Nyob rau hauv lub ntiaj teb vuam, kev xaiv ntawm xaim yog qhov tseem ceeb raws li nws cuam tshuam ncaj qha cuam tshuam qhov zoo thiab lub zog ntawm weld. Muaj ntau cov hlau feem ntau siv nyob rau hauv cov txheej txheem vuam, txhua tus nrog nws tus kheej cov yam ntxwv tshwj xeeb thiab kev siv.
Ib qho ntawm cov hom pom zoo tshaj plaws yog cov hlau ruaj khov, feem ntau siv hauv roj av hlau arc vuam (GMAW), tseem muaj roj (hlau inert roj) vuam. Cov xov hlau cov khoom lag luam feem ntau ua los ntawm ib qho hlau lossis cov hlau, xws li hlau, stainless hlau, txhuas, lossis tooj. Piv txwv li, cov xov hlau me me nyiam er70s- 6}}} - aliecs. Lawv muab Weldability zoo thiab paub txog kev tsim cov tshuaj huv thiab muaj zog nrog cov khoom siv tsis muaj zog. Stainless hlau khoom siv xov hlau, xws li ER308 rau vuam {}}}}} paab cov khoom ntawm cov hlau.
Lwm qib tseem ceeb yog flux - Cored hlau, uas yog siv hauv flux- cored arc vuam (FCaw). Flux - Cov xov hlau muaj muaj cov hlau riam uas muaj cov tshuaj sib xyaw ua ke. Qhov no flux muaj ntau yam khoom xyaw zoo li deoxidizers, cov neeg sawv cev tsis zoo, thiab cov khoom siv alloy. Muaj ob lub ntsiab nyob rau - hom: roj {{{{} We} {{8} shielded. Roj - shielded flux -, feem ntau yog kev sib xyaw ntawm Weld pas dej ua ke los ntawm cov kev sib kis weld los ntawm cov pa weld Lawv feem ntau siv nyob rau hauv cov txheej txheem steel vuam, muab cov nqi depepition ntau thiab Weld zoo. Tus kheej - shielded flux - cored tiv thaiv roj, tsis xav tau flux tsim nws tus kheej tiv thaiv cua thaum vuam. Qhov no ua rau lawv yooj yim rau sab nraum zoov lossis nyuaj - rau {{20 20}} nkag mus rau thaj chaw vuam.
Tungsten inert roj (tsov) vuam kuj muaj nws cov xov hlau tshwj xeeb. Tig cov xov hlau feem ntau yog ua los ntawm cov khoom tib yam li cov hlau hauv lub hauv paus tau welded. Piv txwv li, thaum vuam aluminium, lub txhuas tig hlau hlau yuav raug siv. Cov hlau no tau siv los ua cov tub lim dej, thiab txij li Tig Vuam siv cov roj ntsha (Argone
Nyob rau hauv submerged arc vuam (pom), cov xov hlau siv yog feem ntau hlau, qis {{{{{{}} love hlau, lossis stainless hlau, nyob ntawm daim ntawv thov. Cov xaim, nrog ib txheej ntawm glux glux, ua cov ntaub thaiv tiv thaiv uas pab ua kom muaj siab- zoo welds nrog tob nkag. Pom cov xov hlau tau muab pub rau hauv weld cheeb tsam, ua rau nws muaj zog {}} pipe} Cov khoom lag luam thiab cov raj xa khoom.
Thaum xaiv lub vuam hlau, yam xws li cov hom hlau, cov vuam cov khoom siv ntawm Weld, thiab cov txheej txheem vuam ntawm cov vuam qhov chaw xav tau kev xav tau. Piv txwv li, nyob rau hauv lub siab - av noo lossis sab nraum zoov ua haujlwm ntawm cov hlau tsis muaj zog, thaum lub sij hawm zoo nkauj ntawm cov hlau uas tsim nyog yuav yog nyiam.
In conclusion, the variety of welding wires available allows welders to select the most suitable option for their specific projects, ensuring strong, durable, and high - quality welds.
