Muaj pes tsawg leeg: J507FeNi yog cov hlau tsis tshua muaj hlau vuam electrode uas muaj hlau (Fe) hmoov. Nws yog tsim tshwj xeeb rau vuam qis-alloy steels.
Txheej: Cov electrode yog coated nrog ib tug tsawg-hydrogen sodium txheej. Hom txheej no pab tiv thaiv cov hlau weld los ntawm kev sib kis thiab ua kom zoo weld zoo.
DCEP Connection Method: J507FeNi txais kev sib txuas ncaj qha tam sim no electrode zoo (DCEP) txoj kev. Qhov no txhais tau hais tias cov electrode txuas nrog lub davhlau ya nyob twg zoo ntawm lub zog hluav taws xob. DCEP feem ntau yog siv rau vuam daim ntaub ntawv nrog tsawg-carbon lossis low-alloy steel electrodes.
Vuam txoj hauj lwm: Cov electrode yog tsim los rau txhua txoj haujlwm vuam. Nws tuaj yeem siv rau hauv kab rov tav, ntsug, nyiaj siv ua haujlwm, thiab tiaj tus vuam txoj haujlwm, muab ntau yam hauv kev ua haujlwm vuam.
Kev Ua Haujlwm Zoo Tshaj Plaws: J507FeNi muaj kev vuam zoo heev, uas suav nrog cov yam ntxwv xws li arc ruaj khov, kev tswj xyuas zoo, thiab kev ua haujlwm yooj yim. Cov yam ntxwv no pab txhawb kom ua tiav cov welds zoo.
Zoo Low-Temperature Impact Toughness: Cov electrode pom zoo qhov kub thiab txias cuam tshuam toughness. Qhov no txhais tau hais tias qhov tshwm sim welds muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj nkig los yog muaj kev txo qis hauv lub zog. Cov khoom siv hluav taws xob ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau muaj qhov kub thiab txias tsis kam.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem vuam tshwj xeeb thiab cov txheej txheem yuav txawv nyob ntawm qhov kev thov tshwj xeeb, lub hauv paus hlau, thiab cov khoom siv vuam. Ua raws li cov chaw tsim khoom cov lus qhia thiab kev sab laj nrog cov kws tshaj lij vuam tuaj yeem pab xyuas kom pom cov txiaj ntsig zoo thaum siv J507FeNi.
Lub hom phiaj
Nws muaj feem xyuam rau cov vuam kub tsis tshua muaj steel siab hlab ntsha, xws li 16MnDR.

Cov kev ceev faj
1. Lub vuam electrode yuav tsum tau ci ntawm li 350 degree rau 1h ua ntej vuam, thiab nws yuav tsum tau preheated tsuas yog thaum siv.
2. Cov impurities xws li xeb, roj stain thiab noo noo yuav tsum tau tshem tawm ntawm qhov chaw ua haujlwm ua ntej vuam.
