Umqondo ojwayelekile kanye nokuphepha kwendlela yama-welders kagesi, izinqubo zokusebenza zimi kanje:
1. Kufanele wazi kahle ulwazi olujwayelekile lukagesi, ulandele imithetho evamile yokuphepha yabashiseli, futhi ujwayelane nobuchwepheshe bokucisha umlilo, usizo lokuqala lokushaqeka kukagesi nezindlela zokuphefumula zokwenziwa.
2. Ngaphambi komsebenzi, hlola ukuthi ulayini wamandla, ulayini wokuhola kanye nephoyinti lokuxhuma ngalinye lomshini wokushisela usesimweni esihle. Umugqa owela umgwaqo kufanele uphakanyiswe noma umbozwe; kuhle.
3. Ukushisela emoyeni ovulekile akuvunyelwe ngezinsuku zemvula. Lapho usebenza ezindaweni ezimanzi, kufanele ume endaweni lapho izinto zokuvikela zibekwe khona futhi ugqoke izicathulo zokuvikela.
4. I-wiring noma ukuhlolwa komshini wokushisela ohambahambayo kusuka kugridi yamandla, kanye nokubeka phansi kufanele kwenziwe ngabasebenza ngogesi.
5. Lapho ucindezela inkinobho yommese, umzimba kufanele utshekiswe kancane, bese umshini wokushisela kagesi kufanele uvule ngemva kokuphusha okukodwa; umshini wokushisela kagesi kufanele ucishwe ngaphambi kokuba inkinobho yommese wamandla ikhishwe.
6. Ukuhambisa isikhundla somshini wokushisela, misa umshini bese usika amandla kuqala; uma ima kungazelelwe ngesikhathi sokushisela, cisha umshini wokushisela ngokushesha.
7. Uma ushisela ezindaweni eziminyene, kufanele kufakwe umgoqo ukuze kuvinjwe ukukhanya kwe-arc. Uma singekho isithiyo, izisebenzi ezizungezile kufanele zikhunjuzwe ukuthi zingabheki ngqo ekukhanyeni kwe-arc.
8. Gqoka amagilavu lapho ushintsha ama-electrode, futhi unganciki umzimba wakho kuma- iron plate noma ezinye izinto ezihambisayo. Gqoka izibuko zokuzivikela lapho ushaya i-slag.
9. Lapho ushisela izinto zensimbi ezingenayo insimbi, ukungena komoya kanye nokukhipha ubuthi kufanele kuqiniswe, futhi imaski yegesi yokuhlunga kufanele isetshenziswe uma kunesidingo.
10. Lapho ulungisa amapayipi egesi noma ukushisela lapho kuvuza khona igesi, kufanele wazise igalaji likaphethiloli, ukuvikela umlilo, nomnyango wezobuchwepheshe bokuphepha kusenesikhathi, futhi usebenze kuphela ngemva kokuthola imvume. .
11. Ngemuva kokuthi umsebenzi usuphelile, umshini wokushisela kufanele uvaliwe, bese ukunikezwa kwamandla kufanele kunqanyulwe.
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)
Izinqubo zokusebenza zomshini wokushisela ovikelwe ngegesi
1. Ngaphambi komsebenzi
1. Ukubekwa phansi komshini wokushisela kanye ne-heater kumele kube okuthembekile, futhi ukugxilwa kwethoshi lokushisela kufanele kube kuhle.
2. Amasilinda egesi noma ama-valve egesi yamapayipi kufanele aphelele, futhi izivalo kufanele zivalwe lapho uphatha amasilinda egesi.
3. Uhla lokuguquguquka kwamandla kagesi akumele ludlule u-±10% wevolthi yokufaka elinganiselwe ngaphambi kokusetshenziswa.
4. Izinsimbi ezihlukahlukene namamitha emshini wokushisela kufanele aphelele futhi abe sesimweni esihle.
5. Izesekeli zamathuluzi ziphelele futhi zisesimweni esihle.
6 Indawo yokusebenza kufanele ihlangabezane nezidingo.
7 Hlola ukuthi iphansi lomshini wokushisela lihlanzekile futhi alinayo imfucumfucu, futhi uvimbele ngokuqinile ukuba khona kwezinhlayiya zensimbi.
Okwesibili, emsebenzini
1. Ngemva kokudlulisa ukuhlolwa kwangaphambi kokushintsha, qala uvule inkinobho enkulu yamandla, isenzo kufanele sisheshe, bese uvula inkinobho yokulawula amandla. Ukukhanya okuluhlaza kusho ukuthi umshini wokushisela ujwayelekile.
2. Hlola ukuthi ingabe i-fan yokupholisa isebenza ngokujwayelekile yini nokuthi indlela yomoya ayiphazamiseki yini. Ungasebenzisi idivayisi ngaphandle kokupholisa.
3. Vula inkinobho yokubona igesi, vula i-valve yegesi, futhi uhlole ukuthi i-valve yegesi isesimweni esihle yini; lungisa ukugeleza kwegesi ku-10? /FONT>20 amalitha/min.
4. Xhuma ingxenye yokudlulisela yomshini wokuphakela ngocingo, hlola ukuthi isivinini sokuphakela ngocingo sifana yini, futhi usilungise sibe nenani elifanele.
