1. Irekhodi langempela le-mirror welding
I-Mirror welding iwubuchwepheshe bokusebenza kwe-welding esekelwe kumgomo wokuthwebula isibuko futhi isebenzisa ukubuka okusizwa isibuko ukulawula inqubo yokushisela. Isetshenziselwa ikakhulukazi ukushisela ama-welds angakwazi ukubonwa ngokuqondile ngenxa yesimo sokushisela esincane.
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nabasika - Imboni Yokushisela & Cutting yase-China & Suppliers (xinfatools.com)
Isikhundla esimisiwe sesibuko ngokuvamile sinezidingo ezimbili. Okokuqala, kufanele kube lula ngeso lenyama ukubona isimo sechibi elincibilikisiwe ngokusebenzisa ukubonakaliswa kwesibuko. Okwesibili, akumele kuthinte isikhundla se-argon arc welding gun kanye nokuhamba nokushwibeka kwesibhamu sokushisela ngesikhathi senqubo yokushisela. Ibanga phakathi kwesibuko kanye ne-weld seam Indawo ehlobene yemigqa yamashubhu iyalungiswa kuye ngesikhala.
2. Ukulungiselela ngaphambi kokushisela
(1) Igebe lokushisela indawo kufanele lilawulwe ngokuqinile, ngokuvamile libe ngu-2.5 ~ 3.0 mm. Indawo yokuthungatha indawo yokuthungela kufanele ibe ngaphambili kwepayipi.
(2) Ukubekwa kwelensi: Beka ilensi endaweni lapho ukushisela kuqala khona ngendlela eqondile, futhi usebenzise isibhamu sokushisela ukulinganisa umzila ngesikhathi sokushisela ukuze ulungise ibanga kanye ne-engeli yelensi ukuze ilensi ibe sesimweni esingcono kakhulu ukubonwa kwe-welding.
(3) Hlola ukuthi izinga lokugeleza kwegesi ye-argon ngokuvamile lingu-8~9 L/min, ubude besandiso se-electrode ye-tungsten bungu-3~4 mm, futhi ukugoba kwe-arc yocingo lokushisela kulungiselelwe kusengaphambili.
3. Ukuhlaziywa kobunzima ekushiseni kwesibuko
(1) Ukuthwebula esibukweni kuwukubonakaliswa kwesithombe. Ngesikhathi sokusebenza kwe-welding, ukusebenza okubonwe ngumshiseli ohlangothini lwe-radial yomlomo wepayipi kuphambene nesiqondiso sangempela. Phakathi nenqubo yokushisela, kulula ukondla ucingo echibini elincibilikisiwe esibukweni. , okuthinta ukushisela okuvamile.
Ngakho-ke, ukujikijela kwe-arc yokushisela kanye nokunyakaza kokugcwalisa ucingo kunzima ukuhambisana, ukuhambisana, nokuhleleka, okungabangela kalula ukuthi i-arc ibe yinde kakhulu, i-tungsten iphonswe, ukugcwaliswa kwezintambo kunganele, futhi ukuphela kwentambo yokushisela ukuze ishayisane ne-electrode ye-tungsten.
(2) I-lateral swing kanye nokunyakaza kwe-arc welding akuguquki ngokwanele, okungaholela kalula ekungeneni okungaphelele kwempande, i-concavity, ukungabi khona kwe-fusion, i-undercutting, nokwakheka okungalungile. Uma ijubane lokushisela lihamba kancane, amaphutha anjengama-pores angenzeka kalula.
(3) Lapho ubuka ichibi elincibilikisiwe esibukweni, ukukhanya kwe-arc kunamandla kakhulu futhi kunzima ukubona induku ye-tungsten ngokucacile. Lapho uphakela ucingo, kulula ukubangela ukuthi ucingo lokushisela lushayisane nentonga ye-tungsten, lukhubaze ichopho lwenduku ye-tungsten, luthinte ukuzinza kwe-arc, futhi lubangele kalula amaphutha njengokufakwa kwe-tungsten. .
