Kusiyanitsa Pakati pa Kuwotcherera Kuwotcherera ndi Kuyang'ana Kwambiri

Kuwotcherera pamwamba ndi kuyang'ana molimba ndi njira ziwiri zomwe zimagwiritsidwa ntchito nthawi zambiri m'makampani kuti zithandizire kulimba komanso kukana kuvala kwa zinthu zomwe zimagwira ntchito movutikira. Ngakhale kuti njira zonsezi zimafuna kupititsa patsogolo mawonekedwe a chinthu, pali kusiyana kosiyana pakugwiritsa ntchito, zipangizo zomwe zimagwiritsidwa ntchito, ndi zotsatira zake. M'nkhaniyi, tiwona kusiyana pakati pa kuwotcherera pamwamba ndi kuyang'ana molimba malinga ndi ndondomeko, zipangizo, ndi ubwino ndi malire awo.

Kodi Overlay Welding ndi chiyani

Kuwotcherera pamwamba, komwe kumadziwikanso kuti cladding kapena pamwamba, kumaphatikizapo kuyika zinthu zomwe zimagwirizana pamwamba pa chitsulo choyambira. Izi zimatheka kudzera munjira monga kuwotcherera kwa arc (SAW), kuwotcherera kwachitsulo cha gasi (GMAW), kapena kuwotcherera kwa plasma arc (PTAW). Zinthu zokutira zimasankhidwa potengera kugwirizana kwake ndi chitsulo choyambira ndi zomwe zimafunidwa pamwamba.

Zida Zogwiritsidwa Ntchito Pakuwotcherera Kuphimba:

1. Weld Overlay: Mu njira iyi, zinthu zokutira nthawi zambiri zimakhala zitsulo zodzaza ndi weld, zomwe zimatha kukhala chitsulo chochepa cha carbon, chitsulo chosapanga dzimbiri, kapena alloy-based alloy. Zida zokutira weld zimasankhidwa kutengera kukana kwake kwa dzimbiri, kukana kuvala, kapena kutentha kwambiri.

Ubwino wa Overlay Welding:

1. Kusinthasintha: Kuwotcherera pamwamba kumalola kuti zipangizo zambiri zigwiritsidwe ntchito pakusintha kwapamwamba, zomwe zimapereka kusinthasintha pokonza zinthu zowonongeka malinga ndi zofunikira zenizeni.

2. Zotsika mtengo: Kuwotcherera pamwamba kumapereka njira yotsika mtengo yosinthira mawonekedwe a pamwamba pazigawo, monga gawo lochepa chabe la zinthu zamtengo wapatali zomwe zimagwiritsidwa ntchito pazitsulo zoyambira.

3. Kutha Kukonzekera: Kuwotcherera pamwamba kungagwiritsidwenso ntchito kukonzanso malo owonongeka kapena otha, kukulitsa moyo wautumiki wa zigawo zikuluzikulu.

Zochepa Zowotcherera Zowonjezera:

1. Mphamvu ya Bond: Mphamvu ya mgwirizano pakati pa zinthu zowonongeka ndi zitsulo zoyambira zingakhale zodetsa nkhawa, chifukwa kugwirizana kosakwanira kungayambitse delamination kapena kulephera msanga.

2. Kunenepa Kwapang'ono: Kuwotcherera zokutira kumangokhala mamilimita angapo a makulidwe, kupangitsa kuti ikhale yocheperako pamapulogalamu omwe amafunikira magawo okhuthala a zinthu zowonjezedwa.

3. Malo Okhudzidwa ndi Kutentha (HAZ): Kuyika kwa kutentha panthawi yowotcherera kungapangitse kuti pakhale malo okhudzidwa ndi kutentha, omwe angasonyeze zinthu zosiyanasiyana kusiyana ndi zokutira ndi zipangizo zapansi.

Kodi Kulimbana Ndi Vuto Ndi Chiyani

Kuyang'ana molimba, komwe kumadziwikanso kuti kuwotcherera kolimba kapena kumanga-ups, kumaphatikizapo kuyika chinsalu chosamva kuvala pamwamba pa chinthu kuti chikhale cholimba kuti chisawonongeke, kukokoloka, ndi kukhudzidwa. Njira imeneyi imagwiritsidwa ntchito makamaka ngati vuto lalikulu ndi kukana kuvala.

Zida Zogwiritsidwa Ntchito Pamaso Olimba:

1. Ma Aloyi Owona Olimba: Zida zolimba ndi zosakaniza zomwe zimakhala ndi chitsulo choyambira (monga chitsulo) ndi zinthu zophatikizira monga chromium, molybdenum, tungsten, kapena vanadium. Ma alloys awa amasankhidwa chifukwa cha kuuma kwawo kwapadera komanso kukana kuvala.

Ubwino Woyang'ana Kwambiri:

1. Kuuma Kwambiri: Zida zolimba zimasankhidwa chifukwa cha kuuma kwawo kwapadera, zomwe zimalola kuti zigawozo zikhale zolimba kuvala, kukhudzidwa, ndi kupanikizika kwambiri.

2. Kukaniza Kuvala: Kuyang'ana molimba kumawongolera kwambiri kukana kwapamwamba, kukulitsa moyo wautumiki wa zigawo mumikhalidwe yovuta kwambiri.

3. Zosankha za Makulidwe: Kuyang'ana kolimba kumatha kuyikidwa mumagulu a makulidwe osiyanasiyana, kulola kuwongolera bwino kuchuluka kwa zinthu zosavala zomwe zawonjezeredwa.

Zochepa Zokumana Ndi Zovuta:

1. Kusinthasintha Kwapang'onopang'ono: Zida zolimba zimangoyang'ana kwambiri kuti zisamavale ndipo sizingakhale ndi zosafunikira kuti zisawonongeke, kutentha kwambiri, kapena zina zomwe zimafunikira pakugwiritsa ntchito zina.

2. Mtengo: Ma alloys olimba amakhala okwera mtengo kwambiri poyerekeza ndi zida zowotcherera zokutira, zomwe zitha kukulitsa mtengo wakusintha kwapamtunda.

3. Kukonzekera Kovuta: Kamodzi kagawo kolimba kamene kamagwiritsidwa ntchito, kungakhale kovuta kukonzanso kapena kusintha pamwamba, chifukwa kuuma kwakukulu kwa zinthu kumapangitsa kuti zitsulo zikhale zochepa.

Pomaliza:

Kuwotcherera pamwamba ndi kuyang'ana molimba ndi njira zosiyana zosinthira pamwamba zomwe zimagwiritsidwa ntchito kukulitsa kukana komanso kulimba kwa zida. Kuwotcherera pamwamba kumapereka mphamvu zambiri komanso zotsika mtengo, zomwe zimalola kuti pakhale zosankha zingapo muzinthu zokutira. Ndizoyenera kugwiritsa ntchito zomwe zimafuna kukana kwa dzimbiri, kukana kuvala, kapena kuwongolera kutentha kwambiri. Mosiyana ndi izi, nkhope zolimba zimayang'ana makamaka pa kukana kuvala, kugwiritsa ntchito ma alloys okhala ndi kuuma kwapadera. Ndi yabwino kwa mapulogalamu omwe akhudzidwa kwambiri ndi abrasion, kukokoloka, ndi kukhudzidwa. Kumvetsetsa zofunikira zenizeni zomwe zimagwiritsidwa ntchito ndi zomwe zimafunidwa pamwamba ndizofunika kwambiri posankha njira yoyenera kuti mukwaniritse zotsatira zomwe mukufuna.
