Lits'oants'o tse leshome tsa li-welding, XINFA e tla hlahisa mekhoa e leshome e tloaelehileng ea li-welding, lipopae tse hlakileng haholo, ha re ithuteng hammoho!
1.Electrode arc welding
Electrode arc welding ke e 'ngoe ea litsebo tsa mantlha tseo li-welders li li tsebang. Haeba litsebo li sa sebetse hantle, ho tla ba le mefokolo e fapa-fapaneng seam e cheselitsoeng, joalokaha ho bontšitsoe videong e latelang ea ho ruta.
2.Ho tjheseletsa arc ka tlasa metsi
Submerged arc welding ke mokhoa oa welding o sebelisang arc e le mohloli oa mocheso. Ka lebaka la ho kenella ho tebileng ha li-arc welding, tlhahiso le boleng ba welding li ntle: ka lebaka la tšireletso ea slag, tšepe e qhibilihisitsoeng ha e kopane le moea, 'me tekanyo ea ts'ebetso ea mochine e phahame, kahoo e loketse. bakeng sa ho cheselletsa li-welds tse telele tsa lipoleiti tse mahareng le tse teteaneng.
3.Argon arc welding
XINFA e arolelana le uena litemoso tse 'maloa bakeng sa welding ea argon arc:
(1) Nale ea tungsten e lokela ho leotsoa khafetsa. Haeba e le botsoa, ea hona joale e ke ke ea tsepamisa mohopolo le ho thunya.
(2) Haeba sebaka se pakeng tsa nale ea tungsten le seam ea welding e haufi, e tla khomarela hammoho, haeba e le hōle, lebone la arc le tla thunya, 'me hang ha le thunya, le tla chesa, lesela la tungsten le tla fetoha lefatla. , 'me mahlaseli ka boeona a boetse a matla. Ho molemo ho ba haufi.
3 Sena ha se mochini oa tjheseletsa o itirisang o nang le motsamao oa othomathike le ho fepa ka terata ka boiketsetso.
(4) Ho fepa terata, e na le letsoho la letsoho. Mohala oa tjheseletsa oa boemo bo holimo o khaoloa ho tloha botong ea 304 ka mochini o kuta. U se ke ua e reka ka bongata. Ha e le hantle, u ka fumana tse ntle libakeng tse ngata.
(5) Leka ho sebetsa tlas'a maemo a kenang moea, o nang le liatlana tsa letlalo, liaparo, le mask a itšebetsang a fifatsang.
(6) Hlooho ea ceramic ea toche ea welding e lokela ho sireletsoa ho leseli la arc, haholo-holo, mohatla oa toche ea welding e lokela ho ba haufi ka hohle kamoo ho ka khonehang sefahlehong sa hau.
(7) Haeba u ka ba le intuition le hunch mabapi le thempereichara, boholo, le switjha ketso ea letamo ho qhibilihisoa, u setsebi se seholo sa theknishiene.
(8) Leka ho sebelisa linale tsa tungsten tse tšehla kapa tse tšoeu, tse hlokang tsebo e phahameng ea matsoho.
4.Ho cheselletsa khase
Khase tjheseletsa (lebitso le feletseng: oksijene mafura khase tjheseletsa, khutsufatso: OFW) ke ho sebelisa lelakabe ho futhumatsa tšepe le terata tjheseletsa ka kopanelo ea workpiece tšepe ho qhibiliha ho finyella morero oa tjheseletsa. Ligase tse tukang tse sebelisoang ka tloaelo haholo ke acetylene, liquefied petroleum gas le hydrogen, joalo-joalo, 'me khase e sebelisoang hangata e tšehetsang ho tuka ke oksijene.
5.Laser welding
Laser welding ke mokhoa o sebetsang hantle le o nepahetseng oa ho tjheseletsa o sebelisang lebone la laser le nang le matla a phahameng joalo ka mohloli oa mocheso. Laser welding ke e 'ngoe ea likarolo tsa bohlokoa tsa ts'ebeliso ea theknoloji ea laser material processing. Lilemong tsa bo-1970, e ne e sebelisoa haholo-holo bakeng sa ho cheselletsa thepa e nang le marako a tšesaane le ho cheselletsa ka lebelo le tlaase. The tjheseletsa tshebetso ke mocheso conduction, ke hore, laser mahlaseli futhumatsang holim'a workpiece, 'me mocheso holim'a diffuses ho ea ka hare ka mocheso conduction. Ka ho laola bophara, matla, matla a tlhōrō le ho pheta-pheta maqhubu a laser pulse le likarolo tse ling ho qhibilihisa workpiece le ho theha letamo le khethehileng le qhibilihisitsoeng.