(4) Umthungo wokushisela obonwa esibukweni uyisithombe esiyisicaba. Umphumela wezinhlangothi ezintathu ze-weld seam esibukweni awunamandla, futhi izithombe zesibuko zokukhanya kwe-arc kanye nedamu elincibilikisiwe zibekwe phezu komunye nomunye. Ukukhanya kwe-arc kunamandla kakhulu, futhi kunzima ukuhlukanisa ngokucacile ichibi elincibilikisiwe, ngakho-ke i-weld seam Ukulawulwa kokuqina nokuqondile kuzothinta ngqo ikhwalithi yokubunjwa kwe-welding seam.
4. Indlela yokusebenza kwe-Mirror welding
(1) Ukushisela ungqimba oluyisisekelo
a.Indlela yocingo lwangaphakathi
Beka isibhamu se-welding endaweni lapho i-welding iqala ukushaya i-arc, futhi uhambise ucingo lwe-welding ngokusebenzisa igebe le-groove ngaphambili ukuya endaweni evuthayo ye-arc ngemuva. Bheka ukwakheka kwempande ngeso lenyama, futhi ubheke ukuvutha kwe-arc nokubukeka kwakheka ku-lens ngezikhathi ezithile. . Sebenzisa indlela "ehamba kancane emibili neyodwa esheshayo" ukuze usebenzise isibhamu esishiselayo.
Lawula ukujiya kwesendlalelo sesisekelo ku-2.5~3.0 mm. Weld kusukela 6 ezimpondweni kuya 9 ezimpondweni, bese weld kusukela 6 ezimpondweni kuya 3 ezimpondweni. Gcwalisa i-welding ye-base layer ngokulandelana okuboniswe kuMfanekiso 2.
b.Indlela kasilika yangaphandle
Okokuqala, lungiselela kusengaphambili i-arc ngenani le-welding wire, bese ulungisa umlomo wesibhamu sokushisela kubhontshisi we-pipe weld nge-engeli engu-60 °, qala i-arc, futhi unake isimo sokudla kocingo se-arc nechibi elincibilikisiwe. kulens.
Ucingo lungaphakelwa ngokuqhubekayo noma ngokuphazanyiswa kwe-arc. Ukubonakaliswa kwelensi kungadukisa ukusebenza kalula: ngokwesibonelo, kunzima ukuhlukanisa phakathi kwentambo yokushisela yangempela kanye nentambo yokushisela ebonakala ku-lens, okungaholela kalula ekuphakeleni ngocingo okwanele, izinga lokushisa elincibilikisiwe ngokweqile, kanye nokulimala i-tungsten. Kakhulu, amaphutha anjengama-pores nama-depressions avela.
Ngakho-ke, ukusebenza kuwukuzinikela ekuboniseni isibuko, futhi ngokuqaphela uxhume i-arc curvature yocingo lokushisela emseleni ukuze wondle ucingo ngokulinganayo. Isibhamu sokushisela sisetshenziswa kusetshenziswa indlela "emibili kancane kancane futhi eyodwa esheshayo", futhi i-angle yesibhamu sokushisela ilungiswa ngokusho kwe-arc ku-lens.
Gwema ukutshekisa isibhamu sokushisela kakhulu, okwenza i-arc ibe yinde kakhulu futhi ungqimba oluyisisekelo lube lukhulu kakhulu, ukuvimbela amaphutha njengokungena okungaphelele. Lapho i-welding iphakathi kwehora lesi-8 kuya kwelesi-9, ingxenye ye-arc yangempela ingabonakala, futhi ukusebenza kungahlanganiswa nesimo sangempela kanye nesibuko esiphezulu.
Gcwalisa i-1/4 ye-weld yomlomo wepayipi bese uqala ukushisela isibuko kwenye 1/4 ye-weld. Ijoyinti endaweni yehora lesi-6 ingenye yemisebenzi ebalulekile yokushisela isibuko, futhi ukukhubazeka kungenzeka kakhulu ngesikhathi sokusebenza okuphambene.
