Welding yog dab tsi? Koj puas paub? Vuam tau raug hu ua, "qhov zoo tshaj plaws khaws cia zais cia" hauv kev npaj ua haujlwm. Vuam yog dav siv hauv kev tsim kho, kev tsim khoom, thiab ntau lwm yam lag luam, ua rau nws yog ib qho kev txawj ntse uas yuav tsum tau nyob rau hauv ib txwm muaj. Txij thaum pib ntawm kev vam meej, peb tau tso siab rau cov txuj ci ntawm cov welders los txhawb peb lub neej.
Keeb kwm ntawm Vuam
Cov duab ntawm cov welders thaum ub thiab cov cuab yeej muaj nyob rau hauv lub qhov ntxa uas tau kaw ntev hauv Egypt. Thawj Tswj Hwm Roosevelt, nyob rau hauv tsab ntawv mus rau Thawj Kav Tebchaws Winston Churchill, khav txog qhov kev tshawb pom ntawm cov txheej txheem vuam tshiab uas ua rau Asmeskas tsim cov nkoj nrog qhov nrawm tsis sib npaug hauv keeb kwm ntawm kev tsim nkoj. Saib seb qhov kev tshawb pom thiab kev txhim kho hauv cov txheej txheem vuam thiab metallurgy tau ua rau cov thev naus laus zis zoo kawg nkaus uas hloov lub ntiaj teb peb nyob niaj hnub no.
Welding yog dab tsi, Xijpeem?
• Vuam yog kev sib koom ua ke ntawm ob lossis ntau dua cov ntaub ntawv los ntawm cov cua sov lossis cua sov thiab lub siab, ua kom muaj kev sib txuas ntawm ob daim hlau.
• Hlau melts ntawm 2,800 degrees Fahrenheit.
• Ib daim ntawv nrov ntawm vuam, Gas Metal Arc Vuam (GMAW), siv cov khoom siv hluav taws xob siv hluav taws xob. GMAW muaj ntau yam hauv kev tsim khoom thiab kev tsim kho siab. Vuam ib tug ncej rau ib tug chopper yuav xav tau no MIG vuam.
• Gas Tungsten Arc Vuam (GTAW) siv cov tungsten electrode uas tsis siv tau los ua cov welds siab. GTAW muaj nyob rau hauv aerospace, nuclear, thiab zaub mov kev lag luam. Nws tseem hu ua TIG welding, (melting ua ke siab alloy nyias cov ntaub ntawv, xws li stainless hlau thiab titanium) tso me ntsis cua sov rau hauv cov khoom ua rau tsawg distortion.
• Shielded Hlau Arc Vuam (SMAW) siv flux-them electrodes. Feem ntau hu ua "stick" lossis "stick-electrode" vuam, SMAW yog ib qho kev xaiv ntau zaus rau kev kho thiab qee zaus vuam.
• Tseem muaj lwm txoj kev vuam, Tsis Siv Neeg Vuam, siv hluav taws xob tsis kam thiab siab rau fuse hlau, es tsis yog arc.
