Yimuphi u-Electrode osetshenziselwa ukushisela insimbi engagqwali?

Ukukhetha i-electrode yokushisela efanele kubalulekile kumaphrojekthi ensimbi engagqwali kusukela kumishini yasekhishini kuya ezingxenyeni zamakhemikhali ukuvimbela ukushisela okubuthakathaka, ukugqwala, noma ukushintsha kombala. Ama-electrode avame kakhulu avela ochungechungeni lwe-E308, E309, E316, kanye ne-E312. Ukukhetha okulungile kuncike ebangeni elithile lensimbi engagqwali kanye nezidingo zephrojekthi, okuqinisekisa ukushisela okuqinile, okumelana nokugqwala, futhi okwamukelekayo ngokubonakalayo.

Ukuqonda Ama-Electrode Okushisela Ensimbi Engagqwali

A I-Electrode Yokushisela Yensimbi Engagqwaliiyinduku yensimbi embozwe nge-flux eyenzelwe ukuhambisana nokwakheka kwensimbi eyisisekelo. I-flux izinzisa i-arc, ivikele ichibi le-weld elincibilikisiwe emoyeni nase-nitrogen, futhi isiza ekwakheni i-slag evikelayo. Isihluthulelo sempumelelo ukufanisa okuqukethwe kwe-alloy ye-electrode eduze nezinga lensimbi engagqwali oyishibilizayo. Lokhu kugcina ukumelana nokugqwala kanye nezakhiwo zemishini ze-weld eqediwe.

Izinhlobo Ezidumile Zama-Electrode Ezinsimbi Ezingagqwali Ezivamile

Nasi umhlahlandlela wezindlela ezisetshenziswa kakhuluI-Electrode Yokushisela Yensimbi Engagqwaliizinhlobo:

1. E308L-16

• Okuhle Kakhulu: Ukushisela izinsimbi ezingagqwali ze-austenitic ezingama-304 kanye ne-304L, izinhlobo ezivame kakhulu ezisetshenziswa ekuhlinzekeni ukudla, ekwakhiweni kwezakhiwo, kanye nasekukhiqizweni okuvamile.
• Kungani: U-“L” ubonisa okuqukethwe okuphansi kwekhabhoni, okunciphisa imvula ye-carbide futhi kuvimbele ukugqwala endaweni ethintekile ekushiseni. Lena yi-electrode ye-workhorse esebenzayo.

2. E316L-16

• Okuhle Kakhulu: Ukushisela izinsimbi ezingagqwali ezingu-316 kanye no-316L, eziqukethe i-molybdenum.
• Kungani: I-molybdenum eyengeziwe inikeza ukumelana okuphezulu nokugqwala kwemigodi, okwenza ibe yindawo ekahle kakhulu ekusetshenzisweni kwamakhemikhali, olwandle, kanye nemithi lapho ukuchayeka kuma-chloride kuyinkinga.

3. E309L-16

• Okuhle Kakhulu: Ukushisela okuhlukile, njengokuhlanganisa insimbi engagqwali nensimbi ethambile noma ukumboza insimbi yekhabhoni ngensimbi engagqwali. Kuphinde kusetshenziswe ukushisela insimbi engagqwali engu-309 ngokwayo.
• Kungani: Inokuqukethwe okuphezulu kwe-chromium kanye ne-nickel, okusiza ekunciphiseni ikhabhoni ensimbini ethambile futhi kuvimbele ukwakheka kwendawo eqinile, eqhekekayo ye-martensitic ku-weld.

4. E312-16

• Okuhle Kakhulu: Ukushisela izinsimbi ezingafani ezinokuqukethwe okuphezulu kwe-alloy noma ukuhlanganisa amazinga angaziwa e-stainless lapho ukuqhekeka kuyingozi khona.
• Kungani: Ikhiqiza idiphozithi yokushisela enokuqukethwe okuphezulu kwe-ferrite, okunikeza ukumelana okuhle kakhulu nokuqhekeka okushisayo futhi ibekezelela kakhulu izinsimbi eziyisisekelo ezahlukahlukene.