Ngesikhathi sokusebenza, ukuqinisekisa ikhwalithi yokuhlangana, i-arc kufanele ithungelwe cishe ku-8 ~ 10 mm we-weld yangaphambili yejoyinti, bese i-arc kufanele ilethwe kancane kancane ekuhlanganyeleni kwe-weld yangaphambili ngehora lesi-6. . Uma kwakhiwa ichibi elincibilikisiwe endaweni ehlangene Bese wengeza ucingo lokushisela ukuze usebenze ngokujwayelekile kwesibuko.
Ekugcineni, qedela i-primer welding ohlangothini lwangaphambili (i-non-mirror welding) ngokuvumelana nokulandelana ku-Figure 2, futhi ukuvala uphawu kuqediwe.
(2) Ukushisela ungqimba lwekhava
1) Ukuhlaziywa kobunzima
Ngenxa yokuthi isikhundla se-weld esibukweni siphambene nesento yangempela, kulula ukubangela ama-undercuts, imiphetho engahlanganisiwe ye-grooves, izendlalelo zangaphakathi ezingahlanganisiwe, ama-pores, noma ukulimala kwe-electrode ye-tungsten ngesikhathi sokusebenza.
2) Izidingo zokusebenza kwe-welding
Ngaphambi kokushisela, i-trajectory yesibhamu sokushisela kufanele ifaniswe, futhi i-angle ye-lens kanye ne-arc curvature yenani elilungiselelwe ngaphambilini le-welding wire kufanele ilungiswe.
Ngesikhathi sokusebenza kwe-welding, kufanele uqale uqondanise umlomo wesibhamu sokushisela endaweni yehora lesi-6 se-groove nge-engeli engu-60 ° yokushisa kwe-arc. Ngemuva kokushisa kwangaphambili, ngokukhanya kwe-arc ukukhanya, nweba intambo yokushisela egobile ngaphambili ukusuka ohlangothini lwepayipi ukuya endaweni evuthayo ye-arc kulens. Isikhundla, i-feed wire. Indlela engcono kakhulu yokuphakela ucingo ukuxhuma intambo yokushisela ene-arc curvature kumthungo wokushisela wepayipi, kancane wondle ucingo ngokuqhubekayo nangokulinganayo ungene echibini elincibilikisiwe, futhi ubuke ukukhula konqenqema lomthungo wokushisela kanye noshintsho amaconsi ancibilikisiwe ku-lens. inqubo kanye nobude be-arc bethiphu ye-electrode ye-tungsten,
Ngokwendlela yokushisela “okubili okunensayo nokukodwa kuyashesha”, thuthela endaweni yehora lesi-9 endaweni yesibuko ukuze uqedele ukushisela kwekhava engu-1/4 bese ucisha i-arc. Bese uhambisa ilensi kwenye i-1/4 ye-weld yangemuva ukuze ulungise ukulinganisa kwe-trajectory kanye nokulungisa. Ukusebenza okungalungile kwe-interface kumaphuzu angu-6 kuzophinde kubangele ukukhubazeka kwe-welding, futhi kuyisigaba esiminyene lapho kuvela khona amaphutha.
Kungcono ukuqala ukushisisa i-arc ngaphambili ngehora lesi-6. Lapho ilunga lincibilika libe yichibi elincibilikisiwe, engeza ucingo lokushisela ukuze wenze umsebenzi ojwayelekile wokushisela isibuko. Naka isimo sokuncibilika konqenqema bese ulandela indlela ye-1/4 yokuqala. Sebenza kuze kuphume i-arc ngehora lesi-3 futhi ime.
Bese weld ingxenye ashiselwe ngokuvumelana nezindlela ezivamile ukuqedela isembozo ungqimba Welding of lonke ipayipi.
5. Izinyathelo zokuphepha
①Amakhono okubeka esibuko abaluleke kakhulu. Uma i-lens iqhela entweni yangempela noma lapho ihambisana kancane nento yangempela, kulapho ukunemba okukhulu kokusebenza kuzoba khona;
