Ukukhetha Igesi Yokushisela Efanele: Isihluthulelo Sekhwalithi Ephelele Yokushisela kanye Nokusebenza Okuzinzile

— Umthelela Wegesi Ehlukene Ekhwalithini Yokushisela Nokuzinza Kwemishini

Ezinqubweni zokushisela,Ukukhethwa kwegesi yokuvikela kuthinta ngqo ikhwalithi yokushisela, ukuzinza kokushisela, kanye nempilo yesevisi yemishiniIkakhulukazi ekushiseni nge-laser kanye nokunemba okuphezulu

ukusetshenziswa kokushisela, ukukhethwa okufanele kwegesi yokuvikela kuyisici esibalulekile ekuqinisekiseni ukusebenza kokushisela okuqhubekayo kanye nokuthembeka kwenqubo.

Lesi sihloko sinikeza umbono ohlelekile wezinto ezisetshenziswa kakhului-laser ye-soldadoraamagesi kanye nezimo zokusetshenziswa kwawo.

Imisebenzi Eyinhloko YOKUQALA Yamagesi Okushisela

Ngesikhathi sokushisela, izinga lokushisa lendawo yokushisela likhuphuka ngokushesha esikhathini esifushane kakhulu. Insimbi ingena esimweni sokuncibilika noma sokuncibilika kancane futhi ingasabela kalula nomoya-mpilo kanye ne-nitrogen emoyeni.

Imisebenzi eyinhloko yokuvikela amagesi ihlanganisa:

Ukuhlukanisa indawo yokushisela emoyeni ukuze kuvinjelwe ukushiswa kanye nokushintsha kombala

Ukuqinisa ichibi elincibilikisiwe nokuthuthukisa ukuqina kokwakheka kwe-weld

Ukunciphisa ukugoba, ukuchitheka, kanye nezinye izinkinga zokushisela

Ukuthuthukisa ukubukeka kwe-weld kanye nekhwalithi yomkhiqizo iyonke

Ukuvikela izibani zokushisela, ama-nozzle, kanye nezingxenye ze-optical, ngaleyo ndlela kwandise impilo yesevisi yemishini

Izinhlobo Zesibili Ezivamile Zamagesi Okushisela Nezimpawu Zawo

I-nitrogen (N₂)

I-nitrogen iyigesi yokuvikela esetshenziswa kakhulu futhi engabizi kakhulu, efanelekile kakhulu ekushiseni insimbi engagqwali. Ngenxa yezindleko zayo eziphansi, i-nitrogen inikeza ukusebenza okuhle kakhulu ezindaweni eziningi.

izinhlelo zokusebenza zokushisela.

Izici Eziyinhloko:

Ukusebenza kokuvikela okuzinzile ngezindawo zokushisela ezihlanzekile nezibushelelezi

Kusiza ekufezeni ukubukeka okuhle kwe-weld

Ukusebenza kahle kwezindleko eziphakeme, okufanelekela ukukhiqizwa okuqhubekayo

Izicelo Ezinconyiwe:

Ukushisela insimbi engagqwali (kunconywa kakhulu)

Ukushisela ishidi elincane

Izicelo ezinezidingo eziphezulu zokubukeka kwe-weld kanye nokuvumelana

Ngokushisela insimbi engagqwali, i-nitrogen inconywa kakhulu njengoba inikeza imiphumela yokushisela ezinzile futhi engcono kakhulu.

I-Argon (i-Ar)

I-Argon iyigesi engasebenzi kahle enezakhiwo zamakhemikhali ezizinzile futhi ingenye yamagesi okuvikela asetshenziswa kakhulu ekusetshenzisweni kokushisela.

Izici Eziyinhloko:

Ayisebenzi ngamakhemikhali futhi akunakwenzeka ukuthi isabelane nezinsimbi

Ukusebenza kokuvikela okuzinzile ngokwakhiwa okuhle kwe-weld

Ifanele izinto ezahlukahlukene

Izicelo Ezinconyiwe:

Ukushisela insimbi yekhabhoni

Ukushisela insimbi engagqwali

Ama-alloy e-aluminium kanye nezinye izinsimbi ezingezona i-ferrous

I-Helium (He)

I-Helium inokushisa okuhle kakhulu kanye namandla aphezulu e-ionization, yize ibiza kakhulu.

