Ukwenziwa kwemihla yentsimbi yentsimbi ukusuka ekuqaleni kweminyaka yee-1800. Ekuqaleni, imibhobho yenziwa ngesandla - ngokufudumeza, ukugqobhoza, imbeke, kunye nokuphuphuma kwemiphetho kunye. Inkqubo yokuqala yokuvelisa i-Pipe ezenzekelayo yaziswa ngo-1812 eNgilani. Iinkqubo zeMveliso ziphucule ukususela ngeloxesha. Ezinye iindlela zokwenza umbhobho odumileyo zichazwe ngezantsi.
I-WOLD YONYAKA
Ukusetyenziswa kwe-Ilding ye-Ilding ukwenza umbhobho wawaziswa ekuqaleni kweminyaka yee-1920. Nangona le ndlela ayisasebenzi, umbhobho othile owenziwe usebenzisa inkqubo ye-Welding ye-UWelding isasebenza namhlanje.
Kwinkqubo ye-welding ye-welding, intsimbi yafuduswa kwiziko kwaye emva koko yaqengqeleka kwimo ye-cylinder. Imiphetho yentsimbi yensimbi yayikukuphela "" Ukucofa kubandakanya ukutyhoboza umphetho wensimbi, kunye nomphetho ojikelezayo kwelinye icala leplate. Umthungo ke wawudla ngokusebenzisa ibhola ye-welding, kwaye umbhobho oshushu wadluliswa phakathi kweengqengqelo ezinyanzela umthungo.
Ii-wels eziveliswa zii-welling ze-welding azithembekanga njengoko zidalwe zisebenzisa iindlela ezininzi zanamhlanje. Uluntu lwaseMelika lweenjineli zoomatshini (i-ASME) sele iphuhlise i-equation ukuba ivunyelwe ukuba ivunyelwe ngoxinzelelo oluvumelekileyo lombhobho, ngokusekwe kuhlobo lwenkqubo yokwenziwa. Le nxaki ibandakanya ukwahluka okwaziwa ngokuba "yinto edibeneyo", isekwe kuhlobo lwe-weld esetyenziselwa ukwenza umngxunya wombhobho. Imibhobho ye-wamp inombhobho odibeneyo we-1.0 yombhobho weflding ye-Welding enento edibeneyo ye-0.6.
Ukuchasana kombane
Umbhobho wombane we-Weldied (Erw) wenziwa ngumbhobho obandayo wentsimbi kwi-cylindrical ses. Okwangoku emva koko idluliselwe phakathi kwemiphetho emibini yentsimbi ukuba itshise intsimbi ukuya kwinqaku apho imiphetho inyanzelwa khona ukwenza ibhondi ngaphandle kokusetyenziswa kwe-filler filler. Ekuqaleni le nkqubo yokwenziwa isebenzise i-free frequency ac yangoku yokutshisa imiphetho. Le nkqubo ye-frequency ephantsi yasetyenziswa ukusuka kwiminyaka yoo-1920 de kwangowe-1970, inkqubo ye-frequency ephantsi yayithathwa yinkqubo ephezulu ye-supw evelise umgangatho ophezulu.
Ngokuhamba kwexesha, ii-wels ze-pume ephantsi ejikelezayo zafunyanwa zichaphazeleka ekuthatheni i-seam yokukhetha i-seam, i-hook, kwaye ingonelanga ye-SEAMS, i-EARCE YORRECY SANDS engasasebenziyo ukwenza umbhobho. Inkqubo ye-frequency isenziwa ukuba isetyenziselwe ukwenza umbhobho wokusetyenziswa kwi-Pipelit entsha yePipelit.
Umbhobho wombane wefleshi
Umbhobho wombane wefleshi wenziwe nge-1927. I-Flash Idling yaphunyezwa ngokuqulunqwa kwephepha lensimbi. Imiphetho yafuduswa ide ifikelele e-semi-molten, emva koko yanyanzeliswa de kwanyanzelwa intsimbi edibeneyo kwihlazo kwaye yakha intsholongwane. Njengombhobho wamanzi ophantsi we-frewuncy, imitha yombhobho we-Wlash ye-Welding ichaphazeleka kukungabikho, kodwa ukuya kwinqanaba elincinci kunomgangatho we-erw. Olu hlobo lombhobho kukwasengozini yokusilela ngenxa yamabala anzima kwiplati yeplate. Kungenxa yokuba uninzi lombhobho we-welding we-flash waveliswa ngumenzi omnye, kuyakholelwa ukuba la machaphaza anzima ezenzeka ngenxa yokucinywa kwentsimbi ngexesha lenkqubo yokwenziwa kwayo. I-flash yelding ayisasebenzi ukwenza umbhobho.
I-arc engaphantsi ye-arc ye-welc ye-welc (i-DSAW) yombhobho
Ifana nezinye iinkqubo zokwenza umbhobho, ukwenziwa kombhobho we-arc owenziweyo ophakathi kubandakanya ukwenza iipleyiti zentsimbi kwimilo ye-cylindricrical. Imiphetho yeplate eqengqelwe yenziwa ukuze i-grooves ene-v-vales yenziwa ngaphakathi nangaphandle kwindawo yendawo yomthungo. Umthungo we-pump uqengqeleka ngepady ye-arc ye-arc ye-arc kwindawo engaphakathi nangaphandle (ngenxa yoko) kabini). I-welding Arc iphantsi kwe-gubile.
Inzuzo yale nkqubo kukuba i-wellos ingena kwi-100% yodonga lombhobho kwaye ivelise ulwalamano olunamandla kakhulu lwezinto zombhobho.
Umbhobho ongenamthungo
Kwenziwe umbhobho wefestile ukusukela kwiminyaka yoo-1800. Ngelixa inkqubo ivele, izinto ezithile zihlala zinjalo. Umbhobho ongenamthungo wenziwa ngokubhoboza i-billle yentsimbi eshushu nge-mandrel. Intsimbi ebiyelweyo ingaphezulu kwentambo kwaye yolulekile ukufezekisa ubude obufunayo kunye nobubanzi. Eyona nto iphambili kumbhobho ongenamthungo kukupheliswa kweziphene ezinxulumene nedolophu; Nangona kunjalo, iindleko zemveliso zinkulu.
Umbhobho wokuqala ongenamthungo wawusengozini kwiziphene ezibangelwa kukungcola kwintsimbi. Njengoko iindlela zokwenza inyikizi ziphucule, ezi ziphene zancitshiswa, kodwa azipheliswa ngokupheleleyo. Ngelixa kubonakala ngathi umbhobho ongenamthungo uya kukhethwa ukuba kwenziwe umbhobho we-WEAM-WelD, amandla okuphucula iimpawu ezinqwenelekayo kumbhobho. Ngesi sizathu, umbhobho ongenamthungo ngoku ukhona kumaBanga asezantsi kunye nodonga lodonga kunokwenza umbhobho we-welding.
Iqela le-Jindalai Iqela likhethekileyo ekuveliseni isiza se-tee-Tech (indalo yombane) kunye ne-SSAW Inkampani yethu ihamba phambili φ610 mm-up-free-freenchentency ye-selding ye-Wolding ye-Wolding, kunye ne-φ3048mm spined spiral. Ngokunjalo, ngaphandle kwe-erw kunye neefekfi ze-SSAW, sinezinye iifektri ezintathu ezihambelanayo ze-lsaw kunye nemveliso ye-SML kuyo yonke iChina.
