Kodi Oxy-Acetylene Hardfacing Method ndi chiyani

Kuyambitsa kuwotcherera kwa Oxy-Acetylene

Pali njira zambiri zowotcherera pophatikiza zitsulo. Kuchokera kuwotcherera kwa flux-cored kupita ku GTAW/TIG kuwotcherera, mpaka kuwotcherera kwa SMAW, kuwotcherera kwa GMAW/MIG, njira iliyonse yowotcherera imagwira ntchito inayake malinga ndi momwe zinthu zilili komanso mitundu ya zinthu zomwe zimawotcherera.

Mtundu wina wa kuwotcherera ndi oxy-acetylene kuwotcherera. Kuwotcherera kwa oxy-fuel, oxy-acetylene welding ndi njira yomwe imadalira kuyaka kwa okosijeni ndi gasi wamafuta, makamaka acetylene. Mwina ambiri a inu mumamva kuwotcherera kwamtunduwu kumatchedwa "kuwotcherera gasi."

Nthawi zambiri, kuwotcherera gasi kumagwiritsidwa ntchito powotcherera zigawo zachitsulo zopyapyala. Anthu amathanso kugwiritsa ntchito kuwotcherera kwa oxy-acetylene powotchera, monga kutulutsa mabawuti owumitsidwa ndi mtedza ndikuwotchera katundu wolemera popinda ndi ntchito zofewa.

Kodi kuwotcherera kwa Oxy-Acetylene Kumagwira Ntchito Motani?

Kuwotcherera kwa Oxy-acetylene kumagwiritsa ntchito lawi lamoto lotentha kwambiri, lomwe limapangidwa powotcha gasi (kawirikawiri acetylene) wosakanikirana ndi mpweya wabwino. Zoyambira zimasungunuka ndi ndodo yodzazitsa pogwiritsa ntchito lawi lamoto lophatikizana ndi mpweya wa oxy-mafuta kupyola nsonga ya nyali yowotcherera.

Gasi wamafuta ndi mpweya wa okosijeni amasungidwa mu masilinda achitsulo oponderezedwa. Owongolera mu silinda amachepetsa kuthamanga kwa gasi.

Mpweya umayenda kudzera mu mapaipi osinthika, chowotcherera chimayang'anira kutuluka kudzera mu nyali. Ndodo yodzaza imasungunuka ndi zinthu zoyambira. Komabe, kusungunula zidutswa ziwiri zazitsulo kumathekanso popanda kufunikira kwa ndodo yodzaza.

Kodi Kusiyanitsa Kwakukulu Pakati pa Oxy-Acetylene Welding ndi Mitundu Ina Yowotcherera Ndi Chiyani?

Kusiyana kwakukulu pakati pa kuwotcherera kwa oxy-fuel ndi arc kuwotcherera monga SMAW, FCAW, GMAW, ndi GTAW ndiye gwero la kutentha. Kuwotchera kwamafuta a Oxy kumagwiritsa ntchito lawi monga gwero la kutentha, lomwe limafika kutentha mpaka madigiri 6,000 Fahrenheit.

Kuwotcherera kwa Arc kumagwiritsa ntchito magetsi monga gwero la kutentha, kufika kutentha kwa pafupifupi 10,000 F. Mulimonsemo, mudzafuna kukhala osamala komanso otetezeka pamene mukuwotchera mozungulira kutentha kwamtundu uliwonse.

M'masiku oyambirira kuwotcherera, kuwotcherera kwa oxyfuel kunkagwiritsidwa ntchito powotcherera mbale zochindikala. Masiku ano, imagwiritsidwa ntchito kwambiri pazitsamba zopyapyala. Njira zina zowotcherera arc, monga GTAW, zikusintha njira yowotcherera ya oxy-fuel pazitsulo zopyapyala.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
