Uma kuyi-welding ye-arc manual, okokuqala, qaphela ukuhlukanisa insimbi encibilikisiwe ne-coating. Qaphela ichibi elincibilikisiwe: uketshezi olucwebezelayo luyinsimbi encibilikisiwe, futhi okuntanta phezu kwalo futhi lugeleze ukunamathela.
Lapho u-welding, qaphela ukuthi ungavumeli ukunamathela kudlule insimbi encibilikisiwe, ngaphandle kwalokho kulula ukuthola i-slag, futhi udinga ukulawula isibambo se-welding ngesandla ukuze ulungise i-angle yenduku yokushisela.
Futhi, uma unomuzwa wokuthi le nqubo ilungile, ungasebenzisa i-current ephakeme, ngoba izinga eliphezulu lamanje lingakwazi ukuhlukanisa kangcono ukumbozwa kwensimbi encibilikisiwe, futhi i-welding izoba obala, kodwa kufanele ukwazi ukuyilawula. I-current ye-welding eqondile incane kunaleyo ye-welding eyisicaba, futhi i-current of overhead welding incane kunaleyo ye-welding eqondile.
Lapho ushisela, thola ukuma okunethezekile futhi okukwazi ukuqeda ukushisela ngesikhathi esisodwa, futhi ufunde ukusebenzisa isihlakala sakho ukulawula isibambo sokushisela. Uma i-carbon dioxide welding, into yokuqala okufanele uyinake ukuthi uhlale ubheka ichibi elincibilikisiwe ngesikhathi senqubo yokushisela, futhi kungcono ukusebenzisa indlela eyodwa yokulawula, futhi izinga lokugeleza kwegesi ngokuvamile liyi-18-20. Uma kungekho ukulawula okuhlangene, kufanele kulungiswe ngokuvumelana nenqubo yokushisela. Uma ucingo lwe-welding lungancibiliki noma lungancibiliki kahle, i-voltage kufanele ilungiswe phezulu, noma yamanje kufanele yehliswe. Uma i-welding wire incibilika ngamaconsi amakhulu noma indawo encibilikayo yedamu lomthamo inkulu kakhulu, kusho ukuthi i-voltage inkulu kakhulu.
Uma i-electrode ye-tungsten, ifana ne-oxygen welding, kodwa futhi unake ukuthi ubude besandiso se-electrode ye-tungsten akufanele bube bude kakhulu, futhi ukuma kwekhanda le-electrode ye-tungsten kufanele kugcinwe. Qaphela ukuthi i-welding kagesi ayikwazi ukusetshenziswa ezindaweni ezinomoya, okuzoba nomthelela omkhulu kwikhwalithi yokushisela. Ukuhlanzeka kwendawo yokushisela kufanele kuqinisekiswe futhi kufanele kunakwe nokuphepha.
Ingqikithi ithi: lawula ichibi elincibilikayo futhi ugcine ichibi elincibilikayo lisesimweni se-elliptical ngaphansi kwanoma yiziphi izimo. Bese uqedile ukushisela! Kufanele wazi ukuthi iyiphi insimbi encibilikisiwe nokuthi iyiphi enamathelayo. Lokhu kuyisisekelo. Okokuqala, kufanele wazi ukuthi iyiphi insimbi encibilikisiwe nokuthi iyiphi enamathelayo. Lokhu kuyisisekelo. Ngemva kokwazi insimbi encibilikisiwe, kungashiwo ukuthi ufunde ukushisela kagesi ekuqaleni. Konke kusekelwe kulesi sisekelo.
I-engeli ayidingi ukuphishekela amadigri angu-45, sonke siyayazi, kodwa ithintwa yizizathu eziqondile, njengobukhulu bamanje. indawo yokushisela, njll. Vele unakekele insimbi encibilikisiwe futhi ulawule idamu lomthamo futhi kuzolunga. Okubaluleke kakhulu ukushisela okuningi! Umshiseli omuhle akakwazi ukuqeqeshwa ngobusuku obubodwa. Kudingeka izinduku zokushisela eziningi ukunqwabelana!
I-Xinfa mig welding inekhwalithi enhle kakhulu nokuqina okuqinile, ukuze uthole imininingwane, sicela uhlole: https://www.xinfatools.com/mig-welding-toches/
