Kev ua haujlwm ntawm cov kav dej tsis siv neeg vuam tshuab kuj yog cov txheej txheem uas simulates phau ntawv vuam. Lub raj xa hluav taws xob ntawm cov tshuab vuam tsis siv neeg hloov cov haujlwm uas tau ua los ntawm txhais tes mus rau hauv cov khoom siv tshuab. Peb paub tias nyob rau hauv tus txheej txheem ntawm phau ntawv welding, thaum peb hloov cov welding rods ntawm peb tus kheej, tsis sib xws welds yuav inevitably tshwm sim, thaum tsis siv neeg vuam Lub tshuab paub qhov nruam vuam los ntawm kev hloov cov vuam rods, uas tsis tsuas yog zoo heev txhim kho kev ua hauj lwm efficiency, tab sis kuj ua rau cov weld zoo ruaj khov. Kev ua haujlwm ntawm cov kav dej tsis siv neeg vuam tshuab yog roughly muab faib ua: pipeline bevel processing - yeeb nkab sib dhos - hauv qab vuam - filling - cap vuam.
Raws li txoj kev loj hlob sai ntawm kev lag luam tsheb thauj mus los tau coj ntau thiab ntau dua kev pab rau tib neeg lub neej, pipeline vuam thev naus laus zis kuj tau ua rau muaj txiaj ntsig zoo, txij li yav dhau los welding mus rau downward vuam. Semi-automatic welding thiab tag nrho tsis siv neeg vuam kuj ua ntau thiab nyuaj. Nyob ntawm qhov nruab nrab ntawm kev sib kis, xws li: cov raj xa hluav taws xob, cov kav dej roj, cov kav dej thermal, cov kav dej hluav taws xob, cov roj thiab cov kav dej sib xyaw ua ke, thiab lwm yam. Kuj tseem muaj qee qhov sib txawv ntawm cov txheej txheem vuam cov txheeb ze.
