Q1: Dab tsi sab hauv tsis zoo yog qhov tseem ceeb hauv cov kav dej welds?
A:Cov teeb meem tseem ceeb sab hauv suav nrogpores, slag suav nrog, tawg, thiabtsis muaj fusion. Cov teeb meem no, tshwj xeeb tshaj yog cov kab nrib pleb thiab tsis muaj fusion, tuaj yeem ua cov ntsiab lus pib rau kev puas tsuaj hauv kev ntxhov siab-6-7.
Q2: Dab tsi ua rau tsis muaj kev sib xyaw ua ke hauv cov raj xa dej girth welds?
A:Tsis muaj fusion, tshwj xeeb tshaj yog nyob rau hauv paus, feem ntau yog tshwm sim los ntawm cov txheej txheem vuam tsis zoo, tsis muaj, los yog muaj cov kab mob. Kev soj ntsuam ntawm cov xwm txheej tsis ua haujlwm qhia tau hais tias ntau qhov xwm txheej muaj cov ntaub ntawv kho lossis raug pib ncaj qha los ntawm qhov tsis muaj fusion ntawm lub hauv paus-6.
Q3: misalignment (hi-lo) cuam tshuam li cas weld zoo?
A:Misalignment tsim geometric discontinuities ua raukev nyuaj siab concentrationthiab strain intensification nyob rau hauv load. Nws yog ib qho tseem ceeb, nrog rau cov phab ntsa tsis sib npaug, ua rau girth weld tsis ua haujlwm-6.
Q4: Dab tsi yog cov txheej txheem vuam siv rau kab yeeb nkab?
A:Cov txheej txheem muaj xws li:
Shielded Hlau Arc Vuam (SMAW):Cov cuab yeej siv yooj yim, hloov tau yooj yim, tab sis qis dua thiab kev ruaj ntseg zoo-5.
Gas Metal Arc Vuam (GMAW):Xws li CO2 vuam thiab MIG / MAG vuam. Muab cov khoom zoo thiab kev ua haujlwm zoo, haum rau stainless hlau thiab txhuas alloys-5.
Gas vuam:Siv cov nplaim taws los ntawm cov pa roj (xws li acetylene, propane). Cov cuab yeej siv yooj yim, tus nqi qis, siv rau qis- melting- taw tes hlau-5.
Laser vuam:Siab zog, precision, thiab ceev, feem ntau automated-5.
Ultrasonic vuam:Siv cov tshuab kev co thiab kev sib txhuam kub, haum rau cov hlau thiab tsis yog -hlau-5.
Q5: Dab tsi yuav tsum tau xav txog ua ntej pib txheej txheem vuam?
A:Nws yog ib qho tseem ceeb los ntxuav cov yeeb nkab bevel, sab hauv / sab nrauv phab ntsa, thiab cov chaw nyob ib sab ntawm cov kab mob xws li roj, xeb, thiab nplai. Xaiv qhov raug electrodes, xov hlau, thiab vuam tsis raws li cov yeeb nkab khoom thiab specifications kuj tseem ceeb heev-5
