AWS A5.20 E70T-7Flux CoredArcWaya Wowotchererandi wodzitchinjiriza flux cored waya opangidwa kuti mkulu malowedwe kuwotcherera.Ndi yoyenera malo athyathyathya, opingasa komanso otsika pa DCEN polarity.Kuchita bwino kwambiri pakuwunika kwa X-ray, ndi desulfuration kumachepetsa kuwonongeka kwa mbale zowotcherera, zolumikizirana ndi chitsulo chapakatikati.Chodziwika
ntchito ndi zongopeka wamba ndi structural weldment komwe kuyika kwakukulu ndikulowa kwabwino komanso ine kapena kuthamanga kwachangu kumafunikira.Malo omwe alipo ndi weld yosalala, yopingasa yowotcherera ndi yoyimirira pansi ya weld ya fllet weld ndi lap joint.
