Ko te tukatuka o te flange kowiri tira me maarama me te aro ki nga raru e whai ake nei:
1, kohakore te weld: he kowiri tira flange fehokotaki'anga kohakore he nui ake, ki te he ki te whakamahi i te tikanga maimoatanga huri mīhini ā-ki te hanga ake, ka nga tohu huri, hua i roto i te mata pāhiwihiwi, ka pā te ahua;
2, oro me te oro hāngū e kore he ōrite: pickling passivation maimoatanga i muri i huri ā-ringa me te oro, mo te wāhi workpiece nui, he uaua ki te whakatutuki pānga maimoatanga ōrite, e kore e taea te tiki i te mata kākahu pai. Kei a ia ano te kino o nga utu tangata-haora, he nui ake nga utu taputapu;
3, he uaua ki te tango rakuraku: pickling passivation whānui, i roto i te aroaro o te reo ha'iriiri ka puta te waikura matū te waikura hiko ranei me te waikura, e kore hoki e taea te tango e tika ana ki te rakuraku, fehokotaki'anga splash me piri ki te mata o te kowiri tira waro maitai, splash me ētahi atu poke;

Na me pehea te whakaoti i te raru o te tukatuka flange kowiri tira?
1, tīpakohia te paraikete, i muri i te otinga, ki roto i te tukanga e whai ake nei, he rereke nga mea mahi kowiri tira kia rite ki nga whakaritenga tukatuka ki te tukanga e rite ana;
2, piko ki te tuatahi i runga i te rahi, kia rite ki te tuhi kowiri 304 matotoru rauemi ngongo maitai ki te whakatau i te piko ki te maripi me te maripi waka, karo hua ki te tapahi tukinga taputapu meinga deformation ko te kī ki te aratau whiriwhiri (i roto i te taua hua, kia whakamahi tauira rerekē o runga mate), me te kōwhiringa o te mate raro whakaritea rite ki te matotoru o te mahere.
3, kia u ai te welding, ki runga ki te waahi whao whao, ka taea te hanga i nga puku ki mua o te whakapiri hiko me te paraharaha o te pereti, kia rite ai te rite o ia waahi ki te wera, ka taea te whakatau i te tuunga weriweri i te wa ano, te hiahia mo te whakapiri, ki te whakatika i te waa o mua, te wa pupuri, te pupuri i te waa me te waa okiokinga, ka taea e taatau te whakarite i te waa mahi.