Izici Eziyinhloko:

Kwandisa ukujula kokungena kwe-weld

Kuthuthukisa ukuzinza kokushisela

Isebenza kahle kakhulu ezintweni ezibonisa ukukhanya okuphezulu

Izicelo Ezinconyiwe:

Ukushisela i-aluminium ne-aluminium alloy

Ukushisela i-alloy yethusi neyethusi

Izinhlelo zokusebenza ezidinga ukungena okukhulu kwe-weld

IZINTO EZIYINHLOKO ZESITHATHU EKUKHETHWENI KWEGESI LOKUSHISA

Ezisetshenzisweni ezisebenzayo, ukukhethwa kwegesi yokushisela kufanele kusekelwe ekuhlolweni okuphelele kwalezi zinto ezilandelayo:

1. Uhlobo lwezinto zokushisela

2.Ubukhulu be-Workpiece kanye nenqubo yokushisela

3. Izidingo zokubukeka kwe-weld kanye namandla omshini

4. Ukusebenza kahle kokukhiqiza kanye nokulawula izindleko

5. Uhlobo lwemishini kanye nokuhambisana kwegesi

Kuphela uma ukukhetha igesi yokuvikela kuhambisana kahle nemingcele yokushisela lapho izinzuzo zokusebenza ezigcwele zomshini wokushisela zingabonakala khona.

Amagesi ESINE Awakanconywa Ukusetshenziswa

Amagesi Axubile

Nakuba amagesi axubile anganikeza izinzuzo ezithile kwezinye izinqubo zokushisela ezivamile, awanconywa ekushiseleni okunembile noma ekushiseleni nge-laser ngenxa yalokhu okulandelayo

izizathu:

Ukwakheka kwegesi okungazinzile

Ingozi eyengeziwe yokushiswa kwe-weld kanye nokushintsha kombala ngokungalingani

Ubunzima bokugcina ikhwalithi yokushisela ihambisana njalo

Amagesi axubile awanconywa ekushiseni nge-laser noma ekushiseni kwekhwalithi ephezulu.

I-Carbon Dioxide (CO₂)

I-carbon dioxide iyigesi esebenzayo engabola kalula ngaphansi kwezimo zokushisela ezishisa kakhulu.

Izinkinga Eziyinhloko:

Ingozi ephezulu yokushiswa kwe-weld

Ukubukeka kwe-weld emnyama kanye nokwakheka okubi

Ukwanda kokuchitheka kwamanzi kanye namazinga aphezulu okukhubazeka

Ukuguguleka okusheshayo kwezibani zokushisela kanye nezingxenye ze-optical

I-CO₂ ayinconywa nhlobo ekusetshenzisweni kokushisela insimbi engagqwali noma ukushisela nge-laser.

Isiphetho

Nakuba ukuvikela igesi akuyona ingxenye eyinhloko ye-umshini wokushisela we-fiber laser, kuyipharamitha yenqubo ebalulekile enquma ngqo ikhwalithi yokushisela kanye nokuqina kohlelo. Ngokwemvelo

ukusetshenziswa, igesi yokuvikela kufanele ikhethwe ngokwesayensi ngokuya ngezinto zokushisela, izidingo zenqubo, kanye namazinga ekhwalithi.

Ngokushisela insimbi engagqwali, i-nitrogen inconywa kakhulu, kuyilapho amagesi axubile kanye ne-carbon dioxide kufanele kugwenywe ukuqinisekisa ikhwalithi yokushisela, ukuphepha kwemishini, kanye nokuqina kwesikhathi eside.

ukusebenza.

Ukukhetha igesi ngendlela efanele kubalulekile ukuze kusetshenziswe ngokugcwele izinzuzo zokusebenza kwayo.imishini yokushisela nge-laserkanye nokuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.
