Txheej txheem tsis: nruj me ntsis tswj cov cua sov input kom tsis txhob coarse nplej los yog tsim ntawm brittle theem;
Cov khoom siv vuam sib txuam: Xaiv cov vuam hlau uas muaj homogeneous rau lub hauv paus hlau lossis muaj cov ntsiab lus tshem tawm tsawg, xws li ERTi-5, ERTi-7, thiab lwm yam.
Tshaj tawm -weld heat treatment and testing
Kev ntxhov siab nyem annealing: feem ntau ua ntawm 500-600℃kom txo qis kev ntxhov siab;
Kev kho kev laus: haum rau lossis + titanium alloys los txhim kho lub zog thiab tawv;
Tsis yog-kev kuaj kev puas tsuaj: 100% kev kuaj hluav taws xob (RT) lossis kuaj ultrasonic (UT), ntxiv los ntawm kev ntsuas kev nkag siab (PT) kom ntseeg tau tias cov vuam tsis muaj qhov tsis xws luag.
Stamping molding: qhov tseeb qhov tseeb thiab kev tswj xyuas qhov zoo
Vaj huam sib luag weld kho
Residual qhov siab tswj: qhov seem qhov siab ntawm qhov vuam yuav tsum tau smoothed kom yaug nrog lub hauv paus hlau kom tsis txhob muaj kev ntxhov siab thiab txaus ntshai thaum lub sij hawm stamping;
