza.I-arc welding engaphansi kwamanzi ilungele ukuzishintshanisa nendawo enevolumu ephezulu.Ingakwazi ukuqedela inani elikhulu lomsebenzi wokushisela ngesikhathi esifushane futhi ithuthukise ukusebenza kahle kokukhiqiza.I-arc welding engaphansi kwamanzi ijwayele ukusetshenziselwa ukushisela amashidi ensimbi aminyene ngoba ukungena kwawo okuphezulu kwamanje nokuphezulu kuwenza asebenze kangcono kulezi zinhlelo zokusebenza.Njengoba i-weld imbozwe yi-flux, umoya-mpilo ungavinjelwa ngokuphumelelayo ukuthi ungangeni endaweni yokushisela, ngaleyo ndlela unciphise amathuba okuba ne-oxidation kanye ne-spatter.Uma kuqhathaniswa nezinye izindlela zokushisela okwenziwa ngesandla, ukushisela kwe-arc okungaphansi kwamanzi kungase kuzenzekele kalula, kunciphise izidingo eziphakeme amakhono abasebenzi.Ekushiseleni kwe-arc engaphansi kwamanzi, izintambo eziningi zokushisela nama-arcs zingasetshenziswa ngesikhathi esisodwa ukuze kuzuzwe ukushisela kweziteshi eziningi (izingqimba eziningi) nokuthuthukisa ukusebenza kahle.
Isingeniso somumo we-H beam ?
Umumo we-cross-sectional we-I-beam steel, ovame ukwaziwa ngokuthi "工字钢" (gōngzìgāng) ngesi-Chinese, ufana nohlamvu oluthi "H" uma luvulwa.Ngokucacile, isigaba esiphambene ngokuvamile siqukethe amabha amabili avundlile (ama-flange) phezulu naphansi kanye nebha emaphakathi eqondile (iwebhu).Lo mumo othi "H" unikeza amandla aphakeme nokuzinza kunsimbi ye-I-beam, okuyenza ibe into evamile yesakhiwo ekwakhiweni nasebunjiniyela.Umumo oklanyelwe we-I-beam steel uyivumela ukuthi ifanelekele izinhlelo zokusebenza ezihlukahlukene zokuthwala nokusekela, ezifana njengemishayo, amakholomu, nezakhiwo zebhuloho.Lokhu kumiswa kwesakhiwo kuvumela insimbi ye-I-beam ukuthi isabalalise ngempumelelo imithwalo uma ingaphansi kwamandla, ihlinzeka ngokusekelwa okuqinile.Ngenxa yokuma kwayo okuyingqayizivele nezici zesakhiwo, insimbi ye-I-beam ithola ukusetshenziswa kabanzi emkhakheni wokwakha nobunjiniyela.
Ungawuveza kanjani usayizi nenkulumo ye-I-beam?
H——Phezulu
B——Ububanzi
t1——Ukujiya kwewebhu
t2——Ubukhulu bepuleti le-Flange
h£——Usayizi wokushisela (uma usebenzisa inhlanganisela yezinqe nefillet, kufanele kube usayizi womlenze wokushisela oqinisiwe ongu-hk)
Ubukhulu, umumo kanye nokuchezuka okuvumelekile kwensimbi eshiselwe okumise okuka-H
Ubukhulu besigaba esiphambanayo, indawo ephambanayo, isisindo setiyori kanye nemingcele yesici eyisiphambano sensimbi eshiselwe okumise okuka-H
Amakhasimende ethu
Impendulo Evela Kubathengi Bethu
Iziteshi Zensimbi Engagqwali H ziyizingxenye zesakhiwo eziguquguqukayo ezakhiwe ngensimbi engagqwali yekhwalithi ephezulu.Lezi ziteshi zifaka umumo othi "H" ohlukile, onikeza amandla athuthukisiwe nokuzinza ezinhlelweni ezihlukahlukene zokwakha nezakhiwo.Isiphetho esihle nesiphucuziwe sensimbi engagqwali sinezela ukuthinta okuyinkimbinkimbi, okwenza lezi ziteshi ze-H zifanelekele kokubili izakhi zedizayini ezisebenzayo nezikhangayo. Umklamo omise okwe-H ukhulisa umthamo wokuthwala umthwalo, okwenza lezi ziteshi zibe zilungele ukusekela imithwalo esindayo ezindaweni zokwakha kanye nezimboni.Iziteshi ze-Stainless Steel H zithola izinhlelo zokusebenza ezimbonini ezihlukahlukene, ezihlanganisa ukwakhiwa, izakhiwo, nokukhiqiza, lapho ukusekelwa kwesakhiwo esiqinile kubalulekile.
Ukupakisha:
1. Ukupakisha kubaluleke kakhulu ikakhulukazi endabeni yokuthunyelwa kwamanye amazwe lapho impahla idlula eziteshini ezihlukahlukene ukuze ifike lapho kuyiwa khona, ngakho sibeka ukukhathazeka okukhethekile mayelana nokupakisha.
2. I-Saky Steel ipakisha izimpahla zethu ngezindlela eziningi ngokusekelwe emikhiqizweni.Sipakisha imikhiqizo yethu ngezindlela eziningi, njengokuthi,
