Welding zethusi ekhaya

Ekwelapheni izinsimbi non-ayoni ngokuvamile kunzima, njengoba amazinga okushisa aphakeme izakhiwo zabo ngokomzimba ukushintsha. ukunakekelwa okukhethekile ufanelwe zethusi Welding, lapho kukhona asebenzayo zinc ukuhwamuka. Naphezu kobunzima babantu base nale ingxubevange kungenzeka ukusebenza endaweni yasekhaya.

Uhlelo oluyisisekelo oluthi izakhiwo impahla kanye nokulungiselela

Ngaphambi Welding zethusi ezocatshangelwa ngokuningiliziwe, kufanele kube ujwayelene izici impahla ngokwayo. Ukwakheka ingxubevange kuhlanganisa metal ezimbili base - zethusi ne-zinc. Okuqukethwe Owokugcina kubo ziyahlukahluka amaphesenti 5-45. It is yethulwa hhayi kuphela ukuthuthukisa izakhiwo ngokomzimba, kodwa futhi ukunciphisa izindleko emkhiqizweni ozophuma.

Brass wenze inani elikhulu imikhiqizo. Lezi zihlanganisa zonke izinhlobo plugs, adapters, ipayipi nezingxenye ezihlukahlukene zokuhlobisa. Ngo womshini zabo kungenziwa wanezela izakhi alloying kuthinte izici izinga:

• Tin angathuthukisa ukugqwala ukumelana ukusebenza:
• Aluminium ngezinga elithile kunciphisa simo esishubile zinc;
• Silicon kuthuthukisa weldability nge ukulahlekelwa elincane amandla;
• Ukuhola kwenza kube nokwenzeka ukuba athole okungenani umkhiqizo esiqinile lula handling ahlabayo indlela.

Ngenxa impahla eluhlaza for zokukhiqiza ingxubevange zethusi zinc kukhona preform, kanye nezinye izinsimbi ezithile. Kwezinye izimo, kungasetshenziswa imfucuza ukukhiqizwa yayo siqu. Ukuncibilika Kwenziwa qeda ukupholisa esebenzisa lokungeniswa amaziko.

Ubunzima ekusunguleni uxhumano unomphela

kahle futhi ngokuphepha kwethusi Welding ekhaya seliqediwe, odinga ukukwazi mayelana amaphuzu eziyinkinga. kwakwakhe Unsplit etholwe Ukushisa zendawo kuyoba okunokwethenjelwa kuphela ngaphansi izidingo ezikhethekile. Phakathi umsebenzi asikwazi bayakhohlwa izindlela zokuphepha, njengoba umphumela ezishisayo intuthu enobungozi esabiwe.

Inkinga eyinhloko itholakala burnup we-zinc esebenzayo, okuyinto lihlotshaniswa yayo ongaphakeme ukuma (ka 419 degrees). Iningi izinto emsebenzini iphele. Ngenxa yalokho, ezinye ingxenye engena zihlangana nomoya-mpilo, ukwakha powder emhlophe okuyinto kamuva ayeseshumayele ezindaweni eduze umphetho.

Okumele kuqashelwe ngesikhathi handling

Self-Welding zethusi akufanele kuholele kumiswa izimo eziyingozi mayelana nomzimba womuntu. Ngenxa sithuthukiswe ukukhululwa umsebenzi compounds oluyingozi kumele isetshenziswe lapho besebenza respirators. Ngisho uma usebenzisa amasu ezikhethekile nokutubeka zinc amabanga kusuka 25 kuya kumaphesenti angu-30.

Akuvunyelwe ukuba bafeze imisebenzi Welding eduze izinto futhi izinto, oluvuthayo ngokushesha. Eduze emsebenzini kufanele kube kungekho fuel, ukhuni shavings, Hemp noma igesi amasilinda. Isimo eyisibopho ingaphansi khona umoya egumbini.

Amalungiselelo izakhi

Lapho Welding wenziwa zethusi ukujiya encane, ukwenza pre-Ukushisa akudingekile. Lapho elibona nxazonke izakhi omkhulu Kunconywa ukuba ukwelashwa ukushisa wendawo. ukulungiselela Edge engenziwa ukuze umkhiqizo ukushuba 1.5-6 mm.

Uma makhemikhali kwesigaba enkulu esiphambanweni, noma kunjalo, udinga ezimise-V ahlabayo sutures. Kuyinto elula, kodwa engeyinhle. Kungcono ukuba bafeze X emise uhlinza lapho engela ukuvulwa kuyinto 30-45 degrees ohlangothini ngalunye.

Izinhlobo kanye nobuchwepheshe osetshenziswayo ukuqhathanisa

Ezimweni eziningi, wenza zethusi Welding nge argon. Ubuchwepheshe izingxenye kwakwakhe isimo inert kubhekwa ethembisayo, ngoba ivumela ukuba ingafinyelela isivinini eliphezulu lomsebenzi. Phakathi kwezinye izinzuzo le ndlela kufanele ezigqanyisiwe:

• kungenzeka ukuthola ezinkulu nge-geometry ecacile futhi bahlanzeke ngokwenkolo;
• homogeneity we isakhiwo emkhakheni uxhumano unomphela;
• nokwethenjelwa amalunga;
• kahle ngenxa ukusetshenziswa engabizi tungsten electrode.

