Umbhobho wentsimbi we-ERW
Umbhobho we-ERW (umbhobho odibeneyo oxhathisayo ngombane) kunye nombhobho we-CDW (umbhobho odibeneyo otsalwe ngokubandayo) ziinkqubo ezimbini ezahlukeneyo zemveliso yemibhobho yentsimbi edibeneyo.
1. Inkqubo yemveliso
| Izinto zokuthelekisa | Umbhobho we-ERW (umbhobho odibeneyo wokuxhathisa umbane) | Umbhobho we-CDW (umbhobho odibeneyo otsalwe ngokubandayo) |
| Igama eliphelele | Umbhobho oWelding we-Resistance Electric | Umbhobho odibeneyo otsalwe ngendlela ebandayo |
| Inkqubo yokwenza | Umphetho wepleyiti yentsimbi ufudunyezwa ngumbane ophindaphindayo kwaye ucinezelwe kwaye welded ukuze ube yimo | Kuqala kudityaniswe kwiipayipi, emva koko kutsalwe kubanda (unyango lokuguqulwa kwesikhunta kubanda) |
| Indlela yokuwelda | Ukuwelda okuxhathisa ukuphindaphinda okuphezulu (HFW/ERW) | I-ERW okanye i-argon arc welding (TIG) idla ngokusetyenziselwa ukuwelda |
| Ukucubungula okulandelayo | Ukulinganisa kunye nokusika ngokuthe ngqo emva kokuwelda | Ukugqiba umzobo obandayo (ukuqengqeleka okubandayo) emva kokuwelda |
2. Iimpawu zokusebenza
Umbhobho we-ERW
Ukuchaneka kobukhulu: Jikelele (± 0.5% ~ 1% ukunyamezelana kobubanzi bangaphandle)
Umgangatho womphezulu: I-weld icacile kancinci kwaye kufuneka ipholishwe
Iimpawu zoomatshini: Amandla axhomekeke kwizinto eziyintloko, kwaye kusenokubakho ukuthamba kwindawo yokuwelda
Uxinzelelo oluseleyo: Luphantsi (unyango olulula lobushushu emva kokuwelda)
Umbhobho weCDW
Ukuchaneka kobukhulu: phezulu kakhulu (ngaphakathi kwe-±0.1mm, kufanelekile ngeenjongo zokuchaneka)
Umgangatho womphezulu: umphezulu ogudileyo, akukho nqanaba le-oxide (elikhazimlisiweyo emva komzobo obandayo)
Iipropati zoomatshini: ukuqina kokusebenza ngokubanda, amandla anyuswe ngama-20% ~ 30%
Uxinzelelo olushiyekileyo: luphezulu (kufuneka ukutsalwa kwe-annealing ukuze kupheliswe uxinzelelo lokutsalwa ngumoya obandayo)
3. Iimeko zesicelo
I-ERW: imibhobho yeoyile/igesi, imibhobho yesakhiwo (i-scaffolding), imibhobho yolwelo oluphantsi koxinzelelo (GB/T 3091)
I-CDW: ii-hydraulic cylinders, iindawo ezichanekileyo zoomatshini (ezifana nemikhono yokuthwala), ii-automobile transmission shafts (iindawo ezineemfuno zokuchaneka okuphezulu)
Imigangatho eqhelekileyo yeentlobo
I-ERW: I-API 5L (umbhobho wepayipi), i-ASTM A53 (umbhobho wesakhiwo), i-EN 10219 (umbhobho we-welded oqhelekileyo waseYurophu)
I-CDW: I-ASTM A519 (umbhobho otsalwa ngokucokisekileyo obandayo), i-DIN 2391 (umbhobho osemgangathweni waseJamani ochanekileyo kakhulu)
Umbhobho we-CDW = umbhobho we-ERW + umzobo obandayo, onobukhulu obuchanekileyo kunye namandla aphezulu, kodwa kunye neendleko eziphezulu.
Umbhobho we-ERW ufanelekile kwiinjongo zesakhiwo ngokubanzi, ngelixa umbhobho we-CDW usetyenziswa kwicandelo loomatshini abachanekileyo.
Ukuba ukusebenza kombhobho we-CDW kufuna ukuphuculwa ngakumbi, unyango lokutsalwa kwe-annealing lunokongezwa (ukuphelisa uxinzelelo lokusebenza olubandayo).
