Dab tsi tsis ua thaum vuam?

Vuam yog lub siab - kev ua haujlwm pheej hmoo uas yuav tsum ua raws li kev nyab xeeb ntawm kev tswj hwm nrog kev nyab xeeb. Txawm tias ib qho kev ua txhaum me me thaum lub sijhawm ua tau ua rau muaj cov xwm txheej xws li hluav taws, hluav taws xob, lossis tsis zoo weld zoo. Txhawm rau kom muaj kev nyab xeeb ntawm welders thiab kev ntseeg tau ntawm vuam cov txiaj ntsig, nws yog qhov tseem ceeb kom nkag siab txog kev ua dab tsi yuav tsum zam. Cov npe txuas ntxiv no taboos thaum lub sijhawm vuam.
1. Tsis txhob quav ntsej cov khoom tiv thaiv tus kheej
Cov cuab yeej tiv thaiv tus kheej (PPE) yog kab kawg ntawm kev tiv thaiv rau cov neeg tiv thaiv kev phom sij, thiab kev tsis saib xyuas nws yuav ua rau raug mob hnyav.
Tsis txhob weld tsis hnav lub kaus mom hlau. Lub arc tsim tawm thaum lub sij hawm vuam emits muaj hluav taws xob hluav taws xob muaj zog thiab muaj qhov muag pom "yog tias nws ncaj qha rau lub qhov muag. Thaum muaj mob hnyav, nws kuj yuav ua rau tsis pom kev. Ib qho ntxiv, cov txim taws thiab txhais los ntawm vuam vuam tuaj yeem txaws rau lub ntsej muag, ua rau kub hnyiab. Qee cov neeg tua tsiaj yuav xav tias "luv {{{{- lub tswv yim vuam tsis ua li cas," tab sis lub tswv yim no yog ob peb feeb ntawm arc hluav taws xob tuaj yeem ua rau lub qhov muag puas.
Tsis txhob hnav khaub ncaws tsis tsim nyog. Khoom cua fiber ntau (xws li polyester thiab nylon) yuav tsum tsis txhob hnav kom sai thaum muaj qhov kub thiab txias, ua rau tawv nqaij thiab ua rau muaj kev kub hnyiab heev. {- fitting khaub ncaws lossis khaub ncaws nrog cov ris thiab hems uas tsis tau txwv, raws li cov txim tau yooj yim nkag mus rau lawv thiab zes cov ntaub. Ib yam li ntawd, hnab looj tes uas hnav tawm, muaj qhov, lossis tsis yog nplaim- retardant yuav tsum tsis txhob siv. Yog tias tsis muaj kev tiv thaiv zoo, txhais tes muaj kev cuam tshuam los hlawv los ntawm high- kub ua haujlwm lossis hluav taws xob los ntawm kev sib cuag nrog cov chaw nyob.
Zam kev tiv thaiv ko taw. Vuam cov chaw feem ntau muaj cov khoom hnyav xws li hlau workpieces thiab khoom siv. Hnav cov khau dog dig es tsis txhob siv hlau - Cov khau khau kom muaj kev nyab xeeb yuav ua rau raug mob ko taw yog khoom poob. Moreover, the ground may be slippery due to oil stains or water, and non-slip safety shoes can prevent slips and falls.​
2. Tsis txhob ua haujlwm nrog cov khoom siv tsis raug cai
Siv cov khoom siv puas los yog ua haujlwm vuam yog qhov kev txaus siab zais cia uas tuaj yeem ua rau hluav taws xob, khoom puas tsuaj, lossis hluav taws kub.
Tsis txhob siv lub tshuab vuam nrog lub zog muaj hluav taws xob puas. Lub zog tawg lossis raug hluav taws xob raug thaiv cov txheej txheej yuav ua rau muaj kev sib cuag tib neeg thiab cov hlau nyob, ua rau hluav taws xob nyob hauv. Ib yam li ntawd, rub tawm plugs lossis cov thom khwm nrog kev sib cuag tsis zoo tuaj yeem ua rau muaj cua sov tsis zoo, ua kom muaj kev pheej hmoo hluav taws. Qee tus neeg ua haujlwm yuav qhwv qhov chaw tsis zoo nrog cov kab xev ib ntus, tab sis qhov no tsuas yog hloov chaw tsim nyog lossis hloov chaw tsim nyog lossis hloov kho kom tsim nyog lossis hloov kho kom tsim nyog lossis hloov kho kom zoo rau hauv siab, ua nws cov nyhuv tiv thaiv.
Tsis txhob quav ntsej cov teeb meem nrog lub teeb cuj lossis cable. Ib qho thaiv cov vuam hluav taws xob ncau yuav cuam tshuam cov roj ntws (rau roj av {{1} {qhov tsis txaus ntseeg, ua rau weld tsis raug xws li pores. Ib lub xoob sib cuag yuav ua rau muaj kev tiv thaiv ntau dhau thiab cua sov, txawm tias hlawv lub teeb. Vuam cab Tsis tsuas yog lawv pheej hmoo hluav taws xob, tab sis kev tiv thaiv hluav taws xob ntxiv kuj tseem tuaj yeem ua rau lub cable rau overheat, muaj peev xwm burniting cov khoom nyob ze cov khoom siv.
