Cov ntsiab lus tseem ceeb ntawm stainless hlau yeeb nkab vuam
1. Siv lub hwj huam hluav taws xob nrog cov yam ntxwv sab nraud ntawm qhov ntsug, thiab siv qhov zoo j thaum DC (xaim hlau txuas rau qhov tsis zoo j).
2. Feem ntau haum rau vuam daim hlau hauv qab 6 hli, nrog cov yam ntxwv ntawm vuam zoo nkauj zoo nkauj thiab vuam me me tsis txawv.
3. Cov roj av tiv thaiv tau argon nrog qhov ntshiab huv ntawm 99.99%. Thaum lub vuam tam sim no yog 50 ~ 50A, cov khoom ntws argon yog 8 ~ 0L / min, thaum lub sijhawm tam sim no yog 50 ~ 250A, cov khoom ntws argon yog 2 ~ 5L / min.
4. Qhov kev tawm tsam ntev ntev los ntawm tungsten j los ntawm lub taub roj yog qhov zoo dua 4 ~ 5mm, 2 ~ 3mm rau fillet vuam thiab lwm qhov chaw nrog kev tiv thaiv tsis zoo, thiab 5 ~ 6mm rau qhov sib sib zog nqus. Qhov deb ntawm lub nozzle mus rau kev ua haujlwm feem ntau tsis Ntau tshaj 5mm.
5. Txhawm rau txhawm rau tiv thaiv cov tsos ntawm vuam pores, yog tias muaj xeb thiab roj nyob ntawm qhov txuas nrog vuam, nws yuav tsum raug muab tu kom huv.
6. Rau kev vuam arc ntev, 2 ~ 4mm yog qhov zoo dua thaum vuam hlau zoo tib yam, thiab ~ 3 hli yog qhov zoo dua thaum vuam hlau stainless. Yog tias nws ntev heev, kev tiv thaiv tiv thaiv yuav tsis zoo.
7. Txhawm rau tiv thaiv lub nraub qaum sab hauv qab ntawm weld hlaws los ntawm oxidized, sab nraub qaum kuj yuav tsum muaj kev tiv thaiv los ntawm roj.
8. Txhawm rau tiv thaiv lub vuam pas nrog argon roj thiab pab txhawb lub sijhawm ua haujlwm vuam, qhov chaw nruab nrab ntawm tungsten j thiab cov haujlwm ntawm qhov chaw vuam feem ntau tswj lub kaum sab xis ntawm 80 ~ 85 °, thiab lub kaum sab xis nruab nrab ntawm cov muab tub lim thiab nplaim ntawm cov haujlwm workpiece yuav tsum me me li sai tau. Nws feem ntau kwv yees li 0 °.
9. Cua tsis zoo thiab cua. Nyob rau hauv cov chaw muaj cua, nco ntsoov ntsuas ntsuas los thaiv lub vas, thaum nyob sab hauv tsev yuav tsum ntsuas qhov cua kom tsim nyog.
