Kev txiav txim siab tshwj xeeb rau Vuam 6061-T6 Aluminium
Vuam6061-T6 txhuasxav tau precision thiab kev txawj ntse. NtawmGNEE, peb ua TIG (Tungsten Inert Gas) thiab MIG (Metal Inert Gas) welding siv cov neeg ua haujlwm txawj ntse kom ntseeg tau siab - cov pob qij txha zoo.
Aluminium ib txwm tsim ib txheej oxide nyias ntawm nws qhov chaw, uas melts ntawm qhov kub siab tshaj qhov txhuas nws tus kheej. Txhawm rau ua kom muaj zog thiab txhim khu kev qha welds, qhov saum npoo yuav tsum yogpreheated rau kwv yees li 350℃F (176 degree). Preheating tshem tawm cov oxide thiab txo qhov kev pheej hmoo ntawm kev qaug zog los yog ntiav welds. Yog tsis muaj cov kauj ruam no, cov welded sib koom yuav raug cuam tshuam, cuam tshuam rau tag nrho lub zog thiab durability ntawm cov khoom.
