1.Momwe mungachitireweld wofatsa zitsulo?
Chitsulo chochepa cha carbon chili ndi mpweya wochepa komanso pulasitiki yabwino, ndipo imatha kukonzedwa mumitundu yosiyanasiyana yamagulu ndi zigawo.Pakuwotcherera, sikophweka kupanga mawonekedwe olimba, ndipo chizolowezi chotulutsa ming'alu chimakhalanso chaching'ono.Panthawi imodzimodziyo, si zophweka kupanga pores.Ndiwowotcherera bwino kwambiri.
Kuwotcherera chitsulo chochepa cha carbon ndi kuwotcherera kwa gasi, kuwotcherera kwa arc, kuwotcherera kwa arc kumadzi, kuwotcherera kotetezedwa ndi mpweya ndi njira zina zitha kupeza zolumikizira zabwino.Osatenthetsa kwa nthawi yayitali mukamagwiritsa ntchito kuwotcherera gasi, apo ayi mbewu zomwe zili m'dera lokhudzidwa ndi kutentha zimakula mosavuta.Pamene olowa ndi olimba kwambiri ndi kutentha yozungulira ndi otsika, workpiece ayenera preheated kuti 100 ~ 150 ° C kupewa ming'alu.
2.Kodi kuwotcherera sing'anga carbon zitsulo?
Chifukwa cha kuchuluka kwa mpweya wa carbon carbon steel wapakati, msoko wowotcherera ndi malo omwe amakhudzidwa ndi kutentha amatha kukhala ndi zida zolimba ndipo zimayambitsa ming'alu, choncho ziyenera kutenthedwa mpaka pafupifupi 300 ° C musanawotchere, ndipo kuziziritsa pang'onopang'ono kumafunika pambuyo pa kuwotcherera.Itha kuwotcherera ndi kuwotcherera gasi, kuwotcherera pamanja arc ndi kuwotcherera kwa gasi.Zipangizo zowotcherera ziyenera kugwiritsa ntchito AWS E7016, AWS E7015 ndi ma elekitirodi ena okhala ndi kukana bwino kwa ming'alu.
3.Momwe mungawotchere aluminiyamu ndi aluminium alloy?
Aluminiyamu ndi zitsulo zotayidwa ndizosavuta kupanga mafilimu a oxide okhala ndi mawonekedwe akuluakulu komanso malo osungunuka kwambiri panthawi yowotcherera.Filimu ya oxide iyi imathanso kuyamwa madzi ambiri, kotero zolakwika monga ma slag inclusions, kusakanizika koyipa, ndi pores zimatha kuchitika pakuwotcherera.Kuphatikiza apo, ma aluminiyamu aloyi Komanso amakonda ming'alu matenthedwe.Kuwotcherera aluminium ndi ma aluminiyamu aloyi amatha kupangidwa ndi kuwotcherera mpweya kapena kuwotcherera kwa arc pamanja.Komabe, kutentha kwa kuwotcherera kwa gasi sikunayike, ndipo kutentha kwa aluminiyamu kumathamanga, kotero kuti kupanga bwino kumakhala kochepa, ndipo kusinthika kwa workpiece ndi kwakukulu, kotero sikugwiritsidwa ntchito kawirikawiri kupatula mbale zoonda.Pakalipano, njira zambiri zowotcherera za AC argon arc zimagwiritsidwa ntchito powotcherera zotayidwa ndi aluminiyamu, chifukwa zimakhala ndi kutentha kwakukulu, kutsekemera kokongola, mapindikidwe ang'onoang'ono, chitetezo cha argon, ndipo chingalepheretse slag inclusions ndi pores.Ngati kuwotcherera kwa arc kwamanja kumagwiritsidwa ntchito powotcherera aluminiyamu, ndikoyenera mbale zokhuthala pamwamba pa 4mm.
Mitundu ya ndodo zowotcherera zomwe zimagwiritsidwa ntchito ndi aluminiyamu 109, aluminium 209 ndi aluminiyamu 309. Zonsezi ndi ma electrode opangidwa ndi mchere okhala ndi kukhazikika kwa arc, zomwe zimafuna DC reverse magetsi.
