Gas tungsten arc vuam (GTAW) siv cov khoom siv tsis siv tungsten electrode uas yuav tsum tau tiv thaiv nrog cov roj inert Lub arc yog tsim los ntawm qhov kawg ntawm cov electrode thiab ua haujlwm kom yaj lub hlau raug welded. Lub consumable muab tub lim yog ntxiv manually los yog ib co txheej txheem mechanized.
Cov roj siv li cas thaum cov roj tungsten arc vuam?
GTAW, tseem hu ua tungsten inert gas (TIG) vuam, yog ib hom arc vuam uas tsim cov vuam siv cov khoom siv tsis siv tungsten electrode. Inert gases xws li argon lossis heliumyog siv los tiv thaiv thaj chaw raug welded los ntawm kev sib kis thiab feem ntau, txawm tias tsis yog tag nrho, kev siv vuam yuav xav tau cov hlau muab tub lim.
Qhov polarity yog siv rau hauv cov roj tungsten arc vuam?
Negative polarity yog pom zoo rau GTAW (TIG vuam) vim qhov no tiv thaiv cov tungsten electrode los ntawm overheating.
Cov ntsiab lus ntawm cov roj tungsten arc vuam yog dab tsi?
Txoj Cai Ua Haujlwm ntawm TIG Vuam
Nyob rau hauv TIG Vuam txheej txheem, ib qho arc yog tsim nyob rau hauv nruab nrab ntawm cov khoom siv tsis siv tungsten electrode thiab workpiece uas yuav tsum tau koom nrog. Lub arc thiaj li tsim tawm tsim kom muaj cua sov uas ua rau ob daim hlau melts thiab fuses lawv ua ke los ua ib qho kev sib txuas uas muaj zog los ntawm kev siv cov hlau muab tub lim
Qhov kub ntawm cov roj tungsten arc vuam yog dab tsi?
Gas tungsten arc welding (GTAW)
Weld pas dej kub tuaj yeem ncav cuag 2500 °C (4530 ° F). Ib qho roj inert txhawb nqa lub arc thiab tiv thaiv cov hlau molten los ntawm atmospheric paug. Cov roj inert feem ntau yog argon, helium, lossis sib xyaw ntawm helium thiab argon.
