Cov qauv hlau yog hais txog cov qauv tsim los ntawm cov khoom siv hlau, uas yog ib qho ntawm cov qauv tseem ceeb ntawm lub tsev. Cov qauv yog tsuas yog tsim los ntawm cov kab hlau, steel kem, steel trusses thiab lwm yam khoom ua los ntawm seem steel thiab steel phaj. Cov khoom lossis cov khoom feem ntau txuas nrog welds, bolts lossis rivets. Vim nws lub teeb yuag thiab kev tsim kho yooj yim, nws tau siv dav hauv cov tuam tsev loj, cov chaw, cov tsev tshwj xeeb siab thiab lwm qhov chaw.
Hauv cov txheej txheem vuam ntawm cov qauv steel, muaj ntau yam teeb meem uas yuav tsum tau them sai sai rau. Yog tias koj tsis saib xyuas lawv, koj yuav ua yuam kev loj. Cov hauv qab no yog qee yam uas yuav tsum tau saib xyuas:
1. Kev xaiv tsis raug voltage thaum vuam
Thaum lub sij hawm vuam, tib qhov hluav taws xob arc yuav tsum raug xaiv tsis hais txog kev thim rov qab, txhaws, npog thiab zawj loj. Nyob rau hauv txoj kev no, qhov yuav tsum tau nkag mus rau qhov tob thiab dav yuav tsis ncav cuag, thiab qhov tsis xws luag xws li undercut, cua qhov thiab txaws yuav tshwm sim.
Kev daws: Feem ntau, qhov sib thooj ntev arc lossis luv arc yuav tsum raug xaiv raws li cov xwm txheej sib txawv kom tau txais vuam zoo dua thiab ua haujlwm tau zoo. Piv txwv li, txhawm rau kom tau txais kev nkag siab zoo dua thaum lub sij hawm rov qab vuam, kev ua haujlwm luv luv yuav tsum tau saws, thiab thiaj li kom tau txais kev ua haujlwm siab dua thiab qhov dav nkag mus rau lub sijhawm txhaws vuam lossis capping vuam, arc voltage tuaj yeem tsim nyog nce.
2. Weld deformation tsis tswj kom zoo
Thaum lub sij hawm vuam, qhov deformation tsis raug tswj los ntawm cov yam ntxwv ntawm vuam ib ntus, kev npaj cov neeg ua haujlwm, groove daim ntawv, welding specification xaiv thiab cov txheej txheem kev ua haujlwm, ua rau loj deformation tom qab vuam, nyuaj kho thiab nce nqi, tshwj xeeb tshaj yog rau cov phaj tuab thiab loj workpieces, uas. yog qhov nyuaj los kho thiab yooj yim ua rau tawg los yog lamellar kua muag los ntawm kev kho kho tshuab.
Kev daws: txais yuav tsim nyog vuam ib ntus, xaiv qhov tsim nyog vuam specifications thiab kev khiav hauj lwm txoj kev, thiab txais yuav los tiv thaiv deformation thiab nruj fixation ntsuas.
3. Vuam tsis tswj vuam tam sim no
Thaum lub sij hawm welding, txhawm rau ua kom qhov kev nce qib, lub pob tw welds ntawm nruab nrab thiab tuab daim hlau yuav tsum tsis txhob beveled. Lub zog Performance index txo qis, txawm tias ua tsis tau raws li tus qauv yuav tsum tau ua, thiab cov kab nrib pleb tshwm sim thaum lub sij hawm khoov, uas yuav ua rau qhov kev ua tau zoo ntawm kev sib koom tes vuam tsis tuaj yeem lav, thiab ua rau muaj kev phom sij rau kev nyab xeeb ntawm cov qauv.
Kev daws: Lub vuam tam sim no yuav tsum tau tswj raws li qhov vuam tam sim no hauv cov txheej txheem tsim nyog, thiab 10 ~ 15 feem pua loj raug tso cai. Lub blunt ntug loj ntawm qhov zawj yuav tsum tsis pub tshaj 6 hli. Thaum lub taub qab vuam, thaum lub phaj thickness tshaj 6 hli, qhov zawj yuav tsum tau txiav rau vuam.
