1. Siv cov khoom siv hluav taws xob nrog cov yam ntxwv ntsug sab nraud, thiab siv cov polarity zoo (cov vuam hlau txuas nrog cov electrode tsis zoo) thaum DC.
2. Nws yog feem ntau haum rau vuam stainless hlau ceev ntawm nyias daim hlau hauv qab 6 hli. Nws muaj cov yam ntxwv zoo nkauj vuam seam zoo thiab me me vuam deformation.
3. Cov roj tiv thaiv yog argon nrog purity ntawm 99.99 feem pua. Thaum lub vuam tam sim no yog 50-150A, argon roj ntws yog 8-10L / min, thiab thaum tam sim no yog 150-250A, argon roj ntws yog 12-15L / min.
4. Qhov ntev ntawm tungsten electrode protruding los ntawm cov roj nozzle yog nyiam dua 4-5mm. Nws yog 2-3 hli nyob rau hauv qhov chaw uas tsis zoo shielding xws li fillet vuam, thiab 5-6 hli nyob rau hauv qhov chaw nrog sib sib zog nqus grooves. Qhov kev ncua deb ntawm lub nozzle mus rau kev ua haujlwm feem ntau tsis txaus. ntau tshaj 15mm.
5. Txhawm rau tiv thaiv qhov tshwm sim ntawm vuam qhov pores, vuam qhov chaw yuav tsum tau ntxuav yog tias muaj xeb, roj paug, thiab lwm yam.
6. Qhov ntev ntawm qhov vuam arc yog qhov zoo dua 24mm thaum vuam zoo tib yam hlau, thiab 13mm thaum vuam stainless hlau. Yog tias nws ntev dhau lawm, cov nyhuv tiv thaiv yuav tsis zoo.
7. Txhawm rau ua kom cov hlau tsis xeb hlau argon roj zoo tiv thaiv lub vuam pas dej thiab ua kom yooj yim rau kev ua haujlwm vuam, cov kab nruab nrab ntawm cov tungsten electrode thiab cov khoom ua haujlwm ntawm qhov chaw vuam yuav tsum feem ntau tuav lub kaum sab xis ntawm 80-85 degree, thiab lub kaum sab xis ntawm cov xaim xaim thiab qhov chaw ntawm lub workpiece yuav tsum nyob ze li sai tau. Me me, feem ntau txog 10 degree.
8. Txhawm rau ua kom cov roj argon zoo tiv thaiv lub vuam pas dej thiab ua kom yooj yim rau kev ua haujlwm vuam, cov kab nruab nrab ntawm cov tungsten electrode thiab cov khoom ua haujlwm ntawm qhov chaw vuam yuav tsum feem ntau tuav lub kaum sab xis ntawm 80-85 degree, thiab lub kaum sab xis ntawm qhov chaw. muab tub lim thiab qhov chaw ntawm lub workpiece yuav tsum me me li sai tau. Feem ntau txog 10 degree.
9. Windproof thiab qhov cua. Nyob rau hauv qhov chaw muaj cua, nco ntsoov ntsuas kev thaiv lub vas, thiab ntsuas qhov cua kom tsim nyog hauv tsev.
