Thaum lub sij hawm welding txheej txheem, lub melting qhov tob tshaj lub thickness ntawm lub raj xa dej, thiab cov hlau melting ntws tawm ntawm sab nraum qab ntawm lub vuam los tsim perforation.
(1) Kev puas tsuaj
Nws rhuav tshem qhov ntom ntom ntawm cov vuam thiab qhov poob ntawm kev sib txuas thiab kev muaj peev xwm ntawm cov vuam sib txuas yog qhov tsis xws luag uas tsis tso cai rau muaj nyob rau ntawm cov kav dej siab.
(2) Ua rau kev tsom xam
Lub vuam tam sim no loj dhau, qhov nrawm nrawm dhau, thiab qhov arc nyob ntawm qhov vuam ntev dhau lawm, uas yuav ua rau muaj qhov tsis zoo;
Qhov chaw nruab nrab ntawm cov weld loj dhau lawm, thiab qhov blunt sab yog me me dhau lawm thiab nws yooj yim rau hlawv.
(3) Tswj kev ntsuas
Thaum vuam, xaiv qhov ntsuas kab raws li qhov tuab ntawm cov kav raj xa dej, thiab tom qab ntawd xaiv cov vuam tam sim no raws li qhov ntsuas kab, thiab yuav tsum tau nruab nrog qhov tsim nyog ceev ntawm lub tank;
Ua ntej txiav cov kav dej los ntawm kev txiav. Yog tias cov pa oxygen ib qho hluav taws xob acetomo raug txiav thiab txiav tawm, qhov kev txiav yuav tsum tau polished kom tshem tawm cov pob;
Thaum cov yeeb nkab tawm tsam, qhov sib txawv ntawm qhov sib txuas yog qhov sib xws, thiab tsis loj lossis me dhau;
Ua tib zoo saib xyuas lub sijhawm nres ntawm ob sab ntawm txoj kab nqes.
