Metallurgical katundu wa zinthu
Mapaipi opindika aarc otalikirapo amapangidwa kuchokera ku mbale zachitsulo, pomwe mapaipi ozungulira amapangidwa kuchokera kumakoyilo otenthedwa.The otentha adagulung'undisa Mzere wagawo kugubuduza ndondomeko ali angapo ubwino ndipo ali ndi njira metallurgical mphamvu kupeza kupanga mkulu khalidwe chitoliro mzere zitsulo.Mwachitsanzo, maimidwe linanena bungwe ali okonzeka ndi madzi kuzirala dongosolo imathandizira kuzirala, amene amalola kugwiritsa ntchito nyimbo otsika aloyi tikwaniritse magiredi apadera mphamvu ndi otsika kutentha toughness, potero kuwongolera weldability wa chitsulo.Komabe, dongosololi silikupezeka m'mafakitale opanga mapepala achitsulo.Zomwe zili ndi aloyi (zofanana ndi mpweya) zamakoyilo nthawi zambiri zimakhala zotsika kuposa za mbale zachitsulo zofanana, zomwe zimathandizanso kuti mipope yowotcherera yozungulira ikhale yabwino.
Chofunika kwambiri kukumbukira ndi chakuti, chifukwa chozungulira chozungulira chozungulira chitoliro chozungulira sichimayenderana ndi njira yachitsulo chachitsulo (tsina lake yankho limadalira mbali yozungulira ya chitoliro chachitsulo), pamene chitoliro chowongoka chachitsulo chowongolera chitoliro chachitsulo chikugubuduza. malangizo perpendicular kwa malangizo a zitsulo chitoliro olamulira, motero, ozungulira welded chitoliro zakuthupi ndi bwino kuposa mowongoka msoko zitsulo chitoliro ming'alu kukana.
Njira Yowotcherera
Kuchokera kuwotcherera, ozungulira welded chitoliro ndi molunjika msoko zitsulo chitoliro kuwotcherera njira ndi yemweyo, koma mowongoka msoko welded chitoliro mosalephera kukhala ndi nsonga yowotcherera ding, kotero mwayi kuwotcherera zilema zikuchulukirachulukira, ndi nkhawa yotsalira ya kuwotcherera. pa ding weld ndi yayikulu, zitsulo zowotcherera nthawi zambiri zimakhala zovuta zitatu, zomwe zimawonjezera mwayi wosweka.
Komanso, malinga ndi kumizidwa arc kuwotcherera ndondomeko, aliyense kuwotcherera ayenera kukhala pa arc chiyambi ndi arc kuzimitsa, koma aliyense molunjika msoko welded chitoliro mu welded annular msoko, sangathe kukwaniritsa chikhalidwe, motero pangakhale zambiri kuwotcherera zilema pa arc. kuzimitsa.
