Tam sim no, kev tsim thiab kev siv ntawm CO2 gas-shielded vuam hlau yog vam meej, nrog rau qee lub teb chaws tsim xws li peb li accounting rau 40-50% ntawm tag nrho cov vuam consumables.Nws tau txais koob meej los ntawm hnub hauv ntau lub tuam tsev, maj mam hloov phau ntawv arc vuam.Ib qho ntawm nws cov txiaj ntsig tseem ceeb yog nws cov nqi vuam qis, ua rau nws pheej yig dua li lwm cov txheej txheem vuam.

Gas-shielded vuam hlau kuj boasts ntawm high efficiency efficiency thiab tsawg zog noj, ua rau nws zoo meej rau high-volume vuam tej yaam num.Nws kuj yog ib qho yooj yim heev rau kev khiav lag luam, raws li nws tso cai rau vuam nyob rau hauv txhua txoj hauj lwm, nrog rau cov nyiaj siv ua haujlwm vuam.Qhov no ua rau nws yooj yim rau vuam nyob rau hauv qhov chaw nruj los yog cov ces kaum nyuaj.

Tsis tas li ntawd, welds nrog CO2 gas-shielded vuam hlau muaj qhov tshwj xeeb zoo.Nrog rau cov ntsiab lus tsis tshua muaj hydrogen thiab cov ntsiab lus nitrogen tsawg, cov welds muaj kev ua haujlwm zoo heev.Welds kuj muaj tsawg deformations tom qab ua tiav, ua kom nws zoo meej rau txawm tias qhov kev sib txuas zoo tshaj plaws.Cov hlau kuj muaj ntau yam raws li nws tsim nyog rau vuam nyias, nruab nrab, thiab tuab daim hlau.

Hauv kev xaus, peb cov Gas-Shielded Solid Vuam Hlau yog ib qho tseem ceeb ntxiv rau koj cov txheej txheem vuam, thiab nws cov txiaj ntsig ntau ua rau nws tsis zoo los ntawm lwm cov txheej txheem vuam.Nrog rau qhov zoo tshaj plaws, tus nqi qis, kev ua haujlwm siab, thiab kev siv yooj yim, nws tau nrawm dhau los ua cov txheej txheem vuam nyiam hauv ntau qhov chaw.Xaiv qhov zoo tshaj plaws, thiab tau txais txiaj ntsig zoo nrog peb Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob.