4.Momwe mungawotcherera titaniyamu ndi titaniyamu?
Titaniyamu ndi chinthu chogwira ntchito kwambiri.M'madzi ndi olimba pamwamba pa 600 ° C, ndizosavuta kuchitapo kanthu ndi mpweya, nayitrogeni, haidrojeni ndi mpweya wina kuti apange zonyansa zowononga ndi embrittle titaniyamu.Choncho, kuwotcherera mpweya-acetylene, kuwotcherera pamanja arc kapena kuwotcherera mpweya wina wotetezedwa sikungagwiritsidwe ntchito pa titaniyamu ndi titaniyamu aloyi, koma kuwotcherera kwa argon arc, kuwotcherera ma elekitironi mtengo ndi kuwotcherera kungagwiritsidwe ntchito.
mbale woonda m'munsimu 3mm ndi welded ndi kuwotcherera argon arc, magetsi chikugwirizana mwachindunji panopa, chiyero cha mpweya wa argon si zosakwana 99.98%, nozzle ayenera kukhala pafupi kwambiri ndi workpiece, ndi kuwotcherera panopa ayenera kukhala yaying'ono, ndipo liwiro la kuwotcherera liyenera kukhala lachangu.Sinthani mawonekedwe a kristalo ndikuchotsani kupsinjika kwa kuwotcherera.
5.Momwe mungachitireweld mkuwandi aloyi zamkuwa?
Kuwotcherera kwa aloyi zamkuwa ndi zamkuwa kumakhala ndi zovuta zambiri, chifukwa matenthedwe awo amawotchera ndi abwino kwambiri, choncho n'zosavuta kuyambitsa zolakwika monga kusakwanira komanso kusakanizika bwino.Pambuyo kuwotcherera, workpiece adzakhala ndi mapindikidwe lalikulu, ndi weld ndi fusion zone amakhalanso sachedwa ming'alu ndi ambiri pores.Zomwe zimapangidwira zophatikizira, makamaka pulasitiki ndi kulimba ndizotsika kuposa zazitsulo zoyambira.Kuwotcherera gasi kungagwiritsidwe ntchito kuwotcherera mkuwa wofiira, koma mphamvu zake ndizochepa kwambiri, mapindikidwe ake ndi aakulu, ndipo amafunika kutenthedwa mpaka pamwamba pa 400 ° C, ndipo ntchito sizili bwino.Kuwotcherera kwa arc pamanja kutha kugwiritsa ntchito maelekitirodi amkuwa 107 kapena mkuwa 227, magetsi amasinthidwa ndi DC, arc imasungidwa motsika momwe mungathere, ndipo njira yolumikizirana yofananira imagwiritsidwa ntchito kukonza mawonekedwe ake.Kuwotcherera nyundo pambuyo kuwotcherera kuti kuwongolera bwino kwa weld.Ngati kuwotcherera kwa argon tungsten arc kumagwiritsidwa ntchito, zolumikizira zowotcherera zapamwamba zitha kupezeka ndipo ma weldments amatha kuchepetsedwa.Waya 201 amagwiritsidwa ntchito powotcherera waya.Ngati waya wofiyira wamkuwa T2 agwiritsidwa ntchito, flux 301 iyeneranso kugwiritsidwa ntchito.Mphamvu yamagetsi imatengera kulumikizana kwabwino kwa DC.Wogwiritsa ntchito ndi waya wowotcherera ayenera kutsukidwa mosamala pakuwotcherera kuti achepetse pores ndi ma slag inclusions.Kuthamanga kwamakono komanso kuthamanga kwambiri kuyenera kugwiritsidwa ntchito powotcherera.
