Njira zosiyanitsira mapaipi azitsulo zowotcherera ndi mapaipi opanda zitsulo.

1. Metallography

Metallography ndi imodzi mwa njira zazikulu kusiyanitsa mipope zitsulo welded kuchokeramipope yachitsulo yopanda msoko. Mkulu pafupipafupi kukana welded zitsulo mipope sawonjezera kuwotcherera zipangizo, kotero kuwotcherera msoko mu welded zitsulo chitoliro ndi yopapatiza kwambiri. Ngati njira yopukutira movutikira kenako ndikuwononga imagwiritsidwa ntchito, msoko wa weld suwoneka bwino. Kamodzi mkulu-pafupipafupi kukana welded zitsulo chitoliro ndi welded ndipo sanalandire chithandizo kutentha, dongosolo kuwotcherera adzakhala kwenikweni osiyana ndi makolo chuma chitoliro. Panthawi imeneyi, njira metallographic angagwiritsidwe ntchito kusiyanitsa mipope zitsulo welded ku mipope zitsulo opanda msoko. Posiyanitsa mipope iwiri yachitsulo, m'pofunika kudula chitsanzo chaching'ono ndi kutalika ndi 40mm m'lifupi pa malo owotcherera, kuchita mphesa zowonongeka, kupukuta bwino ndi kupukuta, kenako kuyang'ana kapangidwe kake pansi pa microscope ya metallographic. Pamene ferrite ndi widmanstatten, zinthu za makolo ndi mawonekedwe a weld zone awonedwa, chitoliro chachitsulo chowotcherera ndi chitoliro chachitsulo chopanda msoko amatha kusiyanitsa molondola.

2. Njira ya dzimbiri

Pogwiritsira ntchito njira ya dzimbiri kusiyanitsa mipope yachitsulo yowotcherera ndi mipope yachitsulo yopanda msoko, chowotcherera cha chitoliro chachitsulo chosungunuka chiyenera kupukutidwa. Pambuyo kupukuta kumalizidwa, zizindikiro zopukutira ziyenera kuwoneka. Kenako, nkhope yomaliza imapukutidwa ndi sandpaper pa weld, ndipo nkhope yomaliza imathandizidwa ndi 5% nitric acid alcohol solution. Ngati chowotcherera chodziwikiratu chikuwonekera, zitha kutsimikiziridwa kuti chitoliro chachitsulo ndi chitoliro chachitsulo chowotcherera. Palibe kusiyana koonekeratu kumapeto kwa nkhope ya chitoliro chosasunthika chachitsulo pambuyo pa dzimbiri.

3. Kusiyanitsa mipope zitsulo welded ndi zitsulo zitsulo mipope malinga ndi ndondomeko

M'kati mwa kusiyanitsawelded zitsulo mapaipindi mipope zitsulo zopanda msoko malinga ndi ndondomeko, mipope onse welded zitsulo ndi welded malinga ndi njira monga ozizira anagubuduza ndi extrusion. Komanso, pamene mkulu pafupipafupi, otsika pafupipafupi arc kuwotcherera mapaipi ndi kukana kuwotcherera mapaipi ntchito kuwotcherera mipope zitsulo, wozungulira chitoliro kuwotcherera ndi kuwotcherera molunjika chitoliro adzapangidwa, amene adzapanga mipope kuzungulira zitsulo, lalikulu zitsulo mapaipi, chowulungika zitsulo. mapaipi, mapaipi azitsulo a katatu, mapaipi achitsulo a hexagonal, mapaipi achitsulo ophwanyika, mapaipi azitsulo octagonal, ndi mapaipi achitsulo ovuta kwambiri. Mwachidule, njira zosiyanasiyana zidzapanga mipope yachitsulo yamitundu yosiyanasiyana, kotero kuti mipope yachitsulo yonyezimira ndi mipope yachitsulo yopanda msoko imatha kusiyanitsa bwino. Komabe, posiyanitsa mipope yachitsulo yopanda msoko molingana ndi ndondomekoyi, amasiyanitsidwa makamaka ndi njira zochiritsira zotentha komanso zozizira, komanso mapaipi opanda zitsulo ali ndi mitundu iwiri ikuluikulu, yomwe ndi mipope yachitsulo yotentha yotentha komanso yozizira- adagulung'undisa zitsulo mapaipi. Mipope yachitsulo yosakanizidwa ndi yotentha imapangidwa ndi kuphulika, kugudubuza ndi njira zina, makamaka mipope yachitsulo yokhala ndi m'mimba mwake ndi wandiweyani imawotchedwa ndi ndondomekoyi; mapaipi ozizira amapangidwa ndi kujambula kozizira kwa mapaipi, ndipo mphamvu ya zinthuzo imakhala yochepa, koma mawonekedwe ake akunja ndi amkati ndi osalala.
