Chisamaliro chiyenera kuchitidwa pamavutowa pakuwotcherera mapaipi osapanga dzimbiri

  Chitoliro chosapanga dzimbiri welded chitoliroamapangidwa ndi chitsulo kapena chitsulo mzere pambuyo crimping ndi makina ndi kufa.Chinsinsi cha chitsimikizo cha khalidwe la zitsulo zosapanga dzimbiri welded chitoliro ndi khalidwe la zipangizo.Choncho, zipangizo zonse mu fakitale pamaso ntchito, ayenera kufufuzidwa, kuphatikizapo: kudziwika maonekedwe, muyeso m'lifupi ndi makulidwe ofanana;Komanso, mankhwala zikuchokera ndi kumakoka mayeso cheke, oyenerera pamaso kupanga yachibadwa.Komabe, kupanga kwenikweni zitsulo zosapanga dzimbiri welded chitoliro nthawi zambiri amaoneka izi kapena vuto.Ndiye, kodi mukudziwa mavuto amene zitsulo zosapanga dzimbiri weld mapaipi sachedwa?Kodi zifukwa za mavutowa mu mipope zosapanga dzimbiri welded?Apa wolemba akupanga yankho ndi inu.

Mu ntchito kuwotcherera zitsulo zosapanga dzimbiri kuwotcherera chitoliro fakitale, mavuto amene sachedwa kuchitika ndi: osayenerera kuwotcherera msoko, kuwotcherera chosakwanira kapena kuwotchedwa, ming'alu ndi pores.Kunena zowona, ndi:

1. Kuwotcherera osayenerera ndi chifukwa cha kusankha kolakwika kwa magawo a ndondomeko yowotcherera kapena luso lopanda luso la ntchito.Kutsogolera kumtunda wautali ndi wochepa wa weld ndi wosiyana, ndiyeno kupanga mawonekedwe a weld si abwino kwambiri, kumbuyo kwa weld ndi concave, kuchititsa kuti kuwotcherera kufooke kwambiri, kotero kuti mphamvu yowotcherera iwonongeke. osakwanira.

2. Kuwotcherera kosakwanira kapena kuwotcherera kosakwanira kumatheka chifukwa cha zifukwa zotsatirazi: choyamba, yapano ndi yaying'ono;Chachiwiri, ukadaulo wa opareshoni sukhala waluso, liwiro lowotcherera liri mwachangu kwambiri, chilolezo cha matako ndi chaching'ono;Arc ndi yayitali kwambiri kapena arc sinagwirizane ndi weld.Ngati waya wowotcherera ndi chitsulo choyambira sichinaphatikizidwe pamodzi kapena chitsulo chowotcherera sichinaphatikizidwe m'deralo, gawolo liyenera kukonzedwa munthawi yake.Chifukwa chachikulu cha kuwotcherera ndi kutentha kwambiri.Kutentha kwa dziwe losungunuka ndikokwera kwambiri.Waya wowotcherera samawonjezedwa munthawi yake, chilolezo cha nthiti ndi chachikulu kwambiri;Liwiro la kuwotcherera ndilochedwa kwambiri.Izi zipangitsa kuphulika kumodzi kapena mosalekeza pa weld, kotero kuti mphamvu ya weld imafooka, kuti iwotchedwe.

3. Ming'alu ndi pores (1) Vuto lafupipafupi ndi ming'alu.Malinga ndi zochitika zosiyanasiyana za ming'alu, ming'alu yambiri imatha kugawidwa m'ming'alu yotentha ndi ming'alu yozizira.Hot ming'alu zimachitika chifukwa otentha ming'alu ndi makutidwe ndi okosijeni mtundu aumbike pamodzi intergranular malire pa kutentha kwa madzi zitsulo pa solidification kapena kutsika pang'ono kuposa olimba gawo mzere.Ngakhale ozizira mng'alu ndi ozizira mng'alu ndi transgranular katundu, chowala fracture ndipo palibe oxidizing mtundu kumachitika mu olimba gawo kusintha, kapena kukhalapo kwa diffused haidrojeni, ndi pansi zochita za kwambiri kuwotcherera shrinkage nkhawa pa kuzirala.Ngati ntchito kuwotcherera waya si kwa muyezo, kuwotcherera mkulu kutentha okhala nthawi yaitali kwambiri, chifukwa mu makutidwe ndi okosijeni, kutenthedwa ndi kupitirira kukula kwa galasi kukula, zinthu palokha ndi zosafunika kwambiri, kapena zinthu palokha n'zosavuta kuumitsa, koma komanso sachedwa kusweka.(2) Porosity kumachitika chifukwa pali madontho mafuta, okusayidi khungu ndi dzimbiri padziko kuwotcherera mbali ndi mawaya kuwotcherera, kapena kuwotcherera mu malo chinyezi, kapena argon mpweya ndi otsika chiyero, kapena argon gasi chitetezo ndi osauka, ndi wosungunula. dziwe ndi oxidized pa kutentha, kuwaza ndi zinthu zina n'zosavuta kubala porosity.Mavuto atatu omwe ali pamwambawa nthawi zambiri amapezeka pakuwotcherera kwa opanga machubu osapanga dzimbiri.