Kuwotcherera mpweya nthawi zambiri ntchito kuwotcherera mkuwa, ndi kuwotcherera waya akhoza kukhala waya 221, waya 222 kapena waya 224, etc. Mawaya awa ali pakachitsulo, malata, chitsulo ndi zinthu zina, amene angathe kuchepetsa moto imfa ya nthaka mu dziwe losungunuka. .Chifukwa cha kutentha kwa mpweya wochepa, kutentha kwa nthaka mu mkuwa kumatha kuchepetsedwa;pang'ono makutidwe ndi okosijeni lawi ntchito kuphimba pamwamba pa dziwe losungunuka ndi wosanjikiza wa zinki okusayidi filimu, amene angathe kuchepetsa evaporation nthaka.Kuphatikiza apo, mkuwa ukhoza kuwotcherera ndi kuwotcherera kwa arc ndi argon tungsten arc kuwotcherera.
6.Kodi kuwotcherera chitsulo chochepa cha aloyi ndi chiyani?
Chitsulo chochepa cha alloy ndi chitsulo chomwe chimagwiritsidwa ntchito kwambiri popangana.Chinthu chachikulu cha mtundu uwu wa kuwotcherera zitsulo ndikuti malo omwe amakhudzidwa ndi kutentha kwa olowa amakhala ndi chizoloŵezi cholimba kwambiri, ndipo ma hydrogen amatha kuyambitsa ming'alu yozizira mu mgwirizano.Chizoloŵezi chofuna kuumitsa ndi kuzizira kumawonjezeka pamene mphamvu yachitsulo chochepa cha alloy chikukwera.
7.Kodi njira yowotcherera ya chitsulo 16 ya manganese ndi iti?
16 Manganese zitsulo kuwotcherera ayenera kugwiritsa ntchito mphambano 506 kapena mphambano 507 ndi maelekitirodi zina zofunika, DC n'zosiyana kugwirizana.Pamene chizolowezi mng'alu structural si lalikulu, asidi kuwotcherera ndodo monga mphambano 502 kapena mphambano 503 angagwiritsidwenso ntchito, ndipo ndondomeko kuwotcherera ndi ofanana ndi chitsulo chochepa mpweya;pamene kuwotcherera kumakhala kolimba komanso kutentha kozungulira kumakhala kochepa kuposa -10 ° C, kutenthetsa musanawotchere kumafunika.Zotsatira zokhutiritsa zitha kupezedwa ndi kuwotcherera kwa arc pamanja, kuwotcherera arc pansi pamadzi kapena kuwotcherera kwa electroslag.
8.Kodi njira yowotcherera ya No. 15 manganese vanadium ndi No. 15 manganese titanium chitsulo ndi chiyani?
Onse 15 manganese vanadium ndi 15 manganese titaniyamu ndi 40 kg wamba low alloy chitsulo.Chifukwa cha kuwonjezera kwa vanadium kapena titaniyamu, mphamvu yachitsulo imakhala yabwino;koma kuwotcherera kwawo, zida zowotcherera ndi njira zowotcherera ndizofanana ndi zitsulo 16 za manganese.Kufananiza ndi kofanana.Pamene kumizidwa arc automatic kuwotcherera ntchito, kuwotcherera waya akhoza kukhala 08 manganese mkulu, 08 manganese 2 silikoni, ndi flux 431, flux 350 kapena flux 250 akhoza kupeza zotsatira zogwira mtima.
9.Kodi njira yowotcherera yachitsulo cha 18 manganese molybdenum niobium ndi iti?
No. 18 manganese-molybdenum-niobium zitsulo ndi 50 makilogalamu mkulu-mphamvu wamba otsika aloyi zitsulo, amene nthawi zambiri ntchito popanga zinthu zofunika kuwotcherera monga ziwiya mkulu-anzanu ndi ng'oma kukatentha.Chifukwa cha mphamvu zake zazikulu komanso kuuma kwake kwakukulu, njira zowotcherera m'deralo ziyenera kuchitidwa panthawi yowotcherera.Samalani kuumitsa ma elekitirodi ndikuyeretsa poyambira kuti mupewe ming'alu yozizira yoyambitsidwa ndi haidrojeni.Kuwotcherera arc pamanja kumagwiritsa ntchito mphambano 607 ndi maelekitirodi ena;Kuwotcherera kwa arc kumagwiritsa ntchito waya wowotcherera wokhala ndi manganese apamwamba 08 ndi molybdenum, ndipo amatha kuwotcherera ndi flux 250 kapena flux 350.
