Zikafika pazigawo zazitsulo zamapepala ndi zotsekera, kuwotcherera kumatha kuthana ndi zovuta zambiri zamapangidwe.Ichi ndichifukwa chake timapereka njira zosiyanasiyana zowotcherera monga gawo lazopanga zathu, kuphatikizakuwotcherera malo,kuwotcherera msoko, zowotcherera fillet, zowotcherera mapulagi, ndi zowotcherera.Koma popanda kugwiritsa ntchito njira zoyenera zowotcherera, njira yowotcherera zitsulo zoyezera-gauge imatha kukhala yovuta komanso yosafuna kukanidwa.Tsamba ili labulogu lifotokoza chifukwa chake timagwiritsa ntchitoCold Metal Transfer (CMT) kuwotchererapa kuwotcherera wamba kwa MIG (gasi wa inert wachitsulo) kapena kuwotcherera kwa TIG (gesi woyika tungsten).

th njira zina kuwotcherera

Pakuwotcherera, kutentha kuchokera ku nyali yowotcherera kumatenthetsa chogwirira ntchito ndi waya wa chakudya mu nyaliyo, kuzisungunula ndikuziphatikiza pamodzi.Kutentha kukakwera kwambiri, chodzazacho chimasungunuka chisanafike chogwirira ntchito ndikupangitsa kuti madontho achitsulo aphwanyike pagawolo.Nthawi zina, kuwotcherera kumatha kutenthetsa ntchitoyo mwachangu ndikuyambitsa kusokoneza kapena zikavuta kwambiri, mabowo amatha kuwotchedwa gawo lanu.

Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi kuwotcherera kwa MIG ndi TIG.Zonsezi zimakhala ndi kutentha kwapamwamba kwambiri poyerekeza ndiCold Metal Transfer (CMT) kuwotcherera.

Zomwe takumana nazo, kuwotcherera kwa TIG ndi MIG sikwabwino kujowina zitsulo zokhala ndi kuwala.Chifukwa cha kutentha kwadzaoneni, pali kuwombana ndi kusungunuka, makamaka pazitsulo zosapanga dzimbiri ndi aluminiyamu.Asanakhazikitsidwe kuwotcherera kwa CMT, kuwotcherera kwachitsulo chopepuka chopepuka kumakonda kukhala kwaluso kuposa njira yopangira mwaukadaulo.

Kodi CMT Imagwira Ntchito Motani?

CMT kuwotcherera kuli ndi arc yokhazikika mwapadera.The pulsed arc imapangidwa ndi gawo loyambira lomwe lili ndi mphamvu yochepa komanso gawo laposachedwa lomwe lili ndi mphamvu yayikulu popanda mabwalo amfupi.Izi zimapangitsa kuti pafupifupi sipatter ipangidwe.(Spatter ndi madontho azinthu zosungunula zomwe zimapangidwa pafupi kapena pafupi ndi arc yowotcherera.).

Pakugunda komweku, madontho akuwotcherera amachotsedwa m'njira yolunjika pogwiritsa ntchito kugunda kwanthawi yake.Chifukwa cha njirayi, arc imangoyambitsa kutentha kwa nthawi yochepa kwambiri panthawi yoyaka moto.

Kutalika kwa arc kumadziwika ndikusinthidwa mwamakina.Arc imakhala yokhazikika, ziribe kanthu kuti pamwamba pa workpiece ndi yotani kapena momwe wogwiritsira ntchito amawotchera mofulumira.Izi zikutanthauza kuti CMT itha kugwiritsidwa ntchito kulikonse komanso pamalo aliwonse.

Njira ya CMT imafanana ndi kuwotcherera kwa MIG.Komabe, kusiyana kwakukulu kuli mu chakudya cha waya.M'malo mopitilira kupita patsogolo mu dziwe la weld, ndi CMT, waya amachotsedwa nthawi yomweyo.Waya wowotcherera ndi mpweya wotchinga amadyetsedwa kudzera mu nyali yowotcherera, ma arcs amagetsi pakati pa waya wowotcherera ndi pamwamba - izi zimapangitsa kuti nsonga ya waya wa weld isungunuke ndikugwiritsidwa ntchito pamwamba pa kuwotcherera.CMT imagwiritsa ntchito kuyatsa ndi kutseka kwa chotenthetsera kuti chitenthetse bwino ndi kuziziritsa waya wowotcherera kwinaku akubweretsa waya kulowa ndi kusakhudzana ndi dziwe la weld nthawi zambiri pamphindikati.Chifukwa imagwiritsa ntchito kugunda m'malo mopitilira mphamvu,Kuwotcherera kwa CMT kumapanga gawo limodzi mwa magawo khumi a kutentha komwe MIG imachita.Kuchepetsa kutentha kumeneku ndiye phindu lalikulu la CMT ndichifukwa chake amatchedwa "Cold" kusamutsa zitsulo.

Zosangalatsa zofulumira: Wopanga kuwotcherera kwa CMT amafotokoza kuti, "kutentha, kuzizira, kutentha, kuzizira, kuzizira."

Muli ndi Zopanga M'malingaliro?Lankhulani ndi Ife

Ngati muli ndi mafunso okhudza kuphatikiza kuwotcherera mu kapangidwe kanu,kufikirakuti ndiyambe.Protocase imatha kupanga zotchingira zanu ndi magawo anu, mpaka masiku 2-3, popanda kuyitanitsa zochepa.Tumizani ma prototypes anu apamwamba kamodzi kapena mapangidwe otsika ndikuyambitsa mapulojekiti anu lero.
