Ib qho ntawm cov yam ntxwv tseem ceeb ntawm peb cov hlau puag ncig yog lawv lub zog tensile tshwj xeeb.Nrog lawv lub peev xwm los tiv thaiv kev ntxhov siab thiab siab, peb cov kab puag ncig muab cov kev daws teeb meem txhim khu kev qha rau cov qauv kev txhawb nqa, cov khoom siv tshuab, thiab cov ntawv thov tseem ceeb uas xav tau cov ntaub ntawv muaj zog thiab ruaj khov.
Tsis tsuas yog peb cov hlau puag ncig cov khoom tsim kho rau lub zog tshwj xeeb thiab kev ua haujlwm, tab sis lawv kuj muaj qhov zoo tshaj plaws weldability.Qhov no txhais tau hais tias koj tuaj yeem koom nrog ob lossis ntau qhov ntawm peb cov kab puag ncig ua ke, tsim kom muaj kev sib txuas ruaj khov thiab ruaj ntseg uas yuav tiv taus qhov kev sim ntawm lub sijhawm.Lub weldability ntawm peb cov kab puag ncig ua kom ntseeg tau tias koj muaj qhov yooj yim los tsim cov txheej txheem nyuaj thiab kev sib dhos, paub tias lawv yuav nyob twj ywm thiab tsis zoo.
