Kev Ntim Khoom: lub thawv ntoo, lub thawv ntawv Tsis txhob muab sib txuas ntawm qhov r ntawm lub hau tais, uas yuav txo qhov nyias thiab kev ntxhov siab siab. Thaum muab sib txuas, qhov kev xav tau ntawm kev sib txuas tsuas yog tso cai rau radial thiab circumferential. Lub hau loj tuaj yeem tshem tawm qhov kev xav tau no yav tom ntej. Qhov deb ntawm kev sib txuas yuav tsum tau ua, uas yog ntau dua 3δ thiab tsis tsawg dua 100mm (cheeb tsam cuam tshuam los ntawm cua sov vuam yog thaj chaw muaj kev ntxhov siab siab, thiab cov tshuaj lom neeg hauv thaj chaw no yuav raug hlawv. Yog li ntawd, nws yog qhov tsim nyog kom tsis txhob muaj thaj chaw muaj kev ntxhov siab siab, uas cuam tshuam nrog tuab. .Raws li kev paub dhau los, qhov ntev ntawm kev ntxhov siab poob qis yog ntau dua 3δ thiab tsis tsawg dua 100mm). Txawm li cas los xij, nws nyuaj rau cov khoom siv tub yees kom ua tau raws li qhov kev xav tau no thiab muaj nws qhov tshwj xeeb.

Tom qab splicing, lub taub hau spliced ​​thiab spliced ​​​​weld yuav tsum tau kuaj 100% ray lossis ultrasonic, thiab qib kev tsim nyog yuav ua raws li lub plhaub khoom siv. Qib kev tshuaj xyuas thiab piv ntawm qhov kawg tsim weld seam yog tib yam li lub plhaub khoom siv, uas yog pov tseg heev. Piv txwv li: Yog tias lub plhaub khoom siv tau kuaj 20%, III tau tsim nyog. Lub bulkhead splicing weld thiab qhov kawg weld kuj yog III tsim nyog, thiab qhov sib koom ua ke coefficient yog 0.85;
Yog tias lub tsev khoom siv raug kuaj 100%, II tau tsim nyog. Qhov vuam bulkhead splicing thiab qhov vuam kawg kuj yog II tau tsim nyog, thiab qhov sib koom ua ke ntawm kev vuam yog 1
Yog li ntawd, txawm hais tias qhov bulkhead splicing yog 100% sim, qib kev tsim nyog txawv, thiab nws ua raws li lub plhaub khoom siv.
Tab sis xyuam xim rau cov txheej txheem tsim khoom:
Txoj kev raug yog: blanking (scribing) - cov phaj me me raug sib sau ua ke rau hauv cov phaj loj - tsim - kev sim tsis puas tsuaj
Yog tias nws tsis yog qhov kev sim ua ntej molding, qhov zoo ntawm cov khoom tom qab molding tsis tuaj yeem lav. Uas yog hais tias, kev sim tsis puas tsuaj txhais tau tias kev sim tsis puas tsuaj zaum kawg.
