Ukushisela amafreyimu etafula lensimbi engagqwali kuyinqubo ebalulekile edinga ulwazi namakhono ochwepheshe.Insimbi engagqwali iyinsimbi engagqwali, ngakho-ke kudingeka ukunakwa okukhethekile ngesikhathi senqubo yokushisela ukuze kuqinisekiswe ikhwalithi nokuqina kwejoyinti elishiselwe.
Okokuqala, ukukhetha indlela efanele yokushisela kubalulekile.Ozimele betafula lensimbi engagqwali, izindlela zokushisela ze-TIG (i-argon arc welding) noma i-MIG (i-metal inert gas welding) zivame ukusetshenziswa.I-TIG yokushisela ifanele izikhathi ezinezidingo eziphakeme ekubukekeni kwe-welding kanye nekhwalithi, kuyilapho ukushisela kwe-MIG kulungele izikhathi ezinezidingo eziphakeme ekusebenzeni kahle kokukhiqiza.
Okwesibili, ukukhetha izinto zokushisela ezifanele kubaluleke kakhulu.Amafreyimu etafula ensimbi engagqwali ngokuvamile ashiselwa ngezintambo zensimbi engagqwali zento efanayo noma efanayo.Lokhu kuqinisekisa ukuthi i-welded joint inezakhiwo ezifanayo kanye nokumelana nokugqwala kwensimbi eyisisekelo.
Ngaphambi kokushisela, amajoyinti ashiselwe kanye nesisekelo sensimbi kudingeka kuhlanzwe ngokugcwele futhi kufakwe ngaphambili ukuze kukhishwe ukungcola okungaphezulu nama-oxides futhi kuqinisekiswe ikhwalithi yokushisela.Ngesikhathi esifanayo, ngesikhathi senqubo yokushisela, i-welding current, i-voltage kanye nesivinini sokushisela kudingeka ilawulwe ukuze amajoyini we-welding afane futhi aqine.
Ekugcineni, ngemva kokuqedwa kokufakwa kwe-welding, i-welding ehlanganisiwe idinga ukucubungula, njengokugaya, ukupholisha, njll, ukuthuthukisa ikhwalithi yokubukeka.
Ngamafuphi, ukushisela amafreyimu etafula lensimbi engagqwali kudinga ukucatshangelwa okuphelele kwezici eziningi ezifana nokukhethwa kwezinto ezibonakalayo, izindlela zokushisela, ukwelashwa kwangaphambili kanye nokwelashwa kwangemuva ukuze kuqinisekiswe ikhwalithi nokuqina kwamalunga ashiselwe.
