Iindidi zeMibhobho
Imibhobho ihlelwa ngamaqela amabini: imibhobho engenamthungo kunye nemibhobho edibeneyo, esekelwe kwindlela yokuvelisa. Imibhobho engenamthungo yenziwa kwinqanaba elinye ngexesha lokuqengqeleka, kodwa imibhobho egobileyo ifuna inkqubo ye-welding emva kokuqengqeleka. Imibhobho edityanisiweyo inokwahlulwa ibe ziindidi ezimbini ngenxa yobume bomdibaniso: i-spiral welding kunye ne-welding straight. Nangona kukho ingxoxo malunga nokuba imibhobho yentsimbi engenamthungo ibhetele kusini na kunemibhobho yentsimbi egobileyo, zombini abenzi bemibhobho engenamthungo nedityanisiweyo banokuvelisa imibhobho yentsimbi enomgangatho, ethembekileyo, neyomeleleyo xa ithelekiswa nomhlwa. Ingqwalasela ephambili kufuneka ibe kwiinkcukacha zesicelo kunye neenkalo zeendleko xa umisela uhlobo lombhobho.

Umbhobho ongenamthungo
umbhobho ongenamthungo udla ngokuveliswa ngokwamanyathelo antsonkothileyo aqala ngokugrumba umngxuma kwibillet, umzobo obandayo, kunye nenkqubo yokuqengqeleka ebandayo. Ukulawula ububanzi obungaphandle kunye nobukhulu bodonga, imilinganiselo yohlobo olungenamthungo kunzima ukulawula xa kuthelekiswa nemibhobho edibeneyo, ukusebenza okubandayo kuphucula iimpawu zoomatshini kunye nokunyamezela. Olona ncedo lubalulekileyo lwemibhobho engenamthungo kukuba inokuveliswa ngobungqingqwa bodonga olungqingqwa nolunzima. Ngenxa yokuba akukho zithungo ze-weld, zinokuthi zithathwe njengezixhobo ezingcono zoomatshini kunye nokumelana nokubola kunemibhobho edibeneyo. Ukongeza, imibhobho engenamthungo iya kuba ne-ovality engcono okanye ukujikeleza. Zihlala zisetyenziswa kakuhle kwiimeko ezinzima zokusingqongileyo ezifana nemithwalo ephezulu, uxinzelelo oluphezulu, kunye neemeko ezinobungozi kakhulu.

Umbhobho odityanisiweyo
Umbhobho wentsimbi odityanisiweyo wenziwa ngokudibanisa ipleyiti yentsimbi eqengqelekayo ibe yimilo ye-tubular usebenzisa ijoint okanye i-spiral joint. Ngokuxhomekeke kwimilinganiselo yangaphandle, ubukhulu bodonga, kunye nesicelo, kukho iindlela ezahlukeneyo zokwenza imibhobho edibeneyo. Indlela nganye iqala nge-billet eshushu okanye i-flat strip, eyenziwa ibe yimibhobho ngokolula i-billet eshushu, idibanise imiphetho kunye, kwaye itywine nge-weld. Imibhobho engenamthungo inonyamezelo olungqingqwa kodwa ukuqina kodonga olucekethekileyo kunemibhobho engenamthungo. Amaxesha amafutshane okuhanjiswa kunye neendleko eziphantsi zinokuchaza ukuba kutheni imibhobho egobileyo inokukhethwa kunemibhobho engenamthungo. Nangona kunjalo, ngenxa yokuba ii-welds zinokuba ziindawo ezinovakalelo ekwandeni kokuqhekeka kwaye zikhokelela ekuqhekekeni kwemibhobho, ukugqitywa komphezulu wemibhobho yangaphandle kunye nengaphakathi kufuneka ilawulwe ngexesha lokuvelisa.
