Indlela ukupheka ilungelo semiautomatic? Indlela ukupheka idivayisi semiautomatic ngaphandle gas?
Zokushisela ingenye izigaba ezibucayi kakhulu kokubili ukukhiqizwa yezimboni kanye namabhizinisi amancane. Akufanele sibakhohlwe mayelana ukubaluleka kwabo kwe-aspect ngisho banal ukulimela ukuziphilisa. Kuzo zonke lezi zimo, ikhwalithi Welding ngokuvamile akuxhomekile nje kuphela esimweni nokwethenjelwa tekusebenta umkhiqizo osuphelile, kodwa futhi ukuphepha abantu ukuyisebenzisa.
imiqondo Jikelele
Ngokuvamile, le nqubo ingenye izinhlobo eziningi zakudala arc Welding. Njengoba ukumelana layo liphakeme kakhulu kunaleyo electrode, bakha ingxenye enkulu yabamemezeli amandla ezikhishwe esikhaleni emhlabeni arc elicibilikile ebusweni Weldable kanye electrode ngokwayo, kanjalo zakha isimiso okuthiwa okugeza eziphothene.
Emva uxhumano selupholile futhi zakristallizuetsya kwakhiwa weld okuyinto esigabeni samanje yentuthuko kwezobuchwepheshe kubhekwa indlela enokwethenjelwa kakhulu metal ngokuhlanganyela izingxenye.
Izimiso eziyisisekelo Welding semiautomatic
Ngokungafani classic arc Welding, enqubeni kubhekwe busa unezinto ezimbili: (wire Welding) electrode futhi igesi engaxubani namakhemikhali, esivikela pool weld. Ngaphambi ukupheka semi-automatic, lona wamuva efiselekayo kakhulu ukuthenga izinto eziningi ezanele.
Izimo yokugcina kubaluleke kakhulu. Okokuqala, uma kungenjalo kwakhiwa amanyela kakhulu, futhi surface uxhumano iba neze: Iqiniso ukuthi weld uzame zonke izindlela ukuba ngigweme nokuxhumana imvelo ezungeze umoya-mpilo ngesikhathi ukusebenza. Okwesibili, e-metal weld kukhona omningi oxides okuyinto esilimaza izinga joint esiphelele. Yingakho kule qiniso eziphothene kabanzi argon ne-carbon dioxide.
Incazelo kwendikimba yenqubo Welding
Phakathi Welding, electrode (wire) sidlula umlomo wombhobho sikaphalafini, lapho elicibilikile ngenxa lokushisa eliphezulu we arc. Kusukela wire Welding sidla ngokuqhubekayo, kungenzeka ukuba sifinyelele izinga njalo futhi inqubo ijubane. I isiqondiso nesivinini kukhethwe ngesandla. Landela yokudla okuqhubekayo we electrode futhi uwela UWelder. Esikhathini ngezigaba international, le nqubo ubizwa ngokuthi GMAW (igesi metal arc Welding). Hlukanisa Welding i igesi engaxubani namakhemikhali noma asebenzayo.
Lesi sakamuva isetshenziswa ikakhulukazi ezimweni lapho izakhiwo zensimbi ayikuvumeli ukufeza ezinye izici okhethekile weld. Nakhu ukuthi ukupheka semiautomatic.
Yini edingekayo ukuze lokhu imishini?
Le kit kuzomele sifake imishini ngokwayo UWelder weld umthombo zamanje, wire Element, kanye negesi isilinda. Amadivayisi yalolu hlobo ayatholakala ezinguqulweni ephathekayo, kanye chassis ukusetshenziswa emkhakheni. Ngakho ukufunda indlela ubilise kudivayisi semiautomatic yalolu hlobo kunzima emsebenzini avunyelwe labo kuphela kokuba ethole imiyalelo kunesidingo.
Yiziphi izici ezahlukene imishini ezivamile zalolu hlobo?

- Flow izinga igesi engaxubani namakhemikhali ongafinyelela amalitha 60 ngomzuzu. Inani ubuncane ubhekwa egeleza amalitha amathathu ngomzuzu.
- Kokunye Welding isilinda ibekwe amalitha 100 we igesi engaxubani namakhemikhali noma esisheshayo.
zinhlobo ekhethwayo we Element
Semi-othomathikhi imishini Welding bahluke kakhulu endleleni abadalwe mshini zedivayisi wokondla wire electrode, ngakho okwamanje ukuba wenze idili likaMkhipheni. Ngo samuntu ezivamile, uhlobo pusher: yenza lula kakhulu umklamo sikaphalafini, kodwa kulokhu ubude hose lokondla igesi kukhawulwe kuze kube ngamamitha amathathu. ukusebenzisa kangcono design edonsa: hose kuleli cala lingafika amamitha 20.
Ngaphambi kokuthenga UWelder kufanele siqaphelisise kakhulu sikaphalafini. Njengoba umlomo wombhobho iyona element neze othwala hhayi kuphela ngokushesha, kufanele njengoba qualitatively ekhiqizwa. Sicela uqaphele ukuthi ngesikhathi Welding isidingo njalo ukuyihlanza Ukunamathela izingcezu slag. Kakhulu ngokucophelela ubuka ichopho isimo, njengoba kwaba njalo endabeni ka-ukulimala izinga Welding lwehla.
Okubalulekile! Ngaphambi ukupheka insimbi engagqwali semi-automatic, ukuthenga esikhundleni kits. On engagqwali wire futhi kushiya okuningi we igesi engaxubani namakhemikhali. Ukuze Welding yayo kudinga eqinile arc kagesi, insimbi asivumelani ngokuqinile umlomo wombhobho evuthayo othwala aphume ngokushesha.
Yini izinto kufanele lisetshenziswe umsebenzi?
Njengoba sekushiwo, bentambo ingasetshenziswa kusuka 0.5 kuya ku-3 mm obukhulu. Kunalokho kuba ohlabayo, ukushiswa kangcono arc, kujula Ukungena we indaba ashiselwe. Qaphela ukuthi kungenzeka ukusebenzisa electrode ukujiya 3 mm, kodwa "extra" milimitha ngamunye kufanele akhawunti ezengeziwe amperes 100.
Nasi amperage kanye voltage
Yiqiniso, amandla lamanje incike ukushuba we impahla ashiselwe, futhi ububanzi we wire esetshenziswa. I ukujiya inkulu, le sokungena-material ukujula umkhiqizo jikelele kancane. Okungenhla voltage, kujula kwema- kwensimbi. Nokho, kufanele sikhumbule ukuthi lokhu kwandisa inani impahla eshile slag, ububanzi bead kwandisa kakhulu. Voltage isethelwe force yamanje. Olunye ulwazi eyatholakala imiyalo umshini Welding.
Izinga okuphakelayo we electrode isethwe okusekelwe izici impahla kanye eyayidinga amandla weld. Isikhathi Welding incike ukushuba we impahla axhunyiwe, futhi okulindeleke umphetho ububanzi. Ngesivinini, ngakho sincoma ngokuqinile ukwenza ukuxhumana ewumngcingo kuphela ngoba uma uthola ezivuzayo ububanzi izinga ezinjengendle kuhambisana semali amanyela.
O igesi ukugeleza isilinganiso
I wire mkhulu, kulapho idliwe igesi engaxubani namakhemikhali ukuvikela yendwangu ukuba ashiselwe.
