AWS A5.1 E7028 Vuam Qwss

Lub tshuab hluav taws xob vuam AWS A5.1 E7028 yog lub electrode carbon steel uas muaj cov hydrogen-potassium-hlau-hmoov tsawg. Cov hmoov hlau hauv cov txheej txheej ua rau cov nqi tso tawm nce mus txog 180%. Nws muaj kev siv tau zoo heev uas ua rau nws muaj qhov ruaj khov, tsis muaj spatter, tshem tawm cov slag yooj yim thiab ua tiav txhua qhov chaw vuam. Cov hlau tso tawm muaj cov khoom siv kho tshuab zoo uas muaj kev tawv nqaij zoo heev thaum kub tsawg.

Daim Ntawv Thov

AWS A5.1 E7028 yog siv rau hauv kev vuam tiaj tiaj thiab tiaj tiaj hauv cov qauv ua los ntawm cov hlau carbon thiab cov hlau tsis tshua muaj hlau xws li 16Mn, 09Mn2Si thiab A, B, D, E steels siv hauv kev tsim nkoj.

Cov Lus Cim:

1. Lub electrode yuav tsum tau preheated ntawm qhov kub ntawm 350 ° C rau 1 teev. Preheat lub pas nrig thaum twg nws siv.

2. Cov khoom tsis huv xws li xeb, roj av thiab dej noo yuav tsum tau muab tshem tawm ntawm daim ntawv ua haujlwm.

3. Yuav tsum tau siv txoj hlua luv luv los vuam. Txoj kev vuam nqaim dua yog qhov zoo dua.

Kev khaws cia thiab ci ntawm E7028 Welding Electrode

Vim yog lub electrode hydrogen qis, E7016 xav tauci / ziabua ntej siv. Qhov kub uas pom zoo kom ziab lossis ci rau E7028 pas nrig raws li AWS A5.1, Rooj 1.3 yog 500-800°F (260-425°C) rau 1-2 teev.

Cov electrode uas ci los yog qhuav yuav tsum khaws cia rau hauv qhov cub uas nqa tau ntawm qhov kub ntawm 50-250°F (30-140°C) thaum siv. Cov electrode uas tsis siv yuav tsum muab xa rov qab mus rau qhov cub uas tuav ruaj ruaj.