Enye nqubo igesi Welding. Akukona ezihilela ukusetshenziswa umthombo wamandla kagesi, okuyinto ulungisiswa kwezinye izimo. Ngo isicelo yayo kungenzeka etinhlotjeni letibanti ngokwanele ububanzi ukulawula amandla kokuphuma ilangabi. Nge Ukukhetha efanele zokushisela okudlekayo ekhiqizwa eliphezulu welds.

Argon Welding zethusi: inqubo incazelo

ULwesithathu igesi avikele inikeza ithuba nokunciphisa imiphumela emibi embalwa. Welding zethusi nethusi kule samuntu, wenabisela nge zamanje njalo kokuba polarity ngqo. Ngenxa awokuthi wokusha Kunconywa ukuba aphathe isikhundla docking ngumuntu arc eside.

I electrode ufakwa ithoshi, okuyinto indlela conductive. Ngemva kwalokho, lo inkinobho iyunithi. Ukusebenza ephelezelwa ufa anda, okubonakala ngenxa kwezulu ngentukuthelo zinc. I wire yamathebhu is busuka ngokuhlanganyela ngesandla.

Ngokuvamile hlanganisa ezinamasondo ngabanye, kunemikhiqizo ukupheka ubuchwepheshe okuqhubekayo. Lapho ukushumeka wentaba, kuyinto efiselekayo kancane ukunciphisa yamandla aphindeke kabili ye-arc. Ngesikhathi esigabeni sokugcina kubalulekile ukususa ohlangothini. Voltage yokusebenza kumele encishisiwe ngokushesha, kodwa kancane kancane.

Ukusetshenziswa imishini igesi

Ezindaweni nge engekho kagesi umthombo arc ubuchwepheshe ayikwazi ukusetshenziswa. Nokho, kulesi simo, kuvunyelwe igesi Welding ngethusi. Nokho, ukusebenzisa kwayo kwakwakhe okuqinile etholakala, kuyadingeka ukusebenza izinto ngempela eziyingozi, okuyinto kanye oxygen ukuze kwakheke ama Izingxube kuqhume.

Lapho besebenza ukugwema ukuhwamuka ngokweqile zinc kungaba ngokusebenzisa oxidizing sikaphalafini ilangabi zokusebenza. Oxygen kumelwe sibe sikhulu kakhulu kunalokho hydrogen. Lapho ekucubunguleni esibonakalayo ibonakala ifilimu ebusweni oxide ivumela ngezinga elithile ukuvikela indawo kusukela zinc KULETHA.

Lapho Welding yamathebhu wire kufanele ibekwe i-engela 15 kuya ku-30 degrees emaphethelweni ohlangothini. Gwema kunyakaza transverse ukuqaliswa ukusebenza. Sikaphalafini kumele kube i-engela degrees 70 kuya ku-80 ukuba workpiece.

Filler impahla ibekwe ngaphezu kwe-okugeza oncibilikisiwe ngqo ilangabi sikaphalafini. Ungacwilisi induku elisetshenziswa ingaphakathi umphetho. Lapho mhubhe kuyinto efiselekayo banamathele isivinini ethile. Ngokuvamile kuba 15-25 cm ngomzuzu.

Uma exhunywe kwi-workpiece ukujiya elikhulu, kufanele ibekwe i-engela degrees 10 kuya ku-15 kuya ovundlile. Zokushisela is wabe eseya lapho kuyanda. Ngokuvamile, uphahla amalunga Kulokhu zinganeliswa, kusukela okokusebenza flowable.

Welding nezinye izinsimbi kanye Alloys

Ngesinye isikhathi kuyadingeka ukuxhuma zethusi nezinye izinto ezingafani. Kulokhu, udinga ukwazi ngezici imisebenzi enjalo. Lapho kuhlangene steel ezingavela obuthile, ngenxa ezahlukene physico-chemical izici Alloys ezimbili.

A isici ezivamile Welding Akukhona ukubukeka imifantu steel ebusweni ngokuqondile ngaphansi ungqimba zethusi. kunconywa ukusebenzisa ingxubevange nickel ukuze kuncishiswe ingozi lezi zamehlo. Kuhle argon amasu kusetshenziswa electrode tungsten.

Inhlanganisela titanium nge Alloys zethusi kungaholela ekwakhekeni izibopho zamakhemikhali ziyaqothuka. Umthelela engcono kuba yipumelelo lokha usebenzisa ifaka Lesisemkhatsini. Zenziwa titanium ingxubevange, doped nge niobium noma molybdenum. Kwezinye izimo, avunyelwe ukusebenzisa inhlanganisela Alloys.

Izakhiwo niobium lungaphezu efana titanium, ngakho-ke ngokugculisayo ashiselwe kuya ngethusi. Nokho, lo msebenzi kumele kwenziwe isimo inert. amakhamera akhethekile avame ukusetshenziswa, lapho umoya ilawulwa ngokuphelele.

Yokugcina ingxenye

Kufanele kuqashelwe ukuthi ubuchwepheshe zethusi Welding has izici zayo siqu okumelwe icatshangelwe uma udala uxhumano unomphela ekhaya ngaphandle ukubandakanywa Ochwepheshe. Ekuhloleni yonke imininingwane yenqubo kungenzeka ukufeza ephephile uxhumano izikhala. Ngokuphathelene kukhethwa indlela, kuba wancika ngokwengeziwe khona hardware kanye namasistimu okusebenza izimo ezithile.
