1. Basic Classification thiab Structure
ER308L yog cov khoom siv vuam hlau, cais raws li ER308L los ntawm AWS (American Society for Welding) cov qauv, suav nrog qeb A5.9 (cov khoom siv vuam hlau).
Cov khoom siv vuam hlau tsis muaj flux thiab yuav tsum tau siv nrog cov roj tiv thaiv (xws li CO₂ ntshiab lossis sib tov) thaum vuam. Nws yog feem ntau siv hauv MIG / TIG vuam txheej txheem.
2. Cov Qib sib xws ntawm Flux-Cored Wire
Yog xav tau flux-cored hlau, xaiv cov qauv xws li E308LT-1, E308LT0-1, thiab E308LT1-1. Cov no ua raws li AWS A5.22 (Fluid-Cored Wire) tus qauv.
Fluid-cored hlau yog ntim nrog flux, uas ua rau muaj kev tiv thaiv huab cua thaum vuam. Qee tus qauv txawm ua tiav nws tus kheej- thaiv kev tiv thaiv (tsis muaj roj sab nraud yuav tsum tau ua).
3. Qhov txawv tseem ceeb
| yam khoom | ER308L (Tshuaj Vuam Hlau) | E308LT-1 (Cov kua dej-cored vuam hlau) |
|---|---|---|
| qauv | Khoom, tsis muaj internal flux | Tubular zoo, muaj flux |
| Txoj kev tiv thaiv | Yuav tsum muaj cov roj tiv thaiv sab nraud. | Tus kheej-kev tiv thaiv tuaj yeem ua tiav los ntawm flux lossis los ntawm kev siv co- roj uas twb muaj lawm. |
| AWS Standard | A5.9 (cov khoom siv vuam hlau) | A5.22 (Cov kua -cored vuam hlau) |
| Hom kev siv | MIG/TIG welded stainless hlau | Gas shielded welding thiab tag nrho - txoj haujlwm vuam yog tsim rau ntawm - qhov chaw tsim kho. |
4. Cov lus pom zoo siv
Yog tias koj xav tau cov khoom siv vuam hlau, xaiv ER308L ncaj qha;
Yog tias koj xav tau flux-cored vuam hlau, xaiv cov qauv xws li E308LT-1, E308LT0-1, lossis E308LT1-1, thiab paub meej tias nws txoj kev tiv thaiv (gas shielded lossis self-shielded).
