Copper tube welding
Kev vuam ntawm cov raj tooj liab feem ntau siv 50%, 45%, 35% lossis 25% nyiaj vuam rods, txhua yam yuav tsum muaj kev txav mus los zoo thiab kev pab cuam ntawm flux. Cov flux siv yuav tsum yog ib qho yooj yim sib tov los yog hmoov.
Carburizing nplaim yog siv rau tooj liab raj vuam. Cov txheej txheem welding yog:
(1) Ua ntej cua sov, siv flux rau qhov yuav tsum tau welded.
(2) Thaum tshav kub kub thiab ntxig rau lub raj tooj liab thiab lub tes tsho, thiab txav cov nplaim taws rov qab los ntawm ob lub ntsiab lus tsis tu ncua. Tsis txhob cia cov nplaim taws ncaj qha mus kov cov flux. Qhov kub thiab txias thaum cua sov lub raj hlau yog me ntsis siab dua li thaum cua sov lub raj tooj liab.
(3) Thaum lub raj tooj liab tau rhuab thiab cov flux melts mus rau hauv cov kua, tam sim ntawd muab lub preheated vuam pas nrig rau ntawm qhov chaw vuam. Thaum lub vuam pas nrig pib yaj, txav cov nplaim taws rov qab los ntawm ob mus txog rau thaum lub vuam ntws mus rau hauv qhov sib txawv ntawm ob lub raj.
(4) Tshem tawm cov nplaim taws, cia lub solder hu rau qhov chaw vuam, thiab khaws cia rau ob peb feeb ua ntej tshem tawm. Yog tias nws xav tias lossis pom tias tseem muaj qhov chaw nruab nrab ntawm ob lub raj, koj tuaj yeem ua kom sov nws dua thiab txav cov nplaim taws tsis tu ncua ntawm ob lub ntsiab lus. Yog tias tsim nyog, ntxiv me me ntawm solder.
