Iyo mafuta casing ipfupi yakabatana, zvichikonzera chiitiko ichi nekuda kwekutadza kwemukati mekinika senge roller kana shaft eccentricity, kana yakawandisa welding simba, kana zvimwe zvikonzero. Sezvo kumhanya kwewelding kunowedzera, iyo chubhu isina extrusion kumhanya inowedzera. Izvi zvinogonesa extrusion yemvura simbi akaturikidzana uye oxides yave kudziyisa kunyunguduka kune yepamusoro mhando weld. Panguva imwecheteyo, kuwedzera kumhanya kwewelding kunogonawo kuderedza nguva yekupisa ye groove pamusoro, kuitira kuti dunhu diki remafuta rigone kupfupiswa uye kupisa kunokanganisa nzvimbo inogona kuderedzwa.

Kusiyana neizvi, kwete chete kupisa kwakakanganiswa nzvimbo yakafara, asiwo yakatetepa yesimbi yesimbi main compound inoumbwa pamusoro pegorofu inova gobvu, uye mabhuru mahombe anogadzirwa, ayo anokanganisa kunaka kweiyo weld. Nekudaro, pane rimwe simba rekubuda, iyo inotonhora welding kumhanya haigone kuwedzerwa pasina kuganhurirwa. Zvikasadaro, kupisa kwemativi ese ebillet groove hakuzosviki tembiricha yewelding, kuitira kuti pave nekuremara kana kusave welding zvachose.

Kune simbi isina tsvina, iyo pfupi yakabatana ripple coefficient yemafuta inokanganisa kuumbwa kwewelds. Capacitance kusefa kunoderedza ripple kusvika pasi pe1%. Kana welding simbi isina tsvina, iyo frequency inowanzo 200 welds ine kusimba kwakanaka uye yakakwirira frequency kupisa kwakakanganiswa nzvimbo. . Kazhinji, madziro emukati nekunze epombi yakashongedzwa yakapfapfaidzwa kumashure kubva kunzvimbo yewelding. Mafuro ari pakati nepakati, anoenderera mberi akanaka pakupa pfungwa yekuti simba rewelding rakakwana uye mamiriro emuchina haana kuenzana uye furo rakasvibira welding mamiriro haana kuenzana uye mhando yeweld haina kunaka.
