Qhov zoo ntawm cov yeeb nkab khoob yog qhov tseem ceeb hauv kev txiav txim siab qhov zoo ntawm qhovseamless yeeb nkab.Txhawm rau lav qhov tsim nyog kev vam meej ntawm cov txheej txheem perforation thiab tau txais cov kav dej seamless zoo, cov kev cai nruj yuav tsum tau ua rau ntawm cov duab geometry, cov qauv qis thiab lub xeev ntawm cov yeeb nkab tsis muaj.

Yog hais tias txoj kab uas hla ntawm lub raj dawb paug yog loj dhau los yog lub ellipse loj dhau lawm, qhov tom thaum lub sij hawm perforation yuav deteriorated, thiab sab hauv folding yuav tshwm sim vim lub compression ntau dhau ntawm lub raj dawb paug txoj kab uas hla.

Internal lub koom haum yog hais txog shrinkage thiab central porosity, tsub zuj zuj ntawm non-metallic inclusions, thiab roj cov ntsiab lus.Qhov hnyav ntawm qhov kev xav tau no txawv nrog kev siv cov kav dej seamless thiab hom hlau.

Qhov tseem ceeb tshaj plaws yog qhov zoo ntawm lub raj dawb paug, vim hais tias lub raj dawb paug yog coj mus rau seamless raj ntawm cov khoom nyob rau hauv txhua lub nroog cov neeg xiam oob khab, thiab qhov chaw uas cov neeg xiam oob khab feem ntau tshwm sim los ntawm kev ntxhov siab, cov yas deformation yuav ua rau cov neeg xiam oob khab. xiam oob qhab tob thiab ntev.

Ua kom tiav, txhawm rau tsim cov khoom lag luam zoo seamless yeeb nkab, nws yog qhov tseem ceeb tshaj plaws los xyuas kom meej cov yeeb nkab zoo.