5. Xhuma isifunda sokushisela esiyinhloko sokuhlola ukushisela. Lungisa ingcindezi yamanje, i-voltage, isondo lokuphakelayo kwezintambo kanye nebanga phakathi kwethiphu yokushisela nensimbi eyisisekelo ngokuya ngezidingo zenqubo yokushisela, futhi ubheke ikhwalithi ye-weld nganoma yisiphi isikhathi. Lilungise futhi ulilungise libe sesimweni esingcono.
6. Ukushisela kungenziwa kuphela ngemva kokuba konke sekujwayelekile.
7. Izinto ezilandelayo kufanele zinakwe uma usebenzisa ithoshi lokushisela:
① Ekusetshenzisweni okuqhubekayo, umjikelezo wokushisela kanye nomsebenzi wethoshi lokushisela kufanele ulawulwe ngaphakathi kwebanga elishiwo kuthebula lokulinganisa lawo wonke amathoshi okushisela.
②Ukuze kunwetshwe impilo yesevisi yombhobho kanye nethiphu yokuxhumana, ungqimba lwe-ejenti evimbela ukuvimbela kufanele lusetshenziswe ngaphambi kokusetshenziswa ukuze luvinjwe ukuthi lunganamatheli ku-spatter wokushisela.
③Imbobo kufanele ihlanzwe njalo ukuze kuvinjwe ukuphuma komoya ekuvinjweni yi-spatter, ukuze kuqinisekiswe ukugeleza okushelelayo kwendlela yegesi kanye nokuvikela ukujikeleza okufushane komthombo wamandla wokushisela ekulimazini izingxenye zikagesi ngaphakathi komshini. Ithiphu yokuxhumana kufanele ihlolwe njalo ngesikhathi sokusetshenziswa. Shintsha ngokushesha uma igugile noma ivalekile.
④ Ngemuva kokuthi ithoshi lokushisela selisetshenzisiwe, kufanele libekwe endaweni ethembekile, futhi kwenqatshelwe ukulibeka endaweni yokushisela.
8. Naka isimo sokudlulisa ucingo lokushisela nganoma yisiphi isikhathi phakathi nomsebenzi. Isondo eliqinile akufanele lixege kakhulu noma liqine kakhulu, ishubhu lesondo lokushisela akufanele libe nokugoba okucijile, kanti i-radius encane yokugoba kufanele ibe>> 300 mm.
9. Kuvinjelwe ngokuphelele ukusebenzisa abalandeli endaweni yokushisela ukuze kuqinisekiswe umphumela wokuvikela wegesi.
10. Lapho ushiya okuthunyelwe, isifunda segesi kanye nesifunda kufanele sivalwe, futhi amandla anganqunywa ngaphambi kokuhamba.
3. Ngemva komsebenzi
1. Vala i-air circuit kanye nesekethe, unqamule ugesi, uhlanze indawo yokusebenza, uhlole futhi ucime izinhlansi kusayithi, futhi ubeke izesekeli zamathuluzi endaweni ecacisiwe.
2. Yenza umsebenzi omuhle ekunakekeleni umshini wokushisela ngokuvumelana nemithetho yesondlo.
3. Yenza umsebenzi omuhle emsebenzini wamashifu.
Izinqubo zokusebenza ze-Argon arc welding
1. Ngaphambi kwe-welding, ibhodlela legesi le-argon kufanele lilungiswe kuqala, futhi i-argon gas flow meter kufanele ifakwe ebhodleleni, bese ipayipi yegesi kufanele ixhunywe emgodini wokungena emoyeni ephaneli elingemuva lomshini wokushisela. Ukuxhuma kufanele kuqine ukuvimbela ukuvuza komoya.
2. Xhuma ithoshi yokushisela i-argon arc, isixhumi segesi, isixhumi esisheshayo sekhebula nesixhumi sokulawula kumasokhethi ahambisanayo omshini wokushisela ngokulandelana. I-workpiece ixhunywe kutheminali ethi "+" ngocingo oluphansi lokushisela.
3. Xhuma intambo yamandla yomshini wokushisela bese uhlola ukuthi isisekelo sithembekile yini.
4. Ngemva kokuxhuma ugesi, khetha i-AC argon arc welding noma i-DC argon arc welding ngokuvumelana nezidingo zokushisela, bese uhambisa inkinobho yokushintsha umugqa kanye nokulawula ukushintsha ukushintshela ku-AC (AC) noma i-DC (DC) igiya. Qaphela: Amaswishi amabili kufanele asetshenziswe ngokuhambisanayo.
5. Setha inkinobho yokushintsha imodi yokushisela endaweni ye-"argon arc".
6. Vula i-argon gas cylinder kanye ne-flow meter, bese udonsa inkinobho yegesi yokuhlola endaweni "yokuhlola igesi". Ngalesi sikhathi, igesi iphuma kuthoshi lokushisela. Ngemuva kokulungisa ukugeleza komoya, donsa igesi yokuhlola kanye ne-welding switch endaweni "ye-welding".
7. Ubukhulu be-welding current bungalungiswa ne-handwheel yokulungiswa kwamanje, i-current iyancipha uma ijikeleziswa ngokwewashi, futhi ukwanda kwamanje uma ijikeleziswa ngokuphambene newashi. Ububanzi bamanje bokulungisa bungakhawulwa ukushintsha kosayizi wamanje.
8. Khetha induku ye-tungsten efanele kanye ne-chuck ehambisanayo, bese ugaya induku ye-tungsten ibe yi-taper efanelekile, bese uyifake kuthoshi lokushisela. Ngemva kokuba umsebenzi ongenhla usuqediwe, cindezela inkinobho yethoshi yokushisela ukuze uqale ukushisela.
