Simbi yepamusoro yekuputira yakagadzirirwa kuita ngura kana kushongedza, kana zvese zviri zviviri.Iyo seam welding, kwete chete kuwana yakakwana yekubatana simba, asi zvakare inodiwa kuchengetedza basa rejasi.Nezvinodiwa zvesimba, seam welding process uye isina kuvharwa simbi yakafanana, uchifunga nezve izvo zvinodikanwa zvekupfeka, welding process parameters ichaita zvigadziriso zvinodikanwa, wozoteerera kukanganiswa kwekubatana kwekupotera, kubvumira iyo electrode indentation, coating uye. mai huni uye simbi alloys kuita kuumba adhesions kuitika pamwe electrodes.

Galvanized steel pipendiko kuwedzera ngura kuramba simbi, asi pashure galvanized nyoro simbi yakaoma kupfuura kwete galvanized simbi ndiro welding.Kunyanya nekuda kweiyo yakaderera kunyungudika kwe zinc coating (inenge 419C), panguva yekushongedza marata layer inotanga kunyungudutswa uye iyo roller nhengo uye welding electrode uye welding nhengo uye yekuonana pamusoro peiyo welding ikozvino kugovera nhengo, iyo yekuonana nzvimbo inowedzera. , iyo yazvino density inodzikira uye iyo yekuonana pamusoro pe electrode uye weldments galvanized layer inonyungudika, uye electrode face bonding, copper electrode alloying (CuZn), ayo magetsi conductivity, thermal performance deterioration.Kuvira kwe zinc 906C, kana tembiricha yadarika iyi tembiricha, kufefeterwa kwe zinc.Kuumbwa kwe pores kana kuputika mu nugget, iyo inopisa nzvimbo yakakanganiswa inopararira mukati mekubatanidza inokonzera embrittlement kuputika kunogona kunge kuri pasi pekumanikidzwa.Miedzo yakaratidza kuti diki chiyero chekupinda (10 - 26%), kushomeka kwekukanganisa kudiki;welding yekumhanyisa yakakwira, mamiriro ekutonhora akashata, kupisa kwepamusoro uye kupinza kwakadzika, kuri nyore kutsemuka.Naizvozvo, kuve nechokwadi cheiyo nugget dhayamita uye majoini simba mamiriro, inofanira kuedza kushandisa diki ikozvino, yakaderera welding kumhanya uye kutonhora kwekunze kwakasimba.Electrodes inofanira kushandiswa embossing roller drum drive, kuitira kuchengetedza chubhu yakatenderedza uye kuchenesa saizi ye electrode.
