Weld leveling yeyakatwasuka seam simbi pombi (lsaw/erw):

Nekuda kwekukanganisa kweiyo welding ikozvino uye pesvedzero yegiravhiti, iyo yemukati weld yepombi ichabuda, uye yekunze weld ichadonhawo. Kana matambudziko aya akashandiswa munzvimbo yakajairwa-yakadzika-kudzvanywa kwemvura, haazokanganiswe.

Kana ikashandiswa mukupisa kwepamusoro, kudzvanywa kwepamusoro uye kumhanyisa kwemvura nharaunda, zvinokonzeresa matambudziko mukushandiswa. Uku kukanganisa kunofanirwa kubviswa uchishandisa yakatsaurwa weld leveling michina.

Nheyo yekushanda yewelding seam leveling equipment ndeye: mandrel ine dhayamita ye 0.20mm idiki pane yemukati dhayamita yepombi inoiswa mupombi yakashongedzwa, uye mandrel yakabatana necylinder kuburikidza netambo yewaya. Kuburikidza nekuita kweiyo cylinder yemhepo, iyo mandrel inogona kutamiswa mukati menzvimbo yakatarwa. Mukati mehurefu hwemandrel, seti yekumusoro uye yakaderera mipumburu inoshandiswa kukungurusa weld mune inodzokorodza motion perpendicular kune chinzvimbo che weld. Pasi pekumanikidzwa kwe mandrel uye roll, maprotrusions uye depressions zvinobviswa, uye contour ye weld uye pombi contour inoshandurwa zvakanaka. Panguva imwecheteyo sekugadziriswa kwewelding, iyo yakaomesesa zviyo chimiro mukati meweld inomanikidzwa, uye ichaitawo basa mukuwedzera kuwanda kweiyo weld chimiro nekuvandudza simba.

Weld leveling sumo:

Munguva yekuputika-kupeta kwesimbi yesimbi, kuoma kwebasa kuchaitika, izvo zvisingakodzeri kune post-processing yepombi, kunyanya kukotama kwepombi.
Munguva yewelding process, yakaomesesa zviyo chimiro chinozogadzirwa paweld, uye pachave newelding stress paweld, kunyanya pakubatana pakati peweld ne base simbi. . Kupisa midziyo yekurapa inodiwa kuti ibvise kuoma kwebasa uye kunatsa chimiro chezviyo.
Parizvino, iyo inowanzo shandiswa yekupisa kupisa maitiro ndeye yakajeka mhinduro kurapwa mune hydrogen inodzivirira mamiriro ekunze, uye pombi yesimbi isina tsvina inopisa kusvika pamusoro pe1050 °.
Mushure menguva yekuchengetedzwa kwekupisa, chimiro chemukati chinoshanduka kuita chimiro cheuniform austenite, iyo isingaite oxidize pasi pekuchengetedzwa kwehydrogen atmosphere.
Midziyo inoshandiswa ndeye online inopenya mhinduro (annealing) midziyo. Midziyo yacho yakabatana neiyo roll-bending forming unit, uye iyo welded pombi inoiswa kune yakajeka mhinduro kurapwa online panguva imwe chete. Midziyo yekudziya inotora yepakati frequency kana yakakwira frequency magetsi ekudziya nekukurumidza.
Taurira yakachena hydrogen kana hydrogen-nitrogen mamiriro ekudzivirira. Kuomarara kwepombi yakavharwa inodzorwa pa180±20HV, iyo inogona kusangana nezvinodiwa zvepashure-kugadzirisa uye kushandiswa.
