Kev txiav txim siab vuam
DX51D Z275 steel tuaj yeem welded siv cov txheej txheem vuam, tab sis qee qhov kev ceev faj yog tsim nyog vim yog zinc txheej:
Arc Vuam: Zinc vaporizes thaum vuam, ua pa taws. Yuav tsum muaj qhov cua thiab cov cuab yeej tiv thaiv zoo.
Spot Welding / Resistance Vuam: Cov txheej zinc tuaj yeem txo cov hluav taws xob conductivity; kho electrode siab thiab vuam tsis raws li.
Cov Txheej Txheem Tshwj Xeeb: Rau cov txheej txheej zinc thicker lossis cov ntawv thov tseem ceeb, kev tshem tawm cov txheej hauv zos los yog siv cov txheej txheem vuam zoo ua kom zoo dua.
kev sib koom ua ke zoo thiab txo cov porosity.
Vim li cas DX51D Z275 nyiam dua
High corrosion kuj nrog lub neej ua haujlwm ntev
Formability zoo heev rau kev sib sib zog nqus nqus thiab khoov
