Argon arc vuam txoj kev ua haujlwm
Argon arc yog ib qho kev ua haujlwm uas sab laug thiab sab tes xis txav tib lub sijhawm, uas yog tib yam li kos duab voj voog nrog sab laug tes thiab kos duab square nrog sab tes xis hauv peb lub neej niaj hnub.Yog li ntawd, nws raug pom zoo tias cov neeg uas nyuam qhuav pib kawm argon arc vuam muaj kev cob qhia zoo sib xws, uas yuav pab tau rau kev kawm argon arc vuam.
(1) Hlau pub: muab faib ua cov xaim sab hauv thiab sab nrauv xaim.
Sab nrauv muab tub lim tuaj yeem siv rau priming thiab filling.Nws siv lub zog loj.Lub taub hau vuam hlau yog nyob rau pem hauv ntej ntawm qhov zawj.Sab laug tes pinches lub vuam hlau thiab txuas ntxiv xa mus rau hauv lub pas dej molten rau vuam.Qhov sib txawv ntawm qhov zawj yuav tsum tau me me lossis tsis muaj qhov sib txawv.
Nws qhov zoo yog kev ua haujlwm siab ntau lawm thiab kev ua haujlwm yooj yim vim qhov loj tam sim no thiab qhov sib txawv me me.Nws qhov tsis zoo yog tias nws yog siv rau hauv qab, vim tias tus neeg teb xov tooj tsis tuaj yeem pom qhov melting ntawm blunt ntug thiab lub zog ntawm sab nraub qaum, nws yog ib qho yooj yim los tsim unfused thiab tsis tau txais qhov zoo tagnrho rov qab tsim.
Sab hauv muab tub lim tsuas yog siv tau rau kev rov qab vuam.Siv tus ntiv tes xoo, ntiv tes ntiv tes los yog ntiv tes nruab nrab ntawm koj sab tes laug los tswj txoj kev pub mis.Tus ntiv tes me me thiab ntiv tes ntiv tes tuav lub vuam hlau los tswj kev taw qhia.Lub vuam hlau yog nyob ze rau ntawm ntug blunt nyob rau hauv lub zawj thiab melts ua ke nrog lub blunt ntug Rau welding, qhov zawj qhov sib txawv yuav tsum tau loj tshaj li txoj kab uas hla ntawm vuam hlau.Yog tias nws yog ib lub phaj, lub vuam hlau tuaj yeem khoov rau hauv ib qho arc.
Nws qhov zoo dua yog vim tias cov vuam hlau nyob ntawm qhov sib txawv ntawm qhov zawj, qhov blunt ntug thiab cov txheej txheem melting ntawm vuam hlau tuaj yeem pom meej meej, thiab qhov rov qab qhov cuab yeej tuaj yeem pom los ntawm qhov muag pom ntawm lub qhov muag, yog li ntawd, weld fusion yog qhov zoo, thiab qhov kev txhawb nqa rov qab thiab tsis yog fusion tuaj yeem tau txais kev tswj xyuas zoo.Qhov tsis zoo yog qhov kev ua haujlwm nyuaj, thiab cov welder yuav tsum muaj kev txawj ua haujlwm ntau dua.Vim tias qhov sib txawv loj, qhov vuam ntim yuav nce raws li.Qhov sib txawv yog qhov loj, yog li qhov tam sim no tsis tshua muaj, thiab kev ua haujlwm ua haujlwm qeeb qeeb dua li ntawm cov xaim xaim sab nraud.
(2) Welding handles muab faib ua crank handles thiab mops.
Kev tuav tuav yog nias lub vuam nozzle me ntsis ntawm lub vuam seam, thiab co caj npab zoo heev rau vuam.Nws qhov zoo yog vim lub vuam nozzle yog nias rau ntawm lub vuam seam, thiab vuam kov yog ruaj khov heev thaum lub sij hawm ua haujlwm, yog li cov vuam seam muaj kev tiv thaiv zoo, qhov zoo yog qhov zoo, zoo nkauj heev, thiab cov khoom tsim nyog tus nqi yog siab. .Tau txais cov xim zoo nkauj heev.Qhov tsis zoo yog tias nws yog qhov nyuaj rau kev kawm, vim hais tias caj npab shakes ntau, yog li nws yog tsis yooj yim sua rau weld ntawm obstacles.
