Indlela ukupheka Welding kagesi? Indlela ukupheka umthungo mpo zokushisela nge electric. Njengoba ukupheka electrowelded metal

Ngokuvamile kudingeka ukuxhuma izingxenye zensimbi noma izingxenyana imininingwane. Kunezindlela eziningana ukuze uthole umphumela oyifunayo. Ngokuvamile zezakhi zensimbi steel izingxenye esetshenziswa indlela zokushisela nge electric.

On ngalo kusekelwe?

Indlela ukupheka Welding kagesi? Ukuze uzwisise isimiso, kubalulekile ukukhumbula physics yekharikhulamu. Omunye izintambo umshini Welding exhunywe kwi-ucezu umsebenzi. On contact nale ebusweni kwenzeka i arc kagesi. Kumiswa iphuzu contact is ikhefu, okuyinto ugcwele metal oncibilikisiwe njengoba ihamba le electrode. Imiphetho izingxenye zensimbi zincibilike lapho izinga lokushisa omkhulu futhi uguqulwe ube ebumbene.

izindlela ukuthungela arc

Ukufunda ukupheka kwensimbi Welding kagesi, kubalulekile ukwazi okuthile indlela. Ibanga kanye lokushisa eliphezulu ishayela kagesi phakathi workpiece kanye electrode libizwa arc. Ezokwakha lezi zimiso, kukhona izindlela ezimbili:

• Esimweni sokuqala, lo electrode (ngokushesha ngokuthinta) "isiteleka ngokucijile" zensimbi, sengathi umdlalo. Arc isidingo Kuvezwe ukulondoloza, okuholela okufakiwe ku mm eziningana ebusweni ukusebenza metal.
• Esimeni sesibili, ithiphu electrode kuyadingeka ukuze ngokucijile badonsa workpiece.

I arc okuholela akufanele aphume aye. Uma kwakwenzeka, ngaphambi kokuvumela kagesi Welding ezivuzayo zigezwe ukususa esikalini. Ukuhluleka ukwenza njalo kuholela ekwakhekeni izimbobo.

Ukubaluleka samanje Welding

Ukubalwa amperage elihambisana electrode ukujiya ngeke practice ukuze ufunde indlela ukupheka Welding kagesi. Lapho enganele electrode lwamanje okunamathelayo, kanye arc - ucime. Ngezinye okusezingeni eliphezulu metal bamanje fafaza futhi ushise. Uma sisebenzisa transformer Welding, le electrode 1 mm uhambelana samanje 30-35 A. Iyasebenza Welding inverter electrode 3 mm uhambelana samanje 80 A. Uma amperage ukwanda, yensimbi kungenziwa ukusika.

I electrode ezisuselwe ukwakheka amakhemikhali metal. Kunezinhlobo eziningana filler impahla:

• steel;
• bimetal;
• inkatho yensimbi;
• zethusi;
• ngethusi.

Bonke futhi kwafakwa ilebuli Inkomba zesi elisho ukuthi ukushuba zensimbi nobulukhuni kohlobo ngalunye isetshenziswa.

Ukufunda ukupheka zokushisela nge electric, kubalulekile ukukhumbula ukuthi ukuze bathole eliphezulu welds electrode kumele luhambisane ukushuba we metal.

Welding flat uthayela

metal Izacile (1 kuya ku-3 mm) Butt wajoyina ngaphandle izikhala kanye izithasiselo, ekufezeni ofanayo ezinhle imiphetho ahambelana.

Ukuze amaphepha emalungeni kusebenta kahle mkhulu (3 kuya kwezingu-8 mm) imiphetho kumelwe inqunywe at engele kwesokudla. Shiya igebe phakathi amashidi 2 mm. I ukujiya impahla 8 mm ixhunywe ezimbili ngendlela Welding. Ukuze compounds mkhulu onqenqemeni izindiza bafa nge wotho.

Kuphi ukuqala ukufunda ukupheka yensimbi

Ukufunda indlela ukupheka kahle Welding kagesi, eziqala izinqubo eyisisekelo.

• izinto eliphekiwe zigxilé endaweni evundlile (ithebula Welding).
• Tack uwafake ku emaphethelweni kanye phakathi nendawo.
• Ukuze ozofakwa umnikazi kanye okufakiwe ezintsha unamathele ngocingo ingxenye yoquqaba.
• Ekuqaleni ukufeza lesifanele electrode emthambekeni (angaba ngu-75 degrees) e isiqondiso arc. Ngakho kubalulekile ukwenza ukunyakaza ezibonakala raking kwensimbi oncibilikisiwe ngesikhathi kugoqwa.
• Ukuphela electrode kumele kwenzeke maphakathi weld. Ngokusebenzisa ukugcinwa ukuthambekela amathonsi ngokulinganayo kuqhamuke njalo electrode ashisayo ngisho roller qualitative yakha i-weld.
• Emva lwaluyophola, workpiece kudingeka ukuba baphinde babe slag nge ebusweni workpiece.

Phakathi naleso sikhathi, njengoba nje okuhlangenwe nakho butholakala, le yaseZimbabwe izotholwa zonke made futhi amandla awo esinembile.

