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, okuhlanganisa 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 ifakwe i-weld 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 angu-3 ekhabhoni, 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.
