Submerged arc kauv welded raj rau roj kab
Muab kauv kav hlau welded yog tsim tawm tsis tu ncua thiab tuaj yeem ua rau kev ua haujlwm ntxiv ua cov kav hlau tsis txaus. Qhov txheej txheem ntau lawm minimizes lub taub hau thiab tus ntsia hlau txiav los ntawm kev siv hlau siv los ntawm 6% rau 8%. Qhov no yuav ua rau cov nyiaj txuag thiab cov khoom siv tau rau peb cov neeg siv khoom.
Peb liMuab kauv welded leegKev muab cov haujlwm zoo tshaj tawm piv rau cov leeg ncaj ncaj rau kev sib tw welded kav. Yooj yim rau sib pauv tawm thiab kho ntau yam, ua rau lawv zoo tshaj plaws rau cov phiaj xwm uas xav tau kev yoog raws thiab raug kho. Ib qho ntxiv, kev siv tshuab thiab kev siv hluav taws xob muaj peev xwm tso cai rau lawv kom nws yooj yim siv rau hauv ntau qhov chaw muaj kev lag luam.
