    Peb lub kauvcov kav dej vuamyog tsim nrog kev saib xyuas. Pib nrog cov hlau strips lossis cov phaj dov, peb khoov thiab deform cov ntaub ntawv no rau hauv lub voj voog. Tom qab ntawd peb vuam lawv ua ke los ua ib lub yeeb nkab muaj zog. Los ntawm kev siv ntau txoj kev vuam xws li arc welding, peb lav qhov zoo tshaj plaws lub zog thiab durability ntawm peb cov khoom.
