MIG kuwotcherera - mwamsanga ndi efficiently

Kuwotcherera - ndi chosasimbika ndondomeko kulola ambiri molondola ndi molondola kuchita okhazikika kugwirizana mbali kapena mbali nkhani zopangidwa ndi zitsulo zosiyana siyana. Chibwenzi, anakamba ndi zomwe zagwiridwa kupanga njira zosiyanasiyana ndipo njira kuwotcherera maphatikizidwe. Aliyense wa njira ali ubwino ndi kuipa.

Imodzi mwa njira wotchuka kuwotcherera ndi theka-zodziwikiratu kuwotcherera zosiyanasiyana atmospheres mpweya zozitetezera. Iwo sangathe kuchita ngakhale akatswiri oyenerera poyerekeza zofunika Buku Arc kuwotcherera. Pankhaniyi, ndondomeko amatenga nthawi yochepa. Chifukwa china chotulutsa nkhani luso mwambambande ndi sikutanthauza wotsatira anamuvula kuchokera slag lapansi. processing (phunziroli, utoto, etc.) welded katundu zikhoza kupangidwa mwamsanga kwambiri. Ntchito maphatikizidwe kuwotcherera theka-zodziwikiratu amalola kulumikiza wochepa thupi kwambiri zitsulo chidutswa (0.1 - 1.5 mm), kuchita polumikiza msoko pamodzi seams curvilinear m'mfundo kusamalira mmene yaing'ono. Ndi yabwino kuwotcherera ndondomeko ang'ono-ang'ono kapena kuŵeta.

dzina "zoopsa zoyenera" Njira imeneyi makamaka kwa waya. Ndipotu, izo ziri chimodzimodzi kuwotcherera wapadera waya elekitirodi yomwe ikuchitika mu mpweya inert Arc. Mfundo imene zochokera theka-zodziwikiratu kuwotcherera, ndi wosavuta. Wodyetsa kudya kuwotcherera waya amapangidwa kuti chipangizo kolandira, ndiyeno - mu zone china chotulutsa. wapadera zida ulamuliro chipangizo akutumikira kulamulira waya elekitirodi liwiro.

Kuyambira thupi ntchito monga makiyi imodzi thereto yobereka mpweya ndi waya. Isanafike chiyambi cha ndondomeko malo anafuna china chotulutsa msoko wodzala ndi kamwazi wa bunker wapadera. Malemeredwe ikuchitika Arc kutsetsereka patsogolo elekitirodi pamodzi welded m'mbali pamalo pamene elekitirodi phula ali nawo, kapena pamene kale chikugwirizana chakudya nadzaza kamwazi. Kawiri kawiri tidzakhala ndi kugogoda elekitirodi nsonga Unalimbitsa slag, ngati Arc chimatha ndi akayaka kamodzinso. Dongosololi nthawi zonse umachitikira ndi alternating panopa, ngakhale n'zothekanso ntchito mpaka kalekale.

MIG kuwotcherera - ndondomeko pang'ono makina. Kupita chofukizira pamodzi msoko owotcherera wopangidwa ndi manja, pa chinthu chilichonse ndi motsindika crutch wapadera kuti aikidwa pa mankhwala. Ntchito ngati feeders m'manja ndipo n'kupuma, kusankha zimadalira ntchito yeniyeni kuwotcherera. maelekitirodi The amasankhidwa molingana ndi katundu wa zitsulo welded ndi makhalidwe china chotulutsa kupeza. The mpweya kutetezedwa, mmene kuwotcherera imachitidwa theka komanso anasankha zochokera katundu wa welded zitsulo. Chifukwa mpweya zitsulo otsika kutetezedwa mpweya amalenga mpweya woipa (NKHA _2), argon angathe kugwiritsidwa ntchito. Gasi umaperekedwa kwa nozzle ndi, chimakankhira mpweya m'deralo kuwotcherera ndi kuteteza msoko.

Kugula zipangizo kuwotcherera, ogula ambiri amafuna kupereka komanso kuwotcherera zotayidwa. Chifukwa chikhalidwe cha zitsulo, theka-zodziwikiratu kuwotcherera wa zotayidwa ndi sayansi zovuta kuposa pawiri katundu zitsulo. Mavuto kugwirizana ndi kusiyana yofunika kwambiri limatsogolera kutentha kwa zotayidwa (660 ° C) ndi filimu zoteteza pamwamba pake (2200 ° C). Pezani khalidwe china chotulutsa malowedwe ndi wabwino theka-zodziwikiratu m'malo argon n'zotheka, koma apa zonse kudalira pa luso, kuti akhale mmisiri luso la owotcherera kuchita ntchito.
