(1) nrog lub zog-oriented wedge interface rau welding non-crystalline yas, thiab semi-crystalline yas, vuam zoo yog pluag. Raws li cov yas semi-crystalline hauv lub cev ntawm cov dej ntws ntws tawm kuj yog qhov nqaim, cov hluav taws kub-taw qhia tau yooj yim sai sai tom qab kho, tsis yooj yim mus kis rau tag nrho interface, uas ua rau thaj tsam ntawm lub zog-taw qhia vedge rau daim velds, vuam lub zog Heev tsawg
(2) Lub txaj interface yog ntau hom ntawm interfacial semi-crystalline yas. Nyob rau hauv cov txheej txheem welding, pib sib txuas nrog cov khoom siv hauv zos, thiab tom qab ntawd ntxhua hauv ob qho ntawm cov kev cuam tshuam ntawm kev sib nrauj ntawm cov ntaub ntawv, nyob rau hauv siab, ob feem ntawm txoj kev taug mus rau hauv lub zes ua ke, qhov interface hauv tib txoj kev Tsim nyog rau cov yas uas tsis yog crystalline, thiab qhov tseem ceeb tshaj plaws rau cylindrical qhov chaw, thiab tuaj yeem tsim ib lub zog ntawm airtight welding.
(3) Lub miter interface kuj yog tsim rau cov yas semi-crystalline, vim hais tias melting txheej txheem tshwm sim nyob rau ntawm qhov interface, tsis txhob cia cov ndlwg ntawm cov hlau yas, feem ntau siv rau hauv cov ntaub ntawv ntawm nyias qhov chaw, cov interface yog ncig lossis lub qij 'voj' contour Cov khoom kom tsis txhob haum thiab tiv tauj cov teeb meem ntawm lub ces kaum ntawm txoj kev nce roob.
