Sei yemagetsi-welded simbi nenyere?

Apo nenyere inoshandiswa nhasi, Steel yemagetsi-welded? chigadzirwa ichi, izvo mamiriro ano zvinowanzoshandiswa maindasitiri akasiyana-siyana.

kunyoresa

Kazhinji, anoiswa apo zvakakodzera kutakura mvura kana gaseous fuma rurefu mwero sehasha. Naizvozvo, chubhu iri mhando anogona kuwanikwa engineering, paakapa huru kudziyisa rukoko.

Electric-welded simbi mutopota zvaishandiswa indasitiri. Pasina izvozvo haugoni kuita nemafuta, pakuvaka rwemichinjiko, ari zvaAtemisi midziyo kana mutambo vanodzidzisa. pakawanda Its, zvakanaka kuita, mikana yakanaka Welding (kusanganisira musha) unogona kurishandisa nderemagariro kuti paumbwe uye kugadziridza engineering network.

Electrically welded Zvikwepa simbi, ine GOST 10704-91 nhamba, berekai zvimwe kurongwa kureba kwenguva imwe dhayamita. Somuenzaniso, kana wokupedzisira kukosha 0.3 masendimita chigadzirwa hakufaniri pe2 metres refu, uye kana iri kupfuura 15.2 cm kureba haagoni kuva zvishoma pane 5 m. Uyewo, pane ndeiya yakaita zvakasiyana kana kureba kwenguva vakapiwa dhayamita nenyere ari mumwe siyana. Saka, nokuti chinoratidza kuti 7 masendimita saizi nyaya Ingasiyana kubva 5 kusvika 9 mamita.

kugadzirwa

Chii ehupfumi kwakadaro nyere vanofanira? Steel yemagetsi-welded nadzurudzo pakuburitswa vanofanira kuva zviruva kuti panguo ehurumende zvinodiwa kuti nyaya akashandiswa ichi kana kuti bhora. Somuenzaniso, zvikwepa chemafuta gasi mapaipi (hunde) zvinoitwa maererano GOST 20295-85. Vari inoumbwa chakanamwa nomoto chinhu chakakombama kana kuonana mhando (ekupedzisira dzakakwirira-kakawanda dzenzvimbo) nedzimwe simba makirasi (kubva K34 kuna K60).

Nokuti kugadzirwa mishonga inoshandiswa kana thermally kurapwa inopisa anokungurutsirwa simbi (vagadzikana kana Semi-kuurayiwa) pamwe zviri C (kabhoni) haasi kupfuura 0.2% uremu. machira ayo akanga coiled they chubhu, pashure iyo micheto machira vadziyirwa uye kuitika vaipisa mabhanzi (electrode marin'i). Mwero pezvakaitwa zvakadaro dzinokosha michina inogona kunyatsonanga yakakwirira (makumi ezviuru metres paminiti pamusoro nomoto, zvichienderana parusvingo ukobvu). Operation ari inenge nguva dzose pamwe nokuveza zvibereko achida urefu achishandisa slotted michina.

Steel yemagetsi-welded kuwana kupisa kurapwa akafanana yose kureba, uye chete ari weld. On mujinga zvigadzirwa zvesimbi havabvumirwi dzamakatapa, zvaunokanganisa, makatsemuka, kuvira kwezuva uye mwanda. chinogamuchirika chechetere pamusoro zvikanganiso havafaniri kurairirwa Welding (chete nomutsvairo) kuti tirambe runodiwa mwero chigadzirwa rakavimbika. Welded majoini havafaniri murombo Fusion, makatsemuka, pores, fistulas, gang inclusions anouya pemvura.

Kana toreva mapaipi mugwagwa simbi electrically welded? The mutengo wavo, zvichienderana mugadziri, iyo simbi giredhi, kuti dhayamita uye rusvingo ukobvu anogona dzinosiyana 32 kusvika 45-48 zviuru. Kana kutenga unofanira kuteerera nguva dzose kuti zvaidiwa hurumende mitemo, kuti ndiye. To. In ayo framework, zvigadzirwa zvakaitika runodiwa nemiedzo, kusanganisira chimwe chezvinonhuwira fura, zvakamubaya simba panguva tembiricha siyana, kuti tensile kuti denderedzwa nyaya, kureba kutsauka, simbi unhu welded vagari, uye vamwe.

Nokuti mashoko chii chigadzirwa iri vakaronga kutenga, vanogona kudzidza kubva mucherechedzo pamusoro chubhu. Zvinofanira hako kutakura ari chinhambwe 10-150 masendimita kubva kumugumo mumwe, kwakaratidzwa nomuti uye anosanganisira gore gadzira, unyanzvi kuzvidzora data, iyo simbi giredhi, munhu wacho nyere nhamba (batch mangé), kuti vanozivikanwa ari mugadziri.
