Welded yeeb nkab, nyob rau hauv feem ntau qhov teeb meem hu ua weld yeeb nkab, yog cov yeeb nkab steel ua raws li cov hlau phaj los yog siv cov hlau, tom qab kub dov los yog txias dov, coiled thiab tsim rau hauv seem los yog yeeb nkab, ntev feem ntau nyob rau hauv 6m. Case hardening yog qis dua seamless yeeb nkab.
Raws li qhov sib txawv, cov yeeb nkab vuam tau muab faib ua ntau ntau raws li hauv qab no.
Raws li txoj kev welding, ncaj weld yeeb nkab thiab kauv vuam yeeb nkab
Ib txoj kev ua, arc weld yeeb nkab, hytride weld yeeb nkab thiab electrode vuam yeeb nkab
