Lub vuam qog hais txog vuam hlau nrog ntxiv welded seams. Qhov loj ntawm qhov vuam qog ua rau qhov sib txawv ntawm qhov vuam, thiab qhov chaw muaj kev ntxhov siab yog tsim ntawm qhov sib koom ua ke. Qhov kub ntawm lub pas dej molten yog siab dhau lawm thiab lub solidification qeeb. Kev poob rau hauv kev cuam tshuam ntawm cov dej hlau tuaj yeem tsim cov qog welding. Nyob rau hauv txoj kab nqes, qhov vuam ntawm txoj kab nqes, vuam lossis ntsug vuam. Yog tias qhov vuam tam sim no loj dhau, lub kaum sab xis ntawm lub kaum sab xis tsis raug lossis kev ua haujlwm tsis zoo thiab nws yooj yim los tsim qhov tsis xws luag.
Thaum lub sij hawm tsim cov txheej txheem ntawm cov kauv raj, cov kev ntsuas hauv qab no tuaj yeem raug coj los tswj:
1. Thaum qhov qis ntawm lub pas dej molten tshwm "lub plab me me", nws tuaj yeem tswj tau los ntawm viav vias thiab xaiv lub arc.
2. Thaum lub vuam vuam los yog kev sib koom ua ke, cov vuam tam sim no yuav tsum raug txo kom tsim nyog tshaj qhov vuam vuam. Thaum viav vias sab laug thiab sab xis, taug kev nrawm dua ntawm qhov nruab nrab, thiab ob sab qeeb me ntsis.
3. Thaum cov welded welding tin yog ntxiv dag zog rau cov welded pob qij txha, cov vuam ntawm 3.2 hli yuav tsum tau xaiv, thiab cov vuam tam sim no yuav tsum raug txo kom tsim nyog.
