ER70S6 yog cov hlau me me uas muaj cov manganese thiab silicon ntau dua li lwm cov qauv ntawm MIG hlau rau cov khoom zoo welds thaum siv cov khoom qias neeg, oily, los yog xeb hlau.Cov ntsiab lus ntawm silicon siab ua kom lub cev muaj zog ntawm lub pas dej ua ke, yog li tsim cov hlaws zoo nkauj thiab ua rau tsawg kawg tom qab vuam sib tsoo.Cov hlau no yog tsim los muab cov porosity-dawb, x-ray zoo welds ntawm lub siab tshaj plaws tensile lub zog (raws li welded) ntawm tag nrho cov dawb carbon hlau nyob ntawm tej.
Daim ntawv thov: dav siv hauv khw nrog cov khoom siv tsis zoo los yog xeb, oily daim hlau;steel castings los yog forging khaws cia;tej yaam num hauv tsev;ntawv hlau;tso tsheb hlau luam;kev tsim kho