Indlela yokwenza umthungo mpo

Indlela ukupheka umthungo mpo zokushisela nge electric? Into esemqoka - ukuqala, kulandela zonke izincomo. Welding emalungeni mpo efanayo ukusebenza nendawo, nje kancane nzima. workpiece Prihvatyvayut ezindaweni ezimbili noma ezintathu. Khona-ke weld kuphela kusukela phansi kuze, ukunamathela iconsi ngu iconsi. Kancane kancane, yonke igebe ligcwele metal ashisayo. Kanjani ukufunda ukupheka nge kagesi? Umgomo ukuze uhlangane kokubili imiphetho ngu encibilika Welding yabo arc, kanyekanye ubhekiswe ukuba amaconsi metal kusukela isimo ketshezi kuze kube sekupheleni evuthayo we electrode.

Awukwazi yenza amathonsi umthungo, futhi lokho okubizwa ngokuthi "eziyisishiyagalombili", kodwa lokhu kungaba ukusingatha kuphela uchwepheshe abanolwazi. Ngakho, uma unentshisekelo ukwazi ukuthi ukufunda ukupheka umthungo mpo ngu Welding kagesi, kutuswa ukubheka umsebenzi UWelder abanolwazi, lalela iseluleko okuyinhloko. Futhi kuphela ke qala inqubo ngokwakho.

Indlela yokwenza elihle nelizinze ekhoneni umphetho

Kahle ukwenza okuthiwa "T-bar" omhlophe webhola akulula ukufunda ukupheka zokushisela nge electric. Lokhu ukusetshenziswa ahlangene uma ufuna ukubopha tincenye-engeli lehlukene. Metal izingxenye asethwe ukuze Welding trickled ku ekhoneni. Fixed "isikebhe" Welding izingxenye ubambe kusuka ezinhlangothini ezihlukene. Ngaphezu kwalokho, omunye emaphethelweni preform ophakamayo kancane ephakeme. Inqubo Welding kufanele kuqale emaphethelweni phansi. Kulokhu, kulandela ngokucophelela iziyalezo zendlela ukupheka kahle Welding kagesi, izinga weld kungenziwa ngcono kakhulu.

Indlela engcono kakhulu ukusebenzisa umshini Welding

1. welders Old kokuba elawulwa igebe kazibuthe, okuvumela ukuba ulungise amandla wamanje, - transformer. Zikhona ongakhetha eziningi onobuhle dimmers futhi ESIKLINYAYO ezengeziwe ohlangothini samabanga aphansi noma we transformer.
2. Inverter amayunithi - kudivayisi Welding zanamuhla. Ukusebenza kusukela okusezingeni eliphezulu imvamisa transformer amayunithi enjalo unamahlangothi ezincane nesisindo ongaphakeme. Ngo mishini, kungase kushintshwe izindlela ngokushelela Welding. kulungiselelwa Isibongo kufanele kwenziwe ngokucophelela, ngaphandle kwalokho umshini kusheshe kungalimala.

Izindlela kwabashiselayo amapayipi

In the ukungabikho isipiliyoni ukufunda indlela ukupheka electrofusion ipayipi, kungcono kwi metal obukhulu. Kuye ukushuba odongeni kwenza maqembu amaningi. Multilayer Welding ngcono izakhiwo mechanical okuholela uxhumano weld buyaqina.

Ekuqaleni ashiselwe isigamu-indandatho kwelinye direction ke - in the yesibili. Esikhathini indlela inkomba weld "phansi" 4 mm electrode nokuba sputtering organic. Lapho arc iDemo, sithembele umfanekiso "hood", amabhokisi usethe-top kukhona oscillations encane lateral.

Lapho besebenza ngokuvumelana indlela "ezinqala" ngokucijile ukunciphisa ijubane. Izikhombo electrode ka oscillations transverse ukwenza 3-5 mm.

Lapho Welding ezakhiwe amapayipi okokuqala kudingekile ukulungisa uphinde uhlele zonke izinto etafuleni Welding noma ebhentshini. Base ottsentrovyvayut futhi bebambisana ukufeza oyifunayo Welding igebe. Kuvuna emalungeni prihvatyvayut phakathi kwazo.

Inqawe nge ubukhulu encane exhunywe Welding okuqhubekayo ngenhloso ububanzi esikhulu - ngendlela discontinuous. Emva kokuphothulwa kwazo zonke izinqubo of Welding umsebenzi metal Kwamanzi bahlanza of isikali, lesi sifutho eqina slag. Olwenziwe wokuhlola ezibukwayo ukuthola ngokuhlaziya noma kokusha ngokusebenzisa, kusale asemigodini noma ikhule ezimbotsheni. Ephambi kwezinduna umphetho izindawo kahle ashiselwe wenza sokubuyiselwa.

Ukuze uphephe siqu okudingeka usebenzele ngesikhathi Welding Suede amagilavu kanye amagilavu, a UWelder efake isifihla-buso e ngoseyili noma isikhumba esindayo izicathulo izembatho ukotini. Kuyadingeka eduze kufanele mlilo noma isitsha amanzi.
