Daim ntawv thov ntawm vuam neeg hlau tau coj tau nyiaj zoo heev rau qhov chaw vuam vuam, vim hais tias vuam neeg hlau yooj yim rau kev khiav lag luam thiab kev ua haujlwm tau zoo yog 3 zaug ntawm cov neeg ua haujlwm ib txwm muaj. Vuam neeg hlau yuav tuaj yeem tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm vuam. Vuam neeg hlau muaj kiag li hloov kev tuav haujlwm. Cov neeg siv hlau vuam siv cov argon-nplua nuj sib xyaw ua ke cov pa roj thaiv vuam. Cov vuam tsis zoo uas tshwm sim thaum lub sijhawm ua haujlwm vuam feem ntau suav nrog ua haujlwm vuam kev ua haujlwm tsis sib xws, ua haujlwm qis, thiab qhov hws. Cov kev tshuaj ntsuam tshwj xeeb yog li nram no:
(1) Qhov tshwm sim ntawm vuam sib txawv yuav yog los ntawm qhov chaw tsis muaj vuam los yog teeb meem thaum tshawb lub vuam phom. Lub sijhawm no, nws yog qhov yuav tsum tau txiav txim siab seb TCP (qhov chaw ntawm nruab nrab qhov chaw nruab nrab ntawm lub vuam phom) puas raug thiab kho nws. Yog tias qhov no tshwm sim tas li, xyuas qhov xoom ntawm txhua lub axis ntawm tus neeg hlau, thiab rov ntsuas qhov ntsuas nws kom raug.
(2) Qhov tshwm sim ntawm undercut yuav yog vim txoj kev xaiv tsis zoo ntawm vuam tsis, vuam tsau teeb lub kaum sab xis lossis vuam tsau txoj haujlwm. Koj tuaj yeem tsim kho kom haum rau lub zog los hloov lub vuam kev ntsuas, kho qhov hluav taws xob posture thiab qhov chaw sib piv ntawm cov vuam txuas thiab lub chaw ua haujlwm.
(3) Lub chaw ua kom zoo yuav yog vim kev tiv thaiv roj tsis zoo, lub hauv paus ntawm lub workpiece yog tuab heev, lossis cov roj thaiv tiv thaiv tsis tau qhuav, thiab nws tuaj yeem raug dealt los ntawm kev kho kom haum.
(4) Ntau dhau ntawm qhov tsis tuaj yeem yuav yog vim xaiv qhov tsis zoo ntawm lub vuam tsis haum, roj sib xyaw vim li cas, lossis ntev dhau mus ntev ntawm txoj hlua hlau tsis txuas. Koj tuaj yeem hloov kho lub zog los hloov lub vuam kev hloov kho, kho qhov ntsuas cov pa roj kom kho qhov sib xyaw roj sib xyaw, thiab kho lub vuam phom thiab qhov phom sij ntawm qhov chaw ua haujlwm.
(5) Kev tsim hluav taws xob arc yog tsim nyob rau qhov kawg ntawm lub hlau txuas tom qab txias, thiab qhov nqus dej hauv av arc crater muaj peev xwm ntxiv rau cov theem ua haujlwm thaum lub sijhawm sau los sau nws.
