Indlela yokusebenza ye-Argon arc welding
I-Argon arc umsebenzi lapho izandla zesobunxele nesokudla zihamba ngesikhathi esifanayo, okufana nokudweba imibuthano ngesandla sobunxele nokudweba izikwele ngesandla sokunene ekuphileni kwethu kwansuku zonke. Ngakho-ke, kunconywa ukuthi labo abasanda kuqala ukufunda i-argon arc welding babe nokuqeqeshwa okufanayo, okuzosiza ukufunda i-argon arc welding.
(1) Ukuphakelwa ngocingo: ihlukaniswe yaba ukugcwaliswa kwentambo yangaphakathi kanye nokugcwaliswa kwentambo yangaphandle.
I-filler wire yangaphandle ingasetshenziselwa ukuqala nokugcwalisa. Isebenzisa umsinga omkhulu. Ikhanda locingo lokushisela lingaphambili kwe-groove. Isandla sokunxele sincinza intambo yokushisela futhi ngokuqhubekayo siyithumela echibini elincibilikisiwe ukuze lishise. Igebe le-groove lidinga igebe elincane noma elingekho.
Izinzuzo zayo ukusebenza kahle kokukhiqiza kanye namakhono okusebenza okulula ngenxa yegebe elikhulu lamanje nelincane. Ububi bayo ukuthi uma isetshenziselwa ukwenza i-bottom, ngoba u-opharetha akakwazi ukubona ukuncibilika konqenqema olubuthuntu kanye nokuqiniswa kohlangothi olungemuva, kulula ukukhiqiza okungahlanganisiwe futhi kungatholi ukwakheka okuhle okuhlehlayo.
Intambo yokugcwalisa ingaphakathi ingasetshenziswa kuphela ukusekela ukushisela. Sebenzisa isithupha, umunwe wenkomba noma umunwe ophakathi wesandla sakho sobunxele ukuze uhlanganise isenzo sokudla ngocingo. Umunwe omncane kanye nomunwe wendandatho kubamba ucingo lokushisela ukuze ulawule lapho uya khona. Intambo yokushisela iseduze konqenqema olubuthuntu ngaphakathi kwenkundla futhi incibilika kanye nonqenqema olubuthuntu Ukuze kushiselwe, igebe lemisele liyadingeka ukuba libe likhulu kunobubanzi bocingo lokushisela. Uma kuyipuleti, intambo yokushisela ingagotshwa ibe yi-arc.
Inzuzo yayo yukuthi ngenxa yokuthi i-welding wire ingakolunye uhlangothi lwe-groove, unqenqema olungenalutho kanye nesimo sokuncibilika kocingo lwe-welding singabonakala ngokucacile, futhi ukuqiniswa okuphambene kungabonakala embonweni we-peripheral wamehlo. i-weld fusion yinhle, futhi ukuqinisa okuphambene nokungahlanganisi kungatholwa ukulawula okuhle. Okubi ukuthi ukusebenza kunzima, futhi oshiselayo kudingeka abe namakhono amaningi okusebenza. Ngenxa yokuthi igebe likhulu, umthamo we-welding uzokhula ngokufanele. Igebe likhulu, ngakho-ke lamanje liphansi, futhi ukusebenza kahle komsebenzi kuhamba kancane kunaleyo yocingo lokugcwalisa lwangaphandle.
(2) Izibambo zokushisela zihlukaniswe zibe izibambo ze-crank nama-mops.
Isibambo esinyakazayo ukucindezela umlomo wombhobho wokushisela kancane kumthungo wokushisela, bese unyakazisa ingalo kakhulu ukuze ushise. Izinzuzo zayo kungenxa yokuthi umlomo wombhobho we-welding ucindezelwe ku-weld seam, futhi isibambo se-welding sizinzile kakhulu ngesikhathi sokusebenza, ngakho-ke i-weld seam ivikelwe kahle, ikhwalithi yinhle, ukubukeka kuhle kakhulu, futhi izinga lokufaneleka komkhiqizo liphezulu. . Ithola umbala obukeka kahle kakhulu. Okubi ukuthi kunzima ukufunda, ngoba ingalo inyakaza kakhulu, ngakho-ke akunakwenzeka ukushisela ezithiyo.