6.Carbon dioxide e sirelelitsoe welding
Basebelisi ba bang ba hloahloa ba nahana hore carbon dioxide shielded welding ke eona e bonolo ka ho fetisisa, hobane ke eona e bonolo ka ho fetisisa ho e sebelisa le ho ithuta. Ka kakaretso, haeba moithuti ea e-s'o ka a kopana le welding, haeba monghali a mo ruta lihora tse peli kapa tse tharo, ha e le hantle, ho ka sebelisoa welding e bonolo.
Ho na le lintlha tse 'maloa tsa bohlokoa tsa ho ithuta carbon dioxide shielded welding: matsoho a tsitsitseng, hona joale le motlakase, lebelo le laoloang, boitšisinyo, bo ka sebelisoang ka ho shebella livideo tse ngata, ebe joale o tseba tatellano ea tjheseletsa, eo ha e le hantle e ka sebetsanang le ho feta halofo ea mosebetsi o ile a kopa.
7.Friction welding
Friction welding e bua ka mokhoa oa ho tjheseletsa ka ho sebelisa mocheso o hlahisoang ke khohlano ea sebaka sa ho ikopanya sa workpiece e le mohloli oa mocheso ho etsa hore workpiece e be le deformation ea polasetiki tlas'a khatello.
Tlas'a ketso ea khatello, tlas'a ketso ea khatello e sa khaotseng kapa e ntseng e eketseha le torque, motsamao o lekanyelitsoeng pakeng tsa marang-rang a ho kopana le tjheseletsa o sebelisetsoa ho hlahisa mocheso oa khohlano le mocheso oa polasetiki holim'a likhohlano le libaka tse haufi le eona, e le hore mocheso oa libaka tse potolohileng li nyolohela ho Mocheso oa mocheso o haufi le empa ka kakaretso o le tlase ho feta ntlha ea ho qhibiliha, ho hanyetsa deformation ea thepa ho fokotsehile, polasetiki e ntlafatsoa, 'me filimi ea oxide e holim'a sebopeho e robehile. Mokhoa o tiileng-state tjheseletsa o fihlelang welding.
friction welding hangata e na le mehato e mene e latelang: (1) phetoho ea matla a mochine hore e be matla a mocheso; (2) deformation polasetiki ea thepa; (3) ho etsa khatello tlas'a thermoplasticity; (4) phallo ea limolek'hule le ho recrystallization.
8.Ultrasonic welding
Ultrasonic welding ke tšebeliso ea maqhubu a sisinyehang a phahameng haholo ho fetisetsa bokaholimo ba lintho tse peli tse lokelang ho chesetsoa. Tlas'a khatello, bokaholimo ba lintho tse peli bo hohlana ho bopa ho kopana lipakeng tsa masela a limolek'hule. Likarolo tse ka sehloohong tsa ultrasonic welding system li kenyelletsa ultrasonic jenereithara / transducer / lenaka / welding hlooho triplet / hlobo le foreimi.
9.Soldering
Brazing ke ho sebelisa thepa ea tšepe e nang le ntlha e tlaase ea ho qhibiliha ho feta tšepe ea motheo e le solder, futhumatsa weldment le solder ho mocheso o phahameng ho feta ntlha ea ho qhibiliha ea solder le ka tlaase ho mocheso o qhibilihang oa tšepe ea motheo, sebelisa mokelikeli. solder ho kolobisa tšepe ea motheo, ho tlatsa lekhalo pakeng tsa manonyeletso le Mokhoa oa ho kopanya ka tšepe ea motheo ho hlokomela khokahanyo ea weldment. Deformation ea brazing e nyane, 'me lenonyeletso le boreleli ebile le ntle. E loketse ho tjheseletsa ka nepo, e rarahaneng le likarolo tse entsoeng ka lisebelisoa tse fapaneng, joalo ka lipoleiti tsa sebopeho sa khekhe ea linotsi, likhaba tsa turbine, lisebelisoa tse thata tsa alloy le liboto tsa potoloho tse hatisitsoeng. Ho ipapisitse le mocheso oa welding, brazing e ka aroloa ka mekhahlelo e 'meli. Haeba mocheso oa mocheso oa ho futhumatsa o ka tlase ho 450 ° C, o bitsoa soft soldering, 'me haeba o phahametse 450 ° C, o bitsoa hard brazing.
