Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nabasika - Imboni Yokushisela & Cutting yase-China & Suppliers (xinfatools.com)
Izinto ezithinta ukuzinza kwe-arc yokushisela ikakhulukazi zihlanganisa izici ezilandelayo:
(1) Amakhono wokushisela kanye nekhono lokulungisa ubude be-arc okuzenzakalelayo
Indlela yokusebenza komshiseli iyisici esibalulekile ekunqumeni ukuzinza kwe-arc. Ngesikhathi senqubo yokushisela, ukuthinta kwesibhamu somshiseli (umcu) kufanele kube ngokufanele futhi ubude be-arc kufanele bugcinwe bulingana ngangokunokwenzeka. Uma kungenjalo, ukushintshashintsha kwamanje kokushisela noma ukuphazamiseka kwe-arc kuzokwenzeka. I-engeli ephakathi kwentambo yokushisela kanye ne-workpiece, naphakathi kwesibhamu sokushisela kanye nendawo yokusebenza, kufanele ifanele ukukhiqiza ukungena okufanele, ukuvimbela ukukhubazeka kokushisela, nokugcina ichibi elincibilikisiwe. Ukuze uthole ukushisela okuzenzakalelayo, ubude be-arc budingeka ukuthi bulungiswe ngokuzenzakalelayo ukuze kuqinisekiswe ukuthi ubude be-arc buhlala buhlala buhlala njalo ngesikhathi senqubo yokushisela, ngaleyo ndlela kuqinisekiswe imingcele ye-welding eqhubekayo.
(2)Arc welding power supply
① Izinhlobo zemithombo yamandla okushisela i-arc: Imithombo yamandla e-DC arc welding kanye nemithombo yamandla e-square we-AC arc welding inokuqina okungcono kwe-arc kunemithombo yamandla yokushisela ye-sine wave AC arc. Ukuzinza kwe-pulse arc welding power supply kungcono, ngakho-ke, ukunikezwa kwamandla we-pulse arc welding kuvame ukusetshenziswa lapho kushiselwa nge-current encane.
②Izici zangaphandle zokunikezwa kwamandla we-arc welding Izici zangaphandle zokunikezwa kwamandla kufanele zihambisane nezidingo zokuvutha okuzinzile kwe-arc zendlela ehambisanayo yokushisela. Igesi yensimbi yokushisela i-arc ngokuvamile isebenzisa intambo encane (ububanzi bocingo abukho ngaphezu kuka-3.2mm), futhi isici samandla sangaphandle esihamba kancane sidinga ukukhethwa, ngaphandle kwalokho i-welding ye-Gas metal arc welding ene-arc engazinzile kanye namandla aphezulu ngezinye izikhathi. futhi isebenzisa ucingo oluwugqinsi. Uma usebenzisa ucingo oluwugqinsi, kuyadingeka ukusebenzisa umthombo wamandla onezici zangaphandle eziwayo.
③Izici eziguqukayo zokunikezwa kwamandla zifaka phakathi ukuguquka kwesiyingi esifushane. I-CO2 welding arc iyasha futhi icime ngezikhathi ezithile. Lokhu kudinga amandla kagesi angalayishi ukuthi akhuphuke ngokushesha kanye nogesi wesekethe emfishane ukuthi ukhuphuke ngokulingene.
④I-voltage engalayishi ye-arc welding power supply. Ukuphakama kwe-voltage engekho yomthwalo we-arc welding power supply, kuba lula ukuqala i-arc kanye nokuzinza okungcono kokuvutha kwe-arc. Kodwa-ke, lapho i-voltage engekho umthwalo iphezulu kakhulu, ilimaza ukuphepha komuntu siqu komshiseli.
(3)Welding current
I-current welding enkulu, izinga lokushisa eliphakeme le-arc, linamandla izinga le-ionization yegesi kanye nokukhishwa kokushisa endaweni yekholomu ye-arc, futhi ukushiswa kwe-arc kuyoba kuzinzile.
(4) I-arc voltage
I-voltage ye-arc kufanele ifane kahle ne-welding current. Njengoba i-welding current ikhula, i-arc voltage kufanele ikhule. Lapho i-welding current ihlala njalo, uma i-arc voltage incane kakhulu, kulula ukubangela isifunda esifushane; uma i-arc voltage inkulu kakhulu, i-arc izoshwibeka ngobudlova futhi ibhubhise ukuzinza kwe-arc welding.
(5) Isimo esingaphezulu kwendawo yokusebenza, ukugeleza komoya kanye nokuphambuka kukazibuthe
Uma ingaphezulu le-workpiece lingahlanzekile, njengamafutha, ukugqwala, umswakama, njll., ukuthungela i-arc kanye nokushiswa kwe-arc ngeke kuzinzile. Uma ukugeleza komoya ovikelayo kungazinzi noma kukhona ukuchezuka kwamagnetic, i-arc izophinde ingazinzi.
