AWS A5.20 E70T-7 Flux Cored Arc Vuam Electrodes Flux Core Vuam Hlau

EN ISO 17632-AT 42 ZW N 3

Cov yam ntxwv thiab daim ntawv thov
AWS A5.20 E70T-7Flux CoredArcHlau vuamyog ib txoj hlau flux cored uas tiv thaiv tus kheej tsim los rau kev vuam nkag mus rau hauv siab. Nws tsim nyog rau qhov chaw tiaj tus, kab rov tav thiab nqes hav ntawm DCEN polarity. Kev ua tau zoo heev ntawm kev tshuaj xyuas X-ray, thiab desulfuration txo qhov tawg hauv kev vuam cov phaj tuab, cov pob qij txha thiab cov hlau carbon nruab nrab. Qhov ib txwm muaj
Cov ntawv thov yog kev tsim khoom dav dav thiab kev vuam cov qauv uas muaj kev tso dej siab nrog kev nkag mus zoo thiab I lossis kev mus ncig ceev ceev. Cov chaw muaj yog kev vuam tiaj tus, kev vuam kab rov tav thiab cov ntsug nqes ntawm kev vuam rau fllet weld thiab lap joint.

Cov Tshuaj Sib Xyaws Ib Txwm Muaj ntawm Cov Hlau Weld (%)

Cov lus qhia txog kev siv:
1. DC(-) polarity yog pom zoo.
2. thaum qhov cuam tshuam ntawm cov hlau vuam yog qhov tseem ceeb.
3. Khaws cov khoom kom qhuav, thaum nws khaws cia lossis xa tuaj.