Lub tshuab ntxhua khaub ncaws txhais tau hais tias lub vuam ntswj leans maj mam los yog tsis lean ntawm lub vuam seam, tus ntiv tes me me los yog ntiv tes ntiv tes ntawm sab tes xis kuj leans los yog tsis lean ntawm lub workpiece, caj npab swings me me, thiab rub lub vuam kov. rau vuam.Nws qhov zoo dua yog tias nws yooj yim kawm thiab muaj qhov hloov tau zoo.Nws qhov tsis zoo yog tias cov duab thiab qhov zoo tsis zoo, tshwj xeeb tshaj yog rau kev siv nyiaj siv ua haujlwm tsis muaj shaker los pab txhawb kev vuam.Nws yog qhov nyuaj kom tau txais cov xim zoo nkauj thiab cov duab thaum vuam stainless hlau.
(3) Arc ignition: Arc ignition feem ntau yog siv (high-frequency oscillator los yog high-frequency pulse generator), thiab tungsten electrode thiab weldment tsis hu rau ignite arc.Thaum tsis muaj arc ignition, hu rau arc ignition yog siv (feem ntau yog siv nyob rau hauv kev tsim kho qhov chaw) installation, tshwj xeeb tshaj yog high-altitude installation), tooj liab los yog graphite yuav muab tso rau ntawm qhov zawj ntawm weldment rau ntaus arc, tab sis txoj kev no yog ntau. teeb meem thiab siv tsawg dua.Feem ntau, lub teeb stroke nrog lub vuam hlau ua rau cov vuam thiab cov tungsten electrode ncaj qha luv luv thiab txiav tawm sai.Thiab ignite lub arc.
(4) Vuam: Tom qab lub arc yog ignited, nws yuav tsum tau preheat rau 3-5 vib nas this thaum pib ntawm weldment, thiab pib xaim pub tom qab lub molten pas dej ua ke yog tsim.Thaum welding, lub kaum sab xis ntawm vuam hlau teeb yuav tsum tsim nyog, thiab vuam hlau yuav tsum tau pub tusyees.Lub vuam teeb yuav tsum txav mus rau pem hauv ntej kom du, viav vias sab laug thiab sab xis me ntsis qeeb ntawm ob sab, thiab me ntsis nrawm dua hauv nruab nrab.Ua tib zoo mloog cov kev hloov pauv ntawm lub pas dej molten.Thaum lub pas dej molten loj dua, qhov vuam seam yuav dav dua, los yog lub vuam seam yuav concave, vuam ceev yuav tsum tau nce los yog vuam tam sim no yuav tsum tau txo dua.Thaum lub fusion ntawm lub pas dej molten tsis zoo thiab cov hlau tsis tuaj yeem noj, nws yog ib qho tsim nyog los txo qhov vuam ceev los yog nce qhov vuam tam sim no.Yog tias nws yog qhov vuam hauv qab, lub qhov muag yuav tsum tsom rau ntawm cov npoo ntawm ob sab ntawm qhov zawj, thiab cov ces kaum ntawm lub qhov muag.Lub teeb peripheral yog nyob rau sab nraud ntawm qhov slit, thiab xyuam xim rau kev hloov ntawm lwm qhov siab.
5) Arc extinguishing: Yog hais tias lub arc yog extinguished ncaj qha, nws yog ib qho yooj yim los tsim shrinkage kab noj hniav.Yog hais tias lub welding torch muaj ib tug arc pib, lub arc yuav tsum tau kaw intermittently los yog hloov mus rau ib tug tsim nyog arc crater tam sim no.Lub arc yog coj mus rau ib sab ntawm qhov zawj, thiab tsis muaj qhov shrinkage yog tsim.Yog hais tias lub qhov shrinkage tshwm sim, nws yuav tsum tau polished ua ntej welding.
Yog tias lub arc nyob ntawm qhov sib koom ua ke, qhov sib koom ua ke yuav tsum tau muab tso rau hauv ib qho bevel ua ntej, thiab tom qab ntawd welded rau pem hauv ntej 10-20mm tom qab kev sib koom ua ke yog tag nrho melted, thiab tom qab ntawd lub arc kaw maj mam, thiab tsis muaj kab noj hniav tuaj yeem tshwm sim.Hauv kev tsim khoom, nws feem ntau pom tias cov pob qij txha tsis polished rau hauv bevels, thiab lub sijhawm vuam ntawm cov pob qij txha yog ncaj qha lengthened rau cov pob qij txha.Qhov no yog ib tug cwj pwm phem heev.Nyob rau hauv txoj kev no, cov pob qij txha yog qhov yooj yim rau concave, cov pob qij txha tsis fused thiab sab nraub qaum yog tawm ntawm kev sib koom ua ke, uas yuav cuam tshuam rau qhov zoo ntawm cov duab.Yog hais tias nws yog ib tug siab alloy Cov khoom kuj yog ib qho yooj yim mus tawg.
