Okwekenenya mu bujjuvu enkola z’okuteebereza ku Welder w’ekifo eky’okutereka amaanyi: Performance Leap

Okwanjula

Mu kuweta tabu za bbaatule z’emmotoka ez’amaanyi amapya,...Welder w’ekifo ekitereka amaanyine hemispherical projections eyongera ku maanyi ga weld ne 40%; ekitongole ky’amagye kyatuuka bulungi ku zero-spatter welding of thin-walled titanium alloy parts okuyita mu special-shaped projection design. Emisango gino giraga nti enkula y’okuteebereza (projection shape) ya a Welder w’ekifo ekitereka amaanyisi dizayini ya geometry ennyangu yokka, wabula tekinologiya omutuufu agattaokulungamya ennimiro okuliwo kati, bbalansi y’obugumu (thermodynamic balance)., nerheology y’ebintu. Nga ensonga enkulu esalawo omutindo gw’okuweta, enkula y’okuteebereza ekosa butereevu obulungi bw’okussa essira ku maanyi (okutuuka ku bitundu ebisukka mu 92%) n’obutebenkevu bw’okutondebwa kwa weld nugget. Ekiwandiiko kino kyekennenya mu nkola enkola n’okukozesebwa mu makolero kw’ebika bina ebikulu eby’okuteebereza ku Capacitor Discharge Spot Welders.

I. Omusingi omukulu: Engeri Enkula y’okuteebereza gy’ekosaamu omutindo gw’okuweta

• OmuWelder w’ekifo ekitereka amaanyiategeera okufulumya amasoboza ag’obulagirizi okuyita mu kulaga ku nsonga y’obusannyalazo, era enteekateeka yaayo ey’enkula erina okutuukiriza ebiruubirirwa bisatu:
