Ukuminyana kwamanje kuwumqondo obalulekile endaweni yemishini yokushisela izinqe.Idlala indima ebalulekile ekunqumeni ukusebenza kahle kanye nekhwalithi yenqubo yokushisela.Lesi sihloko sihlose ukuchaza ukubaluleka kwamanje kokuminyana emishinini yokushisela izinqe, ukubala kwayo, kanye nomthelela wayo ezicini zokushisela.
- Incazelo Yokuminyana Kwamanje: Ukuminyana kwamanje kubhekisela enanini lamandla kagesi agelezayo endaweni enikeziwe enqamula ingxenye yesiqeshana sokusebenza phakathi nenqubo yokushisela.Ngokuvamile kukalwa ngama-ampere ngemilimitha yesikwele (A/mm²).Ukuqonda nokulawula ukuminyana kwamanje kubalulekile ukuze kuzuzwe imiphumela elungile yokushisela.
- Ukubala Ukuminyana Kwamanje: Ukuze ubale ukuminyana kwamanje, hlukanisa i-welding current (kuma-ampere) ngendawo enqamulayo yendawo yokusebenza (ngamamilimitha ayisikwele) endaweni yokushisela.Lesi sibalo siveza inani lamanje lokuminyana, okuyipharamitha engukhiye ethonya amandla e-weld, ukujula kokungena, nendawo ethinteke ukushisa.
- Umthelela Ezicini Ze-Weld: Ukuminyana kwamanje kuthinta kakhulu umphumela wenqubo yokushisela.Ukuminyana okuphezulu kwamanje kungaholela ekungeneni okujulile, isivinini sokushisela esisheshayo, nokufakwa kokushisa okwandisiwe.Kodwa-ke, ukuminyana kwamanje okweqile kungaholela ekungeneni ngokweqile, ukuhlanekezela, kanye nokukhubazeka okungenzeka ekuhlanganyeleni kwe-weld.
- Ukuthuthukisa Ukuminyana Kwamanje: Ukugcina ukuminyana okufanele kwamanje kubalulekile ukuze uthole amashisela ekhwalithi ephezulu.Ama-opharetha ama-welding kufanele acabangele izici ezihlukahlukene, njengohlobo lwempahla, ukujiya, nokucushwa kwamalunga, ukuze kuthuthukiswe ukuminyana kwamanje.Ngokulungisa amandla e-welding yamanje kanye ne-electrode, ama-welders angakwazi ukuhlanganisa ukuminyana kwamanje ukuze afinyelele izici ezifiselekayo zokushisela.
- Ukulawula Ukushisa Nokusebenza Kahle: Ukulawula ukuminyana kwamanje kubalulekile ekulawuleni okokufaka ukushisa ngesikhathi sokushisela.Ukuminyana kwamanje okulawulwa kahle kuqinisekisa ukuthi inani elifanele lokushisa lisetshenziselwa ukudala i-weld eqinile nefanayo ngaphandle kokubangela ukushisa noma ukushisa okungaphansi kwendawo yokusebenza.
- Ithonya Kumandla Weld: Ukuminyana kwamanje kudlala indima ebalulekile ekunqumeni amandla nobuqotho be-weld.Ukuminyana okufanelekile kwamanje kuqinisekisa ukuhlangana okufanele kanye nesibopho sensimbi phakathi kwezinsimbi eziyisisekelo, okuholela ekuhlanganyeleni okuthembekile nokuqinile.
Sengiphetha, ukuminyana kwamanje kuyipharamitha ebalulekile emishinini yokushisela izinqe ethinta ngokuqondile ikhwalithi nokusebenza kahle kwenqubo yokushisela.Ukuqonda umqondo wokuminyana kwamanje kanye nomthelela wawo ezicini ze-weld kwenza abaqhubi be-welding benze izinqumo ezinolwazi futhi bathole imiphumela emihle ye-weld.Ngokulawula ngokucophelela ukuminyana kwamanje, ama-welders angakhiqiza ama-welds aphezulu ahlangabezana nezidingo zezinhlelo zokusebenza nezimboni ezihlukahlukene.
