1. Cov khoom sib txawv
- ER308L yog stainless hlau TIG vuam hlau, belongs rau cov roj-shielded vuam hlau qeb.
- 308L feem ntau yog hais txog stainless hlau vuam electrodes (xws li E308L-16), teej tug mus rau phau ntawv arc vuam electrodes.
2. Qhov sib txawv ntawm cov yam ntxwv ntawm daim ntawv thov
ER308L vuam hlau muaj ultra- cov ntsiab lus carbon tsawg, kev ua haujlwm vuam zoo, ruaj khov arc, tsis muaj spatter, thiab zoo nkauj weld tsim. Nws yog haum rau tag nrho cov - txoj hauj lwm welding thiab muaj zoo tawg kuj. Nws yog tsuas yog siv rau vuam 304L thiab 308L stainless hlau cov ntaub ntawv, thiab cov kev siv xws li petrochemicals, siab hlab ntsha, khoom noj khoom haus thiab kev kho mob, engineering machinery, thiab nuclear zog.
308L vuam electrodes kuj muaj ultra- cov yam ntxwv qis, tuaj yeem siv nrog AC thiab DC, haum rau txhua qhov - txoj haujlwm vuam, muaj cov txheej txheem vuam zoo heev, zoo nkauj vuam tsim, thiab ua haujlwm zoo rau metallographic corrosion. Lawv tsuas yog siv rau vuam 304 thiab 308 stainless hlau, thiab tsim nyog rau vuam CR90 thiab C28N11Ti stainless hlau qauv.
3. Cov kev siv sib txawv
Thaum siv ER308L, yuav tsum muaj kev tiv thaiv roj argon ntshiab, qhov tam sim no yuav tsum nyob nruab nrab ntawm 100-200A, cov hlau txuas ntev yuav tsum yog 3-5 hli, thiab nws raug nquahu kom muab cov roj argon tiv thaiv rau sab nraum qab ntawm qhov chaw vuam.
Thaum siv 308L vuam electrodes, preheating ntawm 320-350 degrees Celsius rau ib teev yog yuav tsum tau. Nws raug nquahu kom siv DC fais fab mov, tswj cov khoom siv tam sim no thiab cov cua sov, thiab ua kom qhov kub thiab txias hauv qab 150 degrees Celsius.