I-mop isho ukuthi ithiphu yokushisela incike kancane kuyo noma ayinciki kumthungo wokushisela, umunwe omncane noma umunwe wendandatho wesandla sokudla nawo uncike kuwo noma awunciki kucezu lokusebenza, ingalo inyakaza kancane, bese ihudula isibambo sokushisela. okokushisela. Ubuhle bayo ukuthi kulula ukuyifunda futhi inokuvumelana nezimo. Ububi bayo ukuthi ukwakheka kanye nekhwalithi akunyakaziswa kahle, ikakhulukazi ukushisela ngaphandle kwe-shaker ukuze kube lula ukushisela. Kunzima ukuthola umbala nokuma okuhle uma ushisela insimbi engagqwali.
(3) I-arc ignition: I-arc ignition ivame ukusetshenziswa (i-oscillator ephezulu-frequency noma i-high-frequency pulse generator), futhi i-electrode ye-tungsten kanye ne-weldment akuxhumani ukuze kuthungele i-arc. Uma kungekho i-arc ignition, i-contact arc ignition isetshenziswa (ikakhulukazi esetshenziswa ezindaweni zokwakha) ukufakwa, ikakhulukazi ukufakwa kokuphakama okuphezulu), ithusi noma i-graphite ingafakwa emseleni we-weldment ukuze ishaye i-arc, kodwa le ndlela ingaphezulu. enzima futhi esetshenziswa kancane. Ngokuvamile, i-stroke elula enentambo yokushisela yenza i-weldment kanye ne-electrode ye-tungsten ibe mfushane ngokuqondile futhi inqanyulwe ngokushesha. Bese uvula i-arc.
(4) I-Welding: Ngemva kokuba i-arc ivutha, kuyadingeka ukushisa imizuzwana engu-3-5 ekuqaleni kwe-weldment, futhi uqale ukuphakela ucingo ngemva kokwakhiwa kwechibi elincibilikisiwe. Lapho i-welding, i-angle ye-welding wire torch kufanele ifanele, futhi ucingo lwe-welding kufanele ludliwe ngokulinganayo. Ithoshi lokushisela kufanele liye phambili ngokushelelayo, lijike kwesokunxele nakwesokudla lihambe kancane nhlangothi zombili, futhi lisheshise kancane phakathi nendawo. Qaphela kakhulu izinguquko zechibi elincibilikisiwe. Lapho ichibi elincibilikisiwe liba likhulu, i-weld seam iba banzi, noma i-welding seam iba yi-concave, ijubane lokushisela kufanele linyuswe noma umsinga wokushisela kufanele uncishiswe futhi. Lapho ukuhlanganiswa kwechibi elincibilikisiwe kungalungile futhi ucingo alukwazi ukuphakelwa, kuyadingeka ukunciphisa isivinini sokushisela noma ukwandisa i-welding current. Uma i-welding engezansi, amehlo kufanele agxile emaphethelweni angenalutho ezinhlangothini zombili ze-groove, nasemakhoneni amehlo. Ukukhanya kwe-peripheral ngakolunye uhlangothi lwe-slit, futhi unake ukuguqulwa kwezinye izindawo eziphakeme.
I-5) Ukucima i-arc: Uma i-arc icishwa ngokuqondile, kulula ukukhiqiza i-shrinkage cavity. Uma ithoshi yokushisela inesiqalisi se-arc, i-arc kufanele ivalwe ngezikhathi ezithile noma ilungiswe ibe namandla afanele e-arc crater current. I-arc iholelwa ohlangothini olulodwa lwe-groove, futhi akukho mgodi wokuncipha owenziwe. Uma kwenzeka imbobo yokuncipha, kufanele iphuculwe ngaphambi kokushiselwa.
Uma i-arc isendaweni ehlangene, i-arc kufanele igaywe ibe yi-bevel kuqala, bese i-welded phambili 10-20mm ngemva kokuba i-joint incibilike ngokugcwele, bese i-arc ivalwa kancane, futhi akukho mgodi wokuncipha ongenzeka. Ekukhiqizeni, kuvame ukubonakala ukuthi amalunga awahlotshisiwe abe yi-bevels, futhi isikhathi se-welding samalungu sinwetshwa ngokuqondile kumalunga. Lona umkhuba omubi kakhulu. Ngale ndlela, amalunga athambekele ekubeni yi-concave, amalunga angahlanganiswanga futhi uhlangothi olungemuva aluhlangene, okuzothinta ukubukeka kwesimo. Uma kuyi-alloy ephezulu Impahla nayo ijwayele ukuqhekeka.
