Umbhobho wentsimbi edibeneyo: Isikhokelo esipheleleyo sokuqinisekisa uqhagamshelo olusebenzayo noluthembekileyo

Yazisa:

Kuwo onke amashishini, iipayipi zentsimbi zisetyenziswa kakhulu ngenxa yokuqina kwazo, ukuqina kwazo, kunye nokuguquguquka kwazo. Xa udibanisa iipayipi zentsimbi, ukuwelda yindlela ekhethwayo. Ukuwelda kudala unxibelelwano oluqinileyo olunokumelana noxinzelelo oluphezulu, okwenza kube yinto ebalulekileyo kumacandelo afana nokwakha, ioyile negesi, kunye nokuvelisa. Kule bhlog, siza kufunda ukubaluleka kokuwelda iipayipi zentsimbi kwaye sinike isikhokelo esibanzi sokuqinisekisa unxibelelwano olusebenzayo noluthembekileyo.

Ipropati yoomatshini

Ukwenziwa kweeKhemikhali

Uvavanyo lwe-Hydrostatic

Ubude bombhobho ngamnye buya kuvavanywa ngumvelisi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungaphantsi kwama-60% wamandla aphantsi okuvelisa kubushushu begumbi. Uxinzelelo luya kugqitywa yile equation ilandelayo:
P=2St/D

Utshintsho Oluvumelekileyo Kubunzima Nobukhulu

Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bawo obuqikelelwayo, obubalwe kusetyenziswa ubude bawo kunye nobunzima bawo ngobude beyunithi nganye.
Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle.
Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% ​​phantsi kobukhulu bodonga obuchaziweyo.

Ubude

Ubude obungacwangciswanga obunye: 16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
Ubude obuphindwe kabini obungacwangciswanga: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude obufanayo: umahluko ovumelekileyo ±1in

Iphela

Iipayipu mazifakelwe iziphelo ezingenanto, kwaye iziphelo ezisemaphethelweni mazisuswe.
Xa isiphelo sepayipi esichazwe njengesiphelo se-bevel, i-engile mayibe ngama-30 ukuya kuma-35 degrees

1. Qonda imibhobho yentsimbi:

 Iipayipi zentsimbiziza ngobukhulu obahlukeneyo, iimilo kunye nezixhobo, nganye ifanelekile kwizicelo ezithile. Zihlala zenziwe ngentsimbi yekhabhoni, intsimbi engatyiwayo okanye intsimbi ye-alloy. Iipayipi zentsimbi yekhabhoni zisetyenziswa kakhulu ngenxa yokuba zifikeleleka kwaye zinamandla, ngelixa iipayipi zentsimbi engatyiwayo zibonelela ngokumelana nokugqwala okugqwesileyo. Kwiimeko zobushushu obuphezulu, iipayipi zentsimbi ye-alloy ziyathandwa. Ukuqonda iintlobo ezahlukeneyo zeepayipi zentsimbi kuya kunceda ekuchongeni ukhetho olufanelekileyo lokuwelda.

2. Khetha inkqubo yokuwelda:

Kukho iintlobo ngeentlobo zeenkqubo zokuwelda ezisetyenziselwa ukudibanisa imibhobho yentsimbi, kuquka ukuwelda kwe-arc, ukuwelda kwe-TIG (tungsten inert gas), ukuwelda kwe-MIG (metal inert gas), kunye nokuwelda kwe-arc engaphantsi komhlaba. Ukukhetha inkqubo yokuwelda kuxhomekeke kwizinto ezifana nohlobo lwentsimbi, ububanzi bombhobho, indawo yokuwelda kunye noyilo lwamalungu. Indlela nganye inezibonelelo kunye nemida yayo, ngoko ke ukukhetha inkqubo efanelekileyo kwisicelo esifunekayo kubalulekile.

3. Lungisa umbhobho wentsimbi:

Ukulungiswa kakuhle kwemibhobho ngaphambi kokuyidibanisa kubalulekile ekufezekiseni ijoyinti eqinileyo nethembekileyo. Kubandakanya ukucoca umphezulu wombhobho ukususa naluphi na ugqwala, isikali okanye izinto ezingcolisayo. Oku kungenziwa ngeendlela zokucoca ngoomatshini ezifana nokuxubha ucingo okanye ukugawula, okanye ngokusebenzisa izicoci zeekhemikhali. Ukongeza, ukuxubha isiphelo sombhobho kudala umngxuma onobume obungu-V ovumela ukungena ngcono kwezinto zokuzalisa, ngaloo ndlela kube lula inkqubo yokuyidibanisa.

4. Itekhnoloji yokuwelda:

Indlela yokuthunga esetyenzisiweyo ichaphazela kakhulu umgangatho wejoyinti. Ngokuxhomekeke kwinkqubo yokuthunga esetyenzisiweyo, iiparameter ezifanelekileyo ezifana nomsinga wokuthunga, i-voltage, isantya sokuhamba kunye nokufakwa kobushushu kufuneka zigcinwe. Izakhono namava omthungi nazo zidlala indima ebalulekileyo ekufezekiseni i-weld elungileyo nengenaziphene. Iindlela ezifana nokusebenza ngokufanelekileyo kwe-electrode, ukugcina i-arc ezinzileyo, kunye nokuqinisekisa ukuhamba kwegesi okukhuselayo ngokwaneleyo kunokunceda ukunciphisa iziphene ezifana nokuqhekeka okanye ukungabikho kokudibana.

5. Ukuhlolwa emva kokuwelda:

Nje ukuba ukuwelda kugqityiwe, kubalulekile ukwenza uhlolo emva kokuwelda ukuze kufunyanwe naziphi na iziphene okanye iziphene ezinokuthi zonakalise ukuthembeka kwelungu. Iindlela zovavanyo ezingonakalisiyo ezifana nokuhlolwa ngokubona, uvavanyo lokungena kwedayi, uvavanyo lwe-magnetic particle okanye uvavanyo lwe-ultrasound zingasetyenziswa. Olu hlolo lunceda ekuchongeni iingxaki ezinokubakho kwaye luqinisekise ukuba amalungu aweldayo ayahlangabezana neemfuno ezifunekayo.

Ukuququmbela:

 Umbhobho wentsimbi wokuweldaifuna ukuqwalaselwa ngononophelo kunye nokusebenza ngokuchanekileyo ukuqinisekisa uqhagamshelo olusebenzayo noluthembekileyo. Ngokuqonda iintlobo ezahlukeneyo zemibhobho yentsimbi, ukukhetha inkqubo efanelekileyo yokuwelda, ukulungiselela ngokupheleleyo umbhobho, ukusebenzisa iindlela ezifanelekileyo zokuwelda, kunye nokwenza uhlolo lwasemva kokuwelda, ungafikelela kwii-welds eziqinileyo nezisemgangathweni ophezulu. Oku kunceda ukuphucula ukhuseleko, ukuthembeka kunye nobomi benkonzo yemibhobho yentsimbi kwizicelo ezahlukeneyo apho zizinto ezibalulekileyo.
