I-Rotation welding ihambisana ne-welding engaguquki ekushiseni kwamapayipi. I-welding ehleliwe isho ukuthi i-welding joint ayikwazi ukunyakaza ngemuva kokuthi iqembu lepayipi liqondaniswe, futhi ukuthungatha kwenziwa ngokuvumelana nokushintsha kwesimo se-welding (izinguquko ezivundlile, eziqondile, phezulu naphakathi) ngesikhathi senqubo yokushisela.
Ukuzungezisa imbobo yokushisela ukuzungezisa imbobo yokushisela ngesikhathi senqubo yokushisela ukuze i-welder ikwazi ukwenza ukushisela endaweni ekahle (eyokuvundlile, eqondile, phezulu naphansi).
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nabasika - Imboni Yokushisela & Cutting yase-China & Suppliers (xinfatools.com)
Eqinisweni, ukukhuluma nje, ijoyinti yokushisela engaguquki iwumthungo we-weld oshiselwe esizeni, ohlobene nepayipi elakhiwe ngaphambili.
I-welding ehlanganisiwe isho ukuthi ipayipi alinyakazi, futhi i-welder yenza i-welding nxazonke, ikakhulukazi lapho indlela yokushisela iphezulu, indlela yokushisela akulula ukuyisebenzisa, izidingo zobuchwepheshe zomshini wokushisela ziphezulu, futhi amaphutha ajwayele zenzeka. Ngokuvamile, ukwakhiwa kugalari yamapayipi;
Imbobo ezungezayo iyipayipi elingazungeziswa. Isikhundla sokushisela i-welding eyisicaba noma i-welding eqondile. Ukusebenza kwe-welding kulula futhi kuneziphambeko ezimbalwa. Ngokuyisisekelo yakhiwe phansi noma phansi.
Ngesikhathi sokuhlolwa kokushisela, ukuze kuvinjwe zonke izimbobo ezijikelezayo ukuthi zingakhethwa ngokungahleliwe ukuze zihlolwe, izinga lokuphasa liphezulu, futhi ingxenye ethile yezikebhe ezingashintshi kufanele ihlolwe ngokungahleliwe ukuze kuqinisekiswe ikhwalithi yokushisela yalo lonke ipayipi. I-"Pressure Pipeline Safety Technology Supervision Regulations-Industrial Pipeline" ibeka ukuthi isilinganiso sokutholwa kwamajoyinti okushisela angashintshi akumele sibe ngaphansi kuka-40%.
Ngokuvamile, sisebenzisa imbobo engaguquki njengembobo esebenzayo. Imbobo esebenzayo iyinhlanganisela yokushisela eseyakhiwe ngaphambili yepayipi, futhi ingxenye yepayipi inganyakaziswa noma ijikelezwe lapho ipayipi lenziwe ngaphambili ngaphandle kwesayithi. Imbobo egxilile iyimbobo efakwe isayithi eshiselwe lapho ipayipi lingakwazi ukuhanjiswa noma ukuzungeziswa.
Ekucacisweni kwepayipi lebanga elide, kubizwa ngokuthi "ukuphela kokushayisana", futhi kuyadingeka ukuthi "ukuhlolwa kwe-radiographic okungu-100% kufanele kwenziwe". I-engeli ye-welding ephelile iyinkimbinkimbi, futhi ikhwalithi yokushisela akulula ukuyiqinisekisa.
Ama-weld alungisiwe ahlobene nama-weld ajikelezayo.
Ijoyinti le-welding elijikelezayo lisho ukuthi i-welder ingakwazi ukushintshanisa ngokukhululekile ijoyinti lokushisela ngokuvumelana ne-engeli enethezeke kakhulu yomsebenzi wokushisela ngesikhathi senqubo yokushisela esenziwe ngaphambili yepayipi, futhi izinga lokushisela lizinzile, ngakho abashiseli bathanda lolu hlobo lwejoyinti lokushisela.
Kodwa-ke, ngenxa yezidingo zezimo zesayithi noma izimo ze-workpiece ngokwayo, i-welding joint of some workpieces ingalungiswa kuphela, okubizwa ngokuthi i-welding welding joint. Lapho i-welding ehlanganisiwe ye-welding ifakiwe futhi i-welded, kukhona i-joint welding eyodwa kuphela. Lolu hlobo lwejoyinti lokushisela kunzima ukulushisela, futhi ingxenye yokuhlolwa okungabhubhisi iphezulu.
Kwezinye izichasiselo zokwakhiwa kwamapayipi, ingxenye yokutholwa kwe-weld engashintshi icaciswa ngokucacile. Ngenxa yokuthi ama-engeli we-welds engaguquki ahlukile, i-welding manual izoshintshashintsha, futhi ikhwalithi ye-welds izothinteka ngezinga elithile. Isibonelo, ama-welds ahleliwe amapayipi ensimbi adinga ukuthi ama-welders enze yonke indawo ye-welding, edinga izidingo eziphezulu zama-welders. Yiqiniso, inqubo iphezulu futhi izinga lobuchwepheshe liphezulu. Umshiseli omuhle akanandaba.
Ekulawulweni kokwakhiwa, inani lokuvuleka okuhleliwe kufanele lincishiswe ngangokunokwenzeka. Ngakolunye uhlangothi, ikhwalithi ye-welding ingalawulwa, futhi ngesikhathi esifanayo, inani lokuvuleka kokuhlola lingancishiswa ukuze kuncishiswe izindleko.
