Izinkinga zokushisela ngezinye izikhathi zihlangana ngesikhathi sokufakwa kwamashubhu ensimbi ye-carbon.Ngakho-ke, kanjani ukushisela amashubhu?Yini okufanele siyinake lapho sishisela amashubhu e-carbon steel?

1. Ukushisela igesi
Ukushisela igesi kungasetshenziselwa ukushisela, okuwukuhlanganisa igesi evuthayo negesi esekela ukuvutha ndawonye, ​​ukuyisebenzise njengomthombo wokushisa ilangabi, bese uyancibilika futhi ushisele amapayipi ndawonye.

2. Ukushisela i-arc

I-arc welding nayo ingasetshenziswa, okungukuthi, i-arc welding isetshenziswa njengendlela yokushisela.Umthombo wokushisa ohlanganisa amapayipi ndawonye.Le ndlela yokushisela ivame ukusetshenziswa ekukhiqizeni izimboni.Ngaphezu kwalezi zindlela ezimbili ezingenhla, ipayipi elishiselwe lingasebenzisa i-welding yokuxhumana, futhi indlela ethize okufanele ihlanganiswe incike ezintweni kanye nezidingo zepayipi.

Insimbi iqukethe insimbi nekhabhoni enenani elincane lezinsimbi ezixubile, njenge-manganese, i-chromium, i-silicon, i-vanadium, ne-nickel.Insimbi enekhabhoni ephansi iqukethe kuphela amaphesenti angu-0.3 yekhabhoni, okwenza kube lula kakhulu ukuyishisela.
Ikhabhoni emaphakathi iqukethe amaphesenti angu-0.30 kuya kwangu-0.60 ekhabhoni, kanye nezinsimbi zekhabhoni eziphezulu ku-0.61 kuya ku-2.1 wamaphesenti ekhabhoni.Uma kuqhathaniswa, i-cast iron iqukethe amaphesenti angaba ngu-3 yekhabhoni, okwenza kube inselele emangalisayo ukushisela.

Izinyathelo zokuqapha ze-Carbon steel tube welding:

1. Ngaphambi kokuba ipayipi lishiselwe, kuyadingeka ukususa yonke imfucumfucu epayipini.Ngemva kokuqedwa kokwakhiwa, ipuleti lokuvimbela lingasetshenziswa ukuze livalwe ukuze kuvinjelwe udoti ukuba ungangeni kuwo.Ngesikhathi esifanayo, ngaphambi kwe-welding, kuyadingeka ukupholisa amabala amafutha engxenyeni ye-nozzle kuze kube yilapho kuvela i-luster efana nensimbi.

2. Ngokuvamile, impahla yepayipi ngokuyisisekelo i-spiral welded pipe, ngakho-ke indlela yokushisela ye-arc manual ingakhethwa.Kulolu hlobo lwepayipi, wonke ama-welds adinga ukufakwa phansi nge-argon arc welding, futhi ikhava idinga ukuba Gcwalisa nge-arc welding ye-manual.
