Nyob rau hauv cov txheej txheem ntawm vuam, peb feem ntau ntsib teeb meem teeb meem, tshwj xeeb yog cov ntawv hlau nyias. Peb mas tsuas muaj cov kev daws teeb meem hauv qab no:
(1) Xaiv tsim nyog WELD loj:
Nrog rau kev nce ntawm weld loj, qhov deformation yuav txo qis cov xeeb tsav ntawm lub zog welded, nce kev nyuaj ntawm cov cua sov tuaj yeem ua kom tawg thiab muaj lwm yam tsis xws luag. Yog li ntawd, nyob rau ntawm presife ntawm kev sib ntsib cov xeeb muaj peev ntawm tus vuam zoo, me tshaj weld loj uas yuav raug xaiv nyob rau hauv cov txheej txheem yuav tsum tau raug xaiv nrog cov tuab ntawm lub phaj.
(2) txo qis ntau tus naj npawb ntawm cov ntaub ntawv:
Yog xaiv cov tuab ntawm lub phaj thiab txo cov phaj ntawm tus lej tav, yog li kom txo cov nqi kho vaj tsev thiab post {{}} vuam deformation. Piv txwv li, rau cov qauv siv cov phaj nyias nyias uas siv tau los txo cov kab hlau tav thiab tiv thaiv lossis txo cov posts- vuam deformation.
(3) Qiv li npaj txoj haujlwm Weld:
Cov khoom siv tsis muaj kev ywj pheej tuaj yeem txo yog tias Weld yog qhov zoo rau cov nav ntawm weldment seem lossis weld yog ze rau ntawm nruab nrab ntawm axis.
(4) Muaj kev cia siab shrinkage Allowance:
Lub longitudinal thiab transverse shrinkage deformation ntawm weldment tom qab kev kwv yees weld shrinkage thiab reserving shrinkage lav ua ntej thaum lub sij hawm tsim.
(5) teem sijhawm rau txoj haujlwm ntawm vuam fixture:
Txoj hauj lwm nyob qhov twg lub vuam fixture tuaj yeem nruab tau muab khaws cia yog qhov uas cov khoom siv tau siv los tswj cov kev ua haujlwm ntawm kev siv vuam.