Zam tsis txhob siv cov roj thooj voos kheej uas tsis muaj txog ntawm tus qauv. Cov thooj voos kheej (xws li Argon, carbon dioxide, los yog acetylene shooj dej) nrog kev kuaj xyuas tas sij hawm, xeb, lossis puas yog qhov txaus ntshai heev. Siv cov thooj voos kheej no yuav ua rau muaj roj av xau {2} pa roj cua zoo li cov nplaim taws zoo li cov nplaim taws zoo li cov nplaim taws zoo li ARGON tuaj yeem ua rau muaj cov chaw sib xyaw ua ke yog tias tsis muaj ntau yam. Ib qho ntxiv, tsis tau khob lossis sib tsoo nrog cov roj thooj voos kheej kheej, vim qhov no yuav ua rau kev puas tsuaj rau cov khoom siab siab thiab ua rau tawg.
3. Tsis txhob saib xyuas lub chaw vuam ib puag ncig
Lub chaw vuam ib puag ncig ncaj qha cuam tshuam kev nyab xeeb thiab weld zoo. Tsis quav ntsej kev pheej hmoo ib puag ncig tuaj yeem ua rau muaj xwm txheej lossis cov neeg tsis nkag siab Welds.
Tsis txhob weld nyob rau hauv tsis zoo ventilated uas muaj qhov chaw tsis muaj kev tiv thaiv. Vuam fumes muaj cov teeb meem hnyav xws li cov hlau hnyav (chromium, piv txwv li cov teeb meem ua kom mob ntsws yog tias nqus tau cov nqaij ntshiv. Piv txwv li, stainless hlau vuam ua rau muaj cov tshuaj siab ntawm chromium thiab nickel fumes, uas yog Carcinogenic. Txawm nyob rau hauv qhov chaw qhib, ntev vuam yam tsis muaj qhov cua (xws li nyob rau hauv ib lub ces kaum nqaim) tuaj yeem ua rau fume tsub zuj zuj.
Tsis txhob ua haujlwm ze li cov khoom siv hluav taws xob los yog cov khoom siv tawg. Vuam sparks muaj peev xwm ya mus txog 10 meters deb thiab nyob phws rau ntau li ob peb feeb. Tso roj av, pleev xim, sawdust, lossis lwm yam khoom muaj nplaim taws nyob ze ntawm qhov chaw vuam zoo li tawm hauv lub sijhawm foob pob. Txawm tias cov ntaub ntawv tsis zoo xws li cov khaub ncaws tsis muaj zog xws li cov khaub hlab soaked hauv cov roj tuaj yeem ntes hluav taws thaum raug cov zaub mov. Qee tus neeg ua haujlwm yuav xav tias "Ua kom muaj qhov chaw deb yog txaus," cua ntws tuaj yeem nqa cov txim taws ntxiv, zes nyob sab nraud flammables.
Zam kev vuam ntawm ntub dej lossis cov chaw muaj sia tsis muaj rwb thaiv tsev. Vuam ntawm cov av ntub lossis ncaj qha rau ntawm cov hlau workbench yam tsis muaj kev pheej hmoo ntawm kev pheej hmoo ntawm hluav taws xob ntawm hluav taws xob. Tib neeg lub cev yog tus saib xyuas, thiab yog tias nws tau sib chwv nrog ob tog vuam thiab muaj hluav taws xob ua ke, hluav taws xob hluav taws xob yuav ntws los ntawm lub cev. Ib yam li ntawd, tsis txhob kov tus workpiece thiab cov cuab yeej vuam nrog ob txhais tes tib lub sijhawm thaum tam sim no kom dhau los ntawm lub hauv siab, uas yog qhov txaus ntshai dua li hla dhau ntawm caj npab.
4. Tsis txhob ua txhaum cov khoom tuav thiab cov txheej txheem vuam cov cai
Kev tuav tsis ncaj ncees ntawm cov khoom siv vuam los yog tsis {{0} Taug kev yuav tsis tsuas yog cuam tshuam rau kev nyab xeeb tab sis kuj yuav ua rau muaj kev nyab xeeb rau kev nyab xeeb.
Tsis txhob siv cov khoom siv vuam siv. Kev siv lub vuam vuam pas nrig tsis raug lossis xaim rau lub hauv paus hlau yuav ua rau weld tsis ua hauj lwm. Piv txwv li, siv cov roj carbon steel vuam pas nrig rau weld steel yuav ua rau weld lub zog ntawm tus qauv ntawm tus qauv, uas tej zaum yuav ua txhaum hauv lub nra. Ib qho ntxiv, tsis txhob siv ntub dej, xeb, lossis tas sij hawm vuam rods. Plamp Tsawg - hydrogen welding rods yog nquag los ua cov kab nrib hlau yuav ua rau muaj kev sib tsoo weld, ua rau muaj cov pas dej weld, ua rau pores thiab swb rau cov pores.
