Njengamanje zinjenezindlela ezimbili eziphambili zokufaka esimweni esivikelayo: Ukushaya umuntu ovikela ngaso ohlangothini lwethafu eliseceleni, kanti elinye likhona umkhathi wokuvikela ama-coaxial.
Ungazikhetha kanjani izindlela ezimbili zokushaya iziqu kufanele zibhekwe ngezindlela eziningi. Ezimweni eziningi, kunconyelwa ukusebenzisa umkhathi wokuvikela ophetha we-side.
Umgomo wokukhetha indlela yokushaya umkhathi wokuvikela
Into yokuqala edinga ukucaca ukuthi lokho okubizwa ngokuthi yi-Weld okuthiwa yi-Weld kuyindlela elula yokuqonda kalula. Ngokweqiniso, ezinye izakhi ezisezingeni eliphansi kanye nezinto ezisemoyeni zisabela ngamakhemikhali ukwenza ikhwalithi ye-weld ukuze iwohloke. Okuvame kakhulu ukuthi izingxenye zensimbi ezisebenzayo ze-Weld Cerminal Cerminaly nge-oksijini, i-nitrogen, ne-hydrogen emoyeni emazingeni okushisa athile.
Ukuvimbela i-weld kusuka ekubeni yi- 'oxidised ' ukunciphisa noma ukuvimba izinto ezinjalo ezisebenzayo ekuxhumaneni nezinto zensimbi eWeld ngamazinga okushisa aphezulu. Njengoba sonke sazi, izinga lokushisa eliphakeme lingenza imisebenzi yamangqamuzana isebenze kakhulu. Lesi simo sokushisa esiphakeme akuyona nje kuphela i-molten pool Metal, kepha futhi sifaka isikhathi sonke kusuka lapho insimbi ye-weld incibilika lapho i-molten pool metal iqinisa khona ukuqina kwamazinga okushisa athile.
Isibonelo, lapho i-welding titanium alloy, lapho izinga lokushisa lifinyelela kuma-300 ℃ noma ngaphezulu, i-titanium alloy ingadonsa ngokushesha i-hydrogen emoyeni; Lapho ingaphezulu kwama-450 ℃, izodonsa ngokushesha umoya-mpilo emoyeni; Lapho ifinyelela kuma-600 ℃ noma ngaphezulu, ingadonsa ngokushesha umoya ku-nitrogen. Ngakho-ke, ngemuva kokuthi ama-titanium alloy ama-welds aqinisekiswa futhi izinga lokushisa lincishiswa okungenani ama-300 ℃, badinga ukuvikeleka ngempumelelo ukuze bahlukanise umoya, ngaphandle kwalokho ama-welds azobe esolwa phakathi kwechibi elibunjiwe kanye ne-base yensimbi.
Ukuze uqinisekise kangcono ikhwalithi yeWeld ngesikhathi iWeld ipholile kumazinga okushisa athile, I-Hanao Tech (Seko Tech (Seko Imishini) iyengeze ngobusuku obuvikelweni ebhokisini le-Welding of the Imishini yokukhiqiza amapayipi ephakeme kakhulu ye-Welding . Lapho ithoshi le-welding lisebenza, umoya wokuvikela uwohloka ngokuzenzakalelayo ebhokisini ukuze alondoloze ukugxila okuthile ngesilinganiso esithile sokugeleza ukuze afinyelele inhloso yokushayela umoya. Umhubhe womkhathi ovikelayo onobude obungama-30 cm naye wengezwa ukuvimbela izinga lokushisa eliyinsalela kusuka ku-oxidizing the wald.
Ukusuka encazelweni engenhla, singazi ukuthi ukujova umkhathi wokuvikela akudingeki ukuvikela ichibi le-weld kuphela, kodwa futhi kudinga ukuvikelwa kwendawo engaqediwe ngemuva kokuthi i-welding iqediwe, ngakho iningi labo lizosebenzisa umkhathi ovuthayo weShow-shap. Ngoba uma kuqhathaniswa nendlela yokuvikela ama-coaxial, le ndlela inebanga elibanzi elibanzi, ikakhulukazi endaweni lapho i-weld isanda kuqinisekiswa khona.
Kodwa-ke, kuzinhlelo zokusebenza zobunjiniyela, akuyona yonke imikhiqizo engafakwa eceleni kwe-Side-Shaft Side blowing igesi evikelayo. Eminye imikhiqizo ekhethekile, kuphela indlela yokushaya kwe-coaxial yegesi evikelekile ingasetshenziswa, futhi uhlobo oluhlanganyelwe lwesakhiwo somkhiqizo ludinga ukukhethwa ngendlela eqondisiwe.
Ukukhetha kwendlela ethile yokuvikela umkhathi
1) iqonde i-Weld
Uma ukwakheka kwe-weld komkhiqizo kuqondile, kungaba yi-butt ehlanganisiwe, i-LAP ngokuhlangene, okuhlangene kwegumbi langaphakathi noma ukuhlanganiswa kwe-weverlap. Lolu hlobo lomkhiqizo lufanelekile ukusebenzisa umkhathi wokuvikela ohlangothini.
2) Plane evaliwe i-graphic weld
Uma ukwakheka kwe-weld yomkhiqizo kuveza isimo esivaliwe njengendilinga eyisicaba, i-polygon eyisicaba, kanye ne-polyline eyisicaba, futhi kuyindlela ehlanganyelwe efana ne-butt ehlanganayo, i-adge ehlanganisiwe. Lolu hlobo lomkhiqizo lusebenzisa indlela yokuvikelwa kwegesi yama-coaxial, futhi umphumela we-welding uzoba ngcono.
Uhlobo lwesimo sokuvikela kanye nokukhethwa kwendlela yokulethwa kuthinta ngqo ikhwalithi, ukusebenza kahle kanye nezindleko zokukhiqizwa kwe-welding. Kodwa-ke, ngokubheka ukwehluka kwezinto zokwehlukaniswa, ekusebenzeni kwangempela, ukukhethwa kwezinhlobo ze-welding gesi kanye nezindlela zokulethwa kuyinkimbinkimbi ngokwengeziwe, futhi izinto ezitholwayo zidinga ukubhekwa ngokuphelele, njengezinto zomkhiqizo, indawo ye-welding, isikhundla se-welding. Kunconywa ukuqhuba isivivinyo se-welding kuqala futhi ukhethe indlela efanelekile yokulethwa kanye negesi ye-welding ukuze uzuze umphumela omuhle kakhulu we-welding.
