Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum siv argon arc vuam:
1. Cov khoom siv hluav taws xob nrog cov yam ntxwv ntsug sab nraud yog saws, thiab qhov zoo polarity yog saws nyob rau hauv DC (lub vuam hlau txuas nrog rau tus ncej tsis zoo).
2. Nws yog feem ntau haum rau vuam ntawm nyias daim hlau hauv qab 6 hli, nrog rau cov yam ntxwv ntawm zoo nkauj weld tsim thiab me me vuam deformation.
3. Lub shielding roj yog argon nrog purity ≥ 99.95%.Thaum lub vuam tam sim no yog 50 ~ 150A, argon ntws yog 6 ~ 10L / min, thiab thaum lub sijhawm tam sim no yog 150 ~ 250A, argon ntws yog 12 ~ 15L / min.Tag nrho cov siab nyob rau hauv lub raj mis yuav tsum tsis txhob qis dua 0.5MPa kom paub meej lub purity ntawm argon filling.
4. Qhov ntev ntawm tungsten electrode protruding los ntawm cov roj nozzle yog qhov zoo dua 4 ~ 5mm, 2 ~ 3mm nyob rau hauv qhov chaw uas tsis zoo shielding xws li fillet welding, 5 ~ 6mm nyob rau hauv qhov chaw nrog qhov sib sib zog nqus zawj, thiab qhov deb ntawm lub nozzle mus rau qhov chaw ua hauj lwm yog. feem ntau tsis ntau tshaj 15mm.
5. Txhawm rau tiv thaiv qhov tshwm sim ntawm vuam qhov pores, cov roj stain, nplai thiab xeb ntawm cov phab ntsa sab hauv thiab sab nrauv ntawm qhov vuam yuav tsum tau ntxuav.
6. Lub arc ntev ntawm stainless hlau vuam yog 1 ~ 3mm, thiab cov nyhuv tiv thaiv tsis zoo yog tias nws ntev dhau lawm.
7. Thaum lub pob tw rov qab, txhawm rau tiv thaiv lub nraub qaum ntawm lub hauv paus weld hlaws los ntawm oxidized, lub nraub qaum kuj yuav tsum tau tiv thaiv cov roj.
8. Txhawm rau tiv thaiv lub vuam pas dej kom zoo nrog argon thiab ua kom yooj yim rau kev ua haujlwm vuam, lub kaum sab xis ntawm cov kab nruab nrab ntawm tungsten electrode thiab cov khoom ua haujlwm ntawm vuam txoj hauj lwm yuav tsum tau khaws cia feem ntau ntawm 75 ~ 85 °, thiab lub kaum sab xis ntawm cov muab tub lim. hlau thiab workpiece nto yuav tsum me me li sai tau, feem ntau tsawg dua 10 ° ntawm phab ntsa thickness thiab tsis ntau tshaj 1 hli.Txhawm rau kom ntseeg tau qhov nruj ntawm qhov vuam, ua tib zoo saib xyuas qhov zoo fusion zoo ntawm kev sib koom ua ke, thiab sau lub pas dej molten thaum lub sij hawm arc nres.
