Inconel 690 ncaj weld nyob ntawm tej
Inconel 690 ncaj vuam hlau yog ib hom nickel-raws li alloy vuam khoom. Lawv yog tsim los rau vuam zoo xws li npib tsib xee-chromium alloys xws li Inconel 690 thiab 600 los yog cov hlau sib txawv. Lawv yog ua los ntawm npib tsib xee (tsawg kawg 58%), chromium (28-31%) thiab me ntsis hlau (7-11%). Lawv kuj muaj titanium, aluminium thiab lwm yam khoom kom lawv zoo dua. Lawv tuaj nyob rau hauv ncaj sticks. Txoj kab uas hla yog feem ntau ntawm 1.2mm thiab 4.0mm. Lawv zoo rau TIG thiab MIG vuam. Lawv muaj cov duab zoo thiab ruaj khov thaum siv.
Inconel 690 ncaj weld hlau yog siv nyob rau hauv nuclear fais fab nroj tsuag (steam generators, siab hlab ntsha), tshuaj kev lag luam (reactors, kav), zog (gas turbines, desulfurization khoom) thiab marine engineering (seawater desalination systems). Lawv tuaj yeem sawv qhov kub thiab txias thiab tiv thaiv corrosion. Qhov no ua kom cov vuam yog txhim khu kev qha nyob rau hauv huab mob. Lawv haum rau siab -xav tau kev lag luam.
Nta ntawm Inconel 690 ncaj weld nyob ntawm tej
