Intsimbi umbhobhouphuhliso lobuchwephesha bokuvelisa lwaqala ngokunyuka kwemveliso yebhayisekile, uphuhliso lweoyile ekuqaleni kwenkulungwane ye-19, iinqanawa ezimbini zeemfazwe zehlabathi, iibhoyila, ukwenziwa kweenqwelomoya, emva kwemfazwe yesibini yokuvelisa ibhoyila yamandla ashushu, ishishini kwaye ke ngoko uphuhliso lweoyile negesi yokomba kunye ukuthuthwa, ukuqhuba ngokufanelekileyo ishishini lombhobho wensimbi ngaphakathi kophuhliso lweentlobo, isivuno kunye nomgangatho. Ngokuqhelekileyo umbhobho wentsimbi ngokuhambelana nendlela yokuhlanganisa, yahlulwe yaba ngumbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi odityanisiweyo iindidi ezimbini, ngoku ubukhulu becala ukwazisa umbhobho wentsimbi odityanisiweyo.
Umbhobho wentsimbi odityanisiweyo kukuba umbhobho wentsimbi edityanisiweyo, imveliso yayo kukuba umbhobho ongenanto (ipleyiti yentsimbi kunye nebhanti yentsimbi) kunye nokusasazwa kweendlela zokubumba ukugoba kunye nokuqengqeleka kwimilo enqwenelekayo yecandelo kunye nobungakanani betyhubhu, kwaye sebenzisa iindlela ezahlukeneyo ze-welding ukuze udibanise i-weld kwaye ufumane inkqubo yombhobho wentsimbi. Xa kuthelekiswa nombhobho wentsimbi engenamthungo, umbhobho odityanisiweyo uneempawu zokuchaneka okuphezulu, ngakumbi ukuchaneka kobukhulu bodonga, izixhobo eziphambili ezilula, umsebenzi omncinci, ukusebenza okuqhubekayo kwimveliso, imveliso eguquguqukayo, uluhlu olubanzi lwemveliso yeyunithi ngoko.
Inkqubo yokwenziwa kwemibhobho iya kwahlulwa ibe: SSAW (Spirally Submerged Arc Welding); I-LSAW (i-Longitudinous Arc Welding); ukuxhathisa kombane Ukuwelda (ERW) ezintathu.
I. inkqubo yokuhlanganisa umbhobho wentsimbi ejikelezayo imalunga noku kulandelayo
● Imathiriyeli ekrwada yombhobho wentsimbi ejikelezayo yi-strip coil, i-welding wire kunye ne-flux.
● Ngaphambi kokwenza umcu emva kokulinganisa, ukusika, ukucwangcisa, ukucocwa komphezulu, ukuthuthwa kunye nokugoba.
● Isixhobo sokulawula umsantsa weld siqeshwe ukuqinisekisa ukuba umsantsa weld uyahlangabezana neemfuno ukuwelda, kwaye kwakhona ububanzi umbhobho, edge edge kunye umsantsa weld zilawulwa ngokungqongqo.
● Emva kokugawula kumbhobho wentsimbi enye, ibhetshi nganye yentloko yombhobho wentsimbi emithathu ukubamba inkqubo yokuhlola engqongqo kuqala, jonga iipropati zomatshini we-weld, ukwakheka kweekhemikhali, imeko yokunyibilika, umgangatho wombhobho wentsimbi kwaye emva kokuhlolwa okungonakalisi, qiniseka ukuba umbhobho. ukwenza inkqubo ifaneleke, ifakwa ngokusesikweni kwimveliso.
Emibini, ethe tye i-arc welding pipe
Umthungo othe tye wantywiliselwa umbhobho wearc odityanisiweyo (LSAW) uthatha ipleyiti njengesixhobo, ngokwenkqubo eyahlukeneyo yokubumba, wamkela ukuwelda kwearc enamacala amabini kunye nokwandiswa kwe-post-welding kunye nezinye iinkqubo zokwenza umbhobho odityanisiweyo.
Esona sixhobo siphambili kukubumba umatshini, umatshini wokugoba ngaphambili, umatshini wokwenza, umatshini wokuwelda ngaphambili, umatshini wokwandisa emva koko. Okwangoku, kukho i-UO (UOE), i-RB (RBE), i-JCO (JCOE) kwaye emva koko. Ipleyiti ngaphakathi kokubumba ukubumba kuqala icinezelwe ibe imilo U, ngoko icinezelwe kwi O imilo, kwaye ke ingaphakathi kunye nangaphandle entywiliselwe arc welding, welding ngokuqhelekileyo phezulu okanye ubude obupheleleyo Ukwandiswa (Ukwandisa) ebizwa UOE welded umbhobho, hayi. Ukwandisa ebizwa UO welded umbhobho. Ipleyiti iqengqeleke Ukugoba imilo, emva koko i-arc ye-arc yangaphakathi kunye ne-welding yangaphandle ifakwe emanzini. Emva kwe-welding, i-diameter yityhubhu edityanisiweyo ye-RBE okanye ityhubhu edityanisiweyo ye-RB ngaphandle kokwandisa. Ipleyiti idalwe ngaphakathi komyalelo we-JcO-uhlobo, kwaye emva kwe-welding, ububanzi buyanda kwi-JCOE umbhobho odibeneyo okanye umbhobho we-JCO odibeneyo ngaphandle kokwandisa.
Ezintathu, umthungo othe tye umbhobho we-welded welded (ERW) kukuba i-coil eshushu eqengqelekayo emva komatshini wokubumba, usebenzisa into yombane kunye nefuthe elisondele kwi-high frequency yangoku, ngoko ke ukuhlaba kombhobho kuyafudunyezwa kwaye kunyibilike, phantsi kwesenzo se-extrusion. welding yoxinzelelo lwe-roller ukufikelela kwimveliso.