Izici Eziyinhloko Ekukhetheni I-Electrode Efanele

1. Qondanisa Ibanga: Zama njalo ukufanisa i-electrode nebanga lensimbi eyisisekelo. Hlola isitifiketi sezinto noma usebenzise i-spectrometer uma ungaqiniseki.
2.Cabanga Ngendawo Yesevisi: Ingabe i-weld izovezwa emazingeni okushisa aphezulu, kuma-asidi, noma emanzini anosawoti? Ezindaweni ezinzima, amalitha angu-316 avame ukudingeka.
3. Indawo Yokushisela: Isijobelelo esithi “-16″ sibonisa uhlobo lokushisela nokuthi i-electrode ifanelekela zonke izikhundla zokushisela (eziyisicaba, ezivundlile, eziqondile, ezingenhla).
4. Ukuqeda Nokuhlanzeka: Ngezinhlelo zokusebenza lapho inhlanzeko noma ukubukeka kubalulekile (njengezinto zobisi noma ukushintshwa okubonakalayo), qiniseka ukuthi usebenzisa ama-electrode aklanyelwe ubhontshisi obubushelelezi, okulula ukuwuhlanza futhi obungenawo amachaphaza amaningi.

Amathiphu Abalulekile Okuphumelela Kokushisela Insimbi Engagqwali

Insimbi engagqwali iqhuba ukushisa kancane kunensimbi yekhabhoni futhi ithambekele ekuphazamisekeni. Landela le mikhuba emihle kakhulu:

1. Sebenzisa i-Lower Heat Input: Gcina i-amperage ekugcineni okuphansi kobubanzi obunconywayo bese usebenzisa indlela ye-stringer bead ukunciphisa ukwakheka kokushisa nokuphambuka.
2. Gcina Ubude Obufushane Be-Arc: Lokhu kuthuthukisa ukuvikela igesi futhi kunciphisa ingozi yokuba nezimbobo.
3. Hlanza Ngokucophelela: Susa wonke uwoyela, amafutha, upende, kanye noyinki wokumaka endaweni ehlangene. Sebenzisa ibhulashi lensimbi engagqwali elikhethekile ukuze ugweme ukungcoliswa kwensimbi yekhabhoni.
4. Sebenzisa i-Back Purging (yezinto ezibucayi zokushisela): Lapho ushisela ipayipi noma lapho uhlangothi lwangemuva luvezwa khona ukuze lusebenze, sebenzisa igesi engasebenzi kahle ohlangothini lwangemuva ukuze uvimbele ukugcwala koshukela ngaphakathi kwe-weld eqinile, enamafutha ebulala ukumelana nokugqwala.

Izinto Ezisetshenziswayo Zokushisela Ezisezingeni Eliphezulu

Kwabashiseli, abakhiqizi, kanye namaqembu okulungisa, ukuhambisana kwama-electrode akho kuthinta ngqo ikhwalithi yokushisela, ukukhiqiza, kanye nezindleko zephrojekthi. Izinduku ezinephutha noma ezakhiwe ngendlela engafanele zingabangela ukuvuselelwa, ukwehluleka, kanye nezinkinga zokuphepha. Lapho kutholakalaI-Electrode Yokushisela Yensimbi Engagqwaliimikhiqizo, ochwepheshe bavame ukubeka phambili abahlinzeki abanikeza ukusebenza okuthembekile kanye nezinzuzo zokuthenga ezingokoqobo.

Abakhiqizi abanamathela ezindinganisweni zomhlaba wonke eziqashelwayo banikeza isiqinisekiso sekhwalithi nokusebenza. Kuma-workshop, izindawo zokukhiqiza imikhumbi, noma izinkampani zokwakha ezenza amaphrojekthi amakhulu noma aphindaphindayo, ukufinyelela emananini okuncintisana kanye nenethiwekhi yokuhlinzeka yomhlaba wonke ethembekile kungenza kube lula ukusebenza futhi kuthuthukise isabelomali. Ukubambisana nomhlinzeki ophethe ukukhetha okuphelele kwezinto zokushisela nakho kwenza kube lula ukuphathwa kwempahla, kuqinisekiswe ukuthi i-electrode efanele ihlala itholakala emsebenzini okhona.

Isincomo Sokugcina
Ukukhetha i-electrode efanele kubalulekile. Ngensimbi engagqwali engu-304/304L evamile, qala nge-E308L-16. Ukuze uthole isevisi yasolwandle noma yamakhemikhali ngensimbi engu-316, sebenzisa i-E316L-16, kodwa qinisekisa njalo insimbi eyisisekelo kanye nezidingo kuqala. Ukushisela okuphumelelayo kuncike ekulawuleni ukufakwa kokushisa nokugcina ukuhlanzeka okungenaphutha. Ngokusebenzisa i-electrode kanye nobuchwepheshe bokushisela insimbi engagqwali obufanele, ungakhiqiza ukushisela okuhlanzekile, okuqinile, nokungagqwali okuhlangabezana nezindinganiso eziphakeme.
