Yuav ua li cas qhia qib ntawm vuam hlau: Vuam hlau muaj xws li carbon hlau rau vuam, hlau alloy hlau rau vuam, stainless hlau rau vuam, thiab lwm yam. Txoj kev qhia cov qib yog ntxiv cov cim "H" rau lub taub hau ntawm txhua hom. welding steel qib. Piv txwv li, H08, H08Mn2Si, H1Cr18Ni9. Rau cov qib high-zoo welded steel, ntxiv cov cim "A" tom kawg ntawm qib. Piv txwv li, H08A, H08Mn2SiA.

Feem ntau sivwelded steel kavtau muab faib ua peb hom hauv qab no raws li cov txheej txheem vuam siv hauv lawv cov khoom.
① Nruam rauv welding (forge welding) steel yeeb nkab: Nws yog tus cwj pwm los ntawm kev ua haujlwm siab thiab cov nqi tsim khoom tsawg, tab sis kev sib xyaw ua ke ntawm cov welded tsis tiav, qhov vuam zoo tsis zoo, thiab cov khoom siv dav dav tsis zoo.

② Resistance welded steel yeeb nkab: Nws yog tus cwj pwm los ntawm kev ua haujlwm siab, qib siab ntawm automation, tsis xav tau vuam rods thiab flux thaum lub sij hawm vuam, me ntsis kev puas tsuaj rau lub hauv paus hlau, thiab me me deformation thiab residual kev nyuaj siab tom qab vuam. Txawm li cas los xij, nws cov khoom siv ntau lawm yog qhov nyuaj, cov cuab yeej siv cuab yeej cuab tam yog siab, thiab qhov kev xav tau zoo ntawm cov pob qij txha welded kuj tseem siab.

③Arc welded steel yeeb nkab: Nws cov yam ntxwv yog tias cov welded sib koom ua tiav kev sib koom ua tiav metallurgical, thiab cov khoom siv sib txuas tuaj yeem ncav cuag lossis nyob ze rau cov khoom siv ntawm cov khoom siv hauv paus. Raws li cov duab ntawm cov welded, arc welded steel kav yuav muab faib ua ncaj seam kav thiab kauv welded kav; Raws li kev tiv thaiv sib txawv siv thaum vuam, arc welded steel kav yuav muab faib ua submerged arc welded steel kav thiab melting arc welded steel kav. Muaj ob hom welded steel kav.
