Zvizhinji zvekuitika kwekutsvaira kwekugadzirisa kunokonzerwa neasymmetry yekupisa inogadzirwa nekuputika uye kuwedzera kunokonzerwa nekupisa kwakasiyana. Iye zvino takarongedza nzira dzinoverengeka dzekudzivirira welding deformation sezvinotevera kuti titarise:
1. Deredza nzvimbo ye-cross-sectional ye weld uye shandisa saizi diki yebevel (angle uye gap) zvakanyanya sezvinobvira uchiwana yakakwana uye pasina kukanganisa kunopfuura mwero.
2. Shandisa nzira yewelding nediki yekupisa. Zvakadai se: CO2 gasi inodzivirira welding.
3. Shandisa multi-layer welding pane imwe-layer welding pese pazvinogoneka pakusecha mahwendefa akakora.
4. Kana izvo zvinodiwa zvekugadzira zvasangana, iyo welding ye longitudinal reinforcement mbabvu uye transverse yekusimbisa mbabvu inogona kuitwa nepakati welding.
5.Kana mativi ose ari maviri achigona kusungirirwa, mabheji akaenzana maviri-sided symmetrical anofanirwa kushandiswa, uye welding sequence inoenderana neyakarerekera uye axial components inofanira kushandiswa panguva yakawanda-layer welding.
6. Kana iyo T-yakaita yejojo ndiro yakakora, yakavhurika bevel angle butt welds inoshandiswa.
7. Shandisa nzira ye-anti-deformation musati welding kuti udzore kushanduka kweangular mushure mekuputika.
8. Shandisa rigid fixture fixture kudzora post-weld deformation.
9. Shandisa nzira yakachengeterwa kureba kwechikamu kuti utsivise kureba kwekureba uye deformation ye weld. Semuenzaniso, 0.5 ~ 0.7 mm inogona kuchengetwa pamamita eH-shaped longitudinal weld.
10. Kukanganisa kwenhengo refu. Iyo inonyanya kuvimba nekuvandudza kupfava kwebhodhi uye kurongeka kwegungano kwezvikamu kuita kuti bevel angle uye clearance ikwane. Iyo dhizaini kana pakati pearc ndeyechokwadi kuitira kuti weld angle deformation uye longitudinal deformation kukosha kwebapiro uye webhu kuenderane nehurefu kutungamira kwechikamu.
11. Paunenge uchiputira kana kuiswa kwezvikamu zvine welds yakawanda, inonzwisisika welding sequence inofanira kugamuchirwa.
12. Paunenge uchipinza ndiro dzakatetepa, shandisa mumvura-welding. Iko ndiko kuti, dziva rakanyungudutswa rakakomberedzwa negasi rekudzivirira mumvura, uye mvura iri pedyo inobviswa zvachose kubva mugasi kuti ione kuti kusungirirwa kunoitwa kazhinji. Nokushandisa nzira iyi, simbi yakatenderedza dziva rekunyunguduka yakasimba inotonhodzwa nemvura munguva, uye deformation uwandu hunodzorwa kusvika pamwero muduku zvikuru (inotenderera inotonhorera inowedzerwa pakatarisana nowelding divi kuti abvise kupisa kunogadzirwa ne welding).
13. Multi-stage symmetrical welding, kureva, welding imwe chikamu, mira kwechinguva, welding kune rumwe rutivi, kumira kwechinguva.
