Cov Kav Dej Welded Loj Txoj Kab uas hla Kauv
Khoom piav qhia:
Peb cov kav dej sib txuas ua ke yog ua los ntawm kev dov cov hlau tsis muaj carbon lossis cov hlau tsis muaj alloy rau hauv cov raj ntawm lub kaum sab xis helix tshwj xeeb, hu ua lub kaum sab xis tsim. Cov kab sib txuas ntawm cov kav dej ces raug vuam kom zoo kom tsim tau cov khoom ruaj khov thiab txhim khu kev qha. Ib qho ntawm cov yam ntxwv sib txawv ntawm peb cov kav dej sib txuas ua ke yog nws lub peev xwm los tsim los ntawm cov hlau nqaim kom tsim cov kav dej sib txuas loj.
Cov nocov kav dej loj uas vuammuaj ntau yam kev siv, tshwj xeeb tshaj yog hauvtxoj kab dej phwj tuajPeb cov yeeb nkab uas sib txuas ua ke muaj zog thiab tiv taus xeb, ua rau nws zoo tagnrho rau cov kav dej phwj uas xav tau kev daws teeb meem ntev thiab ua haujlwm tau zoo. Txawm hais tias nws yog cov dej khib nyiab hauv nroog lossis kev tswj cov dej khib nyiab hauv kev lag luam, peb cov yeeb nkab muab kev txhawb nqa thiab kev ua haujlwm ruaj khov.
