Danho 1 Simbi Plate Surface Pretreatment

Kuitwa zvinoenderana nedhizaini kana maitiro zvinodiwa pamberi pesimbi yeplate blanking.

Danho 2 Simbi Plate Kururamisa

Kutwasanuka kwakazara kuchaitwa mushure mekutanga simbi ndiro kuti ive nechokwadi chekusavhara uye kudzoreredza mukati kusara kunetseka kwesimbi ndiro.

Danho 3 Kucheka uye Kusavhara kweZvikamu

Usati wacheka, gadzirisa muchina wekucheka, simbisa iyo nozzle modhi, uye tarisa kugadzikana kwemhepo.

Panguva yekucheka, preheat seam yekucheka yeplate yesimbi kutanga, uye nyatso kudzora kumhanya kwekucheka.

Nhanho 4 Kutwasanura Kwechipiri kweZvikamu

Inoitwa mushure mekuvhara ndiro yesimbi kuti ive nechokwadi chekusangana uye kuderedza mukati masara kushushikana kwesimbi mahwendefa.

Nhanho 5 Setting yeJigs uye Layout Lines

Pamberi pegungano, mitsetse yekugadzira uye jigs inofanira kuiswa kutanga.

Panguva yekuiswa kwejig, iyo yakatwasuka yekuvhurika kwepamusoro inofanirwa kuve nechokwadi, uye kuomarara kwakakwana uye kusimba kuchavimbiswa.

Yese jigs uye mitsetse yekumisikidza inogona kungoiswa mukushandiswa mushure mekuongororwa uye kubvumidzwa nevashandi vakasarudzwa.

Nhanho 6 Lower Panel Positioning

Yakamisikidzwa chaizvo neplumb bob uye marongerwo mitsara.

Nhanho 7 Diaphragm Assembly

Madiaphragms asati aunganidzwa, maka mitsetse yekumisikidza pane yepasi, uye bvisa ngura inoyangarara pamativi ese emitsetse nevhiri rekukuya.

Mushure mekunge ma diaphragms agadzikwa, gadzirisa ne tack welding.

Danho 8 Webhu Gungano

Mushure mekunge dandemutande raunganidzwa uye rakakodzera, sunga zvakasimba pa diaphragm nejeki, wozoigadzirisa ne tack welding.

Nhanho 9 Upper Panel Assembly

Zadzisa nzvimbo chaiyo yepaneru yepamusoro ine plumb bob, wobva wagadzirisa ne tack welding.

Nhanho 10 Diaphragm Electroslag Welding

Single-sided electroslag welding inogamuchirwa kune diaphragms.

Sleeve dzemhangura dzearc kutanga nekudzimisa dzinozoiswa kumusoro uye kuzasi kuvhurika kwe electroslag welding maburi panguva yewelding.

Welding ikozvino uye voltage ichave yakanyatso kudzorwa mukati mewelding process, uye kutarisisa kuchabhadharwa pakucherechedza shanduko yemavara enzvimbo ye electroslag welding pawebhu.

Nhanho 11 Kuongorora Kwese

Panguva yekuongorora, tarisa kutarisa kuti urefu hwechikamu, diagonal dimensions uye magumo echikamu chezvikamu zvinosangana nekugadzirwa uye kutsanangurwa kwezvinodiwa, uye kugadzirisa zvikamu zvose zvisingabvumirwi.

Danho 12 Pedzisa Kugaya

Gaya kumeso kwekupedzisira mushure megungano uye welding.

Simbisa kuenzana kwenhengo uye kufanana pakati pechiso chekupedzisira uye chigayo chekucheka.

Danho 13 Kuputika kwejecha uye Kubvisa Ngura

Kubvisa ngura kwakazara nejecha blasting sezvinodiwa mushure mewelding, wozoendesa kune coating kuvaka.

Kururama kwegungano

Panguva yegungano:

● Zvisungo zvakakodzera zvichagamuchirwa kudzora deformation ye welding.

● Zvibvumirano zveWelding shrinkage uye zvinonzwisisika reverse deformation zvichachengeterwa kudzora zvikamu uye kuona chimiro chakarurama.

Kutsauka kunotenderwa kwekugadzira uye kuungana kweakasungwa kubatanidza, pamwe nekushivirira kwedimensional yezvikamu zvezvimiro, zvinoenderana nezvinodiwa zveCode for Acceptance of Construction Quality of Steel Structures (GB 50205).

Assembly positioning welding

Ichaitwa ne semi-otomatiki yakasimba waya gasi simbi arc welding (GMAW).

Welder

Mawelder anopinda mugungano tack welding achabata zvitupa zvinoenderana zvakatsanangurwa muTechnical Specification yeWelding yeBuilding Steel Structures(JGJ81).

Nzvimbo ye tack welds

Position of tack welds: Tack welds inodzivirira kutanga uye kupera kweiyo yakagadziridzwa welds, uye haizoisirwe pamakona, mipendero, kumagumo uye dzimwe nzvimbo dzakakomba dzinosangana nekusimba kwechimiro uye hurema hwekuita.

KumaT-joint, tack welding: Ichaitwa zvakaenzanirana kumativi ose; panguva iyi, tack welding mukati me groove inofanira kudzivirirwa zvakanyanya sezvinobvira.

Kuti uwedzere kupinza giroove welding: Tack welding ichaitwa pamugero we back gouging, e.g., Back gouging.

Nzvimbo dzegungano uye zvekukuchidzira zvewelding backing plates pamwe nerun-on uye run-off plates dzinoenderana nezvinodiwa.

Welding zvinhu

Welding zvinhu zvinoshandiswa kuungana uye tack welding zvichaenderana neizvo zvekushongedza zviri pamutemo, i.e., izvo zvakafanana zvewelding senge zviri pamutemo welding zvichagamuchirwa.

Pamusangano welding pakati pesimbi-yakasimba-simbi uye yakaderera-simba simbi, welding zvinhu zvinofanira kusarudzwa maererano nechepasi-simba simbi giredhi.
