Kwimveliso yewelding yokwenyani, amashishini amaninzi afumanisa ukuba xa oomatshini babo bokuwelda besenza amashiti afakwe igalvanized, amanqaku eweld ahlala kuphela kumaleko angaphezulu, esilela ukwenza iinuggets ezisebenzayo. Oku kubangela ukungonelanga kwamandla adibeneyo kwaye kuchaphazela kakhulu umgangatho wemveliso. Le nto ixhaphake ngokukodwa kumashishini okuvelisa iimoto kunye nezixhobo zekhaya.
Ngokusebenzisa-uhlalutyo olunzulu, kufunyaniswe ukuba unobangela ulele kwiimpawu ezizodwa zomaleko we-zinc{1}}okungaqhubi kakuhle kwe-thermal kunye nokuguquguquka okuphezulu{2}}okuthintela ubushushu ekugqithiseleni ngokufanelekileyo ngaphakathi kwishiti. Amandla olawulo achanekileyo ophakathi{4}}ngokuphindaphindiweyooomatshini bokuwelda amabalainikeza isisombululo sobugcisa esithembekileyo kulo mngeni.
-Uhlalutyo olunzulu lweNgxaki engunobangela
Ngokwemvelioomatshini bokuwelda amabalajongana nemiceli mngeni emininzi xa kusetyenzwa imathiriyeli eyenziwe ngegalvanized:
- Ukungahambi kakuhle kwe-thermal ye-zinc layer kudala umqobo we-thermal, ukuthintela ukuhanjiswa kobushushu kwizinto ezisisiseko.
- Ukushisa kwe-volatilization ye-zinc (malunga ne-907 degree) iphantsi kuneqondo lokushisa elinyibilikayo lensimbi, elibangela ukuqhuma kwangaphambili.
- Ukuguquguquka kwangoku kubangela ukusabalalisa ubushushu obungalinganiyo, kunye nokushisa okuphezulu kunye nokungabikho kwangaphakathi kokudibanisa.
- Umphunga we-zinc ungcolisa umphezulu we-electrode, uqhubekisela phambili ukuphazamisa ukusebenza kakuhle kokuhambisa ubushushu.
Izinto eziluncedo kwezobuGcisa{0}}zoomatshini bokuwelda bendawo rhoqo
Izandi zangoku-eziphakathioomatshini bokuwelda amabalajongana nemiba yewelding yomphezulu ngokusebenzisa le mpumelelo ilandelayo yetekhnoloji:
- Guqula umbane wamaza ombane ubephakathi-umqukumbelo we-DC amandla ku-800–2000 Hz.
- Ukufezekisa uzinzo oluphezulu kwimveliso yangoku, ukuphepha ukuguquguquka kwamandla okuqhelekileyo kwizixhobo zemveli.
- Imveliso ye-DC iphelisa isiphumo solusu, ivumela ubushushu ukuba bufikelele kwi-interface yokudibanisa iphepha ngokuthe ngqo.
- I-Millisecond-inqanaba lolawulo oluchanekileyo liqinisekisa amandla akhululwe ngexesha elifanelekileyo.
Izisombululo ezicwangcisiweyo
1. Ukuphucula i-Welding Parameters
- Xa usebenzisa{0}uomatshini bokuwelda bamaxesha aphakathi, ezi zicwangciso zilandelayo zeparameter ziyacetyiswa:
- Yandisa ngokufanelekileyo ixesha-loxinzelelo (ukwandisa nge-30-50%) ukuqinisekisa ukugxothwa ngokupheleleyo kwe-zinc layer.
- Yamkela "indlela esezantsi yangoku + umjikelo omde" welding mode.
- Cwangcisa iinkqubo zokufudumeza ezininzi-zenqanaba ukonyusa kancinci amandla welding.
- Sebenzisa-ulungiso oluphakathi{1}}loomatshini bokuwelda bamabala aphindaphindayo ukunyusa imida.
2. Ulawulo oluchanekileyo loxinzelelo lwe-Electrode
- Ukwandisa uxinzelelo lwe-electrode ngama-20-30% ukuququzelela ukugxothwa kwe-zinc layer.
- Gcina uxinzelelo oluzinzileyo kuyo yonke inkqubo ye-welding.
- Sebenzisa inkqubo ekrelekrele yokulawula uxinzelelo koomatshini bokuwelda bamabala aphakathi{0}.
- Qinisekisa intsimbi ethe ngqo-ku{1}}uqhagamshelwano lwentsimbi ukunciphisa ukumelana nobushushu.
3. UkuKhethwa kwe-Electrode kunye noYilo
- Khetha ii-electrodes ezineengcebiso ezisingqingqwa okanye ezingqukuva ukusasaza ubushushu obungaphezulu.
- Cebisa ioxide{0}}yokusasazwa{1}}eyomeleziweyo yemathiriyeli yobhedu yobhedu kubushushu obuphezulu{2}}kunye nokuchasana{3}}neempawu zokuncamathelisa.
- Idayamitha ye-Electrode kufuneka ibe ngamaxesha angama-5-6 ubukhulu beshiti ukwandisa ukuxinana kwangoku.
- Gqoka rhoqo i-electrodes ukugcina imeko yokusebenza kakuhle.
4. Inkqubo yoNyango lwaPhambili
- Ucoce ngokucokisekileyo amabala e-oyile angaphezulu kunye nee-oxides.
- Yenza ukugaya kakuhle kwendawo ye-welding xa kuyimfuneko.
- Gcina uburhabaxa obufanelekileyo bomphezulu ukukhuthaza ukuqhutywa kwangoku.
- Kuphephe ukucola okugqithisileyo okunokonakalisa i-anti{0}}i-corrosion coating.
Iziphumo zoPhumezo kunye noQinisekiso loMgangatho
Emva kokwamkela oomatshini bokuwelda bamabala aphakathi{0}}badityaniswe neenkqubo eziphuculweyo:
- Izinga lemfundo ye-welding yonyuka ukuya kuthi ga kwi-98%.
- Ubunzulu be-Nugget bufikelela kwi-70-80% yobukhulu beshiti.
- Amandla adibeneyo adibana nemigangatho ephezulu yomgangatho.
- Ubomi benkonzo ye-Electrode banda ngaphezu kwe-50%.
- Iindleko zemveliso zincitshiswe kakhulu.