Tsis txhob Hla ua ntej -} vuam khoom npaj. Vuam ntawm lub hauv paus ntawm cov hlau hauv qab nrog cov chaw tsis huv (them rau cov xeb, yuav tiv thaiv tus hlau kom zoo nrog cov khoom siv tsis tiav thiab cov hws tsis ua tiav. Rau tuab workpieces uas yuav tsum tau beveling, omitting lub beveling nkag mus, txo lub zog ntawm welded sib koom tes. Qee tus neeg ua haujlwm yuav xav tias "me ntsis xeb yuav tsis muaj teeb meem," tab sis nyob rau hauv cov ntaub ntawv tseem ceeb (xws li tsis xws luag), xws li tsis xws luag los yog txawm tawg.
Zam kev hloov kho ntawm vuam qhov tsis sib tw. Vuam tam sim no, kev voluam, thiab kev taug kev ncig ua si tau txiav txim siab raws cov khoom siv, tuab, thiab vuam txoj kev. Nce tam sim no dhau heev yuav ua rau hlawv -}} los ntawm (rau cov khoom siv nyias) lossis overheating ntawm lub hauv paus hlau, ua rau cov nplej loj hlob thiab brittleness. Txo qhov tam sim no ntau dhau yuav ua rau nkag tsis tau txaus. Kev hloov pauv ntawm kev hloov lub voltage tuaj yeem ua rau arc instability - heev dhau ib qho hluav taws xob, cuam tshuam rau lub arc nplaum, cuam tshuam weld tsim. Qee cov tshuaj tua kab kho kom haum raws li "kev paub" tsis hais txog cov txheej txheem tshwj xeeb, uas muaj kev pheej hmoo, tshwj xeeb yog qhov ua tau zoo.
5. Tsis txhob quav ntsej post - kev ua haujlwm kev nyab xeeb
Kev nyab xeeb ua haujlwm tsis xaus nrog kev ua tiav vuam. Neviewing Post - Cov kauj ruam kev ua haujlwm yuav ua rau muaj xwm txheej xws li hluav taws lossis khoom siv puas.
Tsis txhob cia tawm ntawm cov chaw ua haujlwm tam sim ntawd tom qab vuam. Cov ntaub ntawv welded workpiece thiab cov khoom siv nyob ib puag ncig yuav nyob rau ntawm cov nplaim hluav taws thiab muaj peev xwm ntws tawm hauv cov nplaim txawm tias tom qab arc yog extinguished. Nws yog ib qho tsim nyog nyob rau tsawg kawg 15 {- 30 feeb los xyuas cov hluav taws kub. Piv txwv li, txim taws uas poob rau sawdust lossis ntaub qhwv yuav smolder rau ib lub sijhawm ua ntej tawg rau hauv nplaim taws. Tsis tas li ntawd, tsis txhob teeb tsa combustibles ze rau cov workpieces-txawm tias lawv tsis nyob rau hauv kev tiv tauj ncaj qha, radiant lub tshav kub tuaj yeem nres lawv.
Tsis txhob hnov ​​qab kaw cov khoom siv thiab cov pa hluav taws. Tawm hauv vuam tshuab fais fab yuav ua rau overheating overheating ntawm cov khoom sib xyaw sab hauv, tshwj xeeb tshaj yog tias muaj kev ua txhaum nyob rau hauv lub tshuab txias. Cov roj uas tsis muaj pa roj yuav ua rau qeeb roj ntxiv, uas tuaj yeem ua rau muaj kev phom sij rau lub sijhawm. Rau acetylene thooj voos kheej kheej, txawm tias ib qho xau me me tuaj yeem tsim qhov sib xyaw tawg nrog cua. Tom qab siv tas, ib txwm paub meej tias txhua lub zog hloov thiab cov pa roj roj thiab cov roj yog kaw kom nruj.
Zam kev tuav tsis ncaj ncees ntawm kev tuav pov tseg. Siv vuam vuam pas, slag, thiab hlau scraps yuav tsum tsis txhob muab pov tseg cia li. Kub SLAG tuaj yeem nres khib nyiab, thiab cov ntaub pua av ntse yuav ua rau txiav. Lawv yuav tsum tau sau hauv cov thawv ntim khoom thiab pov tseg tom qab txias.
Hauv cov ntsiab lus, zam cov kev txwv no ntawm kev txiav txim siab rau kev siv vuam yog qhov tseem ceeb kom ntseeg tau kev nyab xeeb thiab weld zoo. Welders yuav tsum ib txwm muaj lub luag haujlwm ntawm lub luag haujlwm, nruj me ntsis kev tswj hwm kev nyab xeeb thiab tsis txhob siv tus cwj pwm txaus ntshai. Tsuas yog ua los ntawm kev ua kom thiaj li muaj xwm txheej yuav tiv thaiv thiab txhim khu kev qha vem kev ua tiav tau tiav.
