Kab lus no piav qhia txog cov hauv paus ntsiab lus, cov khoom siv, cov yam ntxwv ntawm cov txheej txheem, qhov zoo, kev siv, thiab kev tswj xyuas zoo ntawm submerged arc vuam. Nws yog tsim los ua ib qho hauv - qhia tob tob rau engineers, buyers, and industry professionals while being optimized for SEO and readability.
Nkag siab txog cov hauv paus ntawm Submerged Arc Vuam
Submerged Arc Vuam yog txheej txheem fusion welding uas cov arc raug ntaus hauv qab txheej ntawm granular flux. Tsis zoo li qhib- cov txheej txheem arc vuam, lub arc hauv SAW tsis pom thaum lub sijhawm ua haujlwm vim tias nws tau muab zais tag nrho hauv daim pam flux. Qhov no muab kev tiv thaiv los ntawm huab cua paug thiab ua kom muaj kev ruaj khov, siab - vuam qhov chaw ua haujlwm zoo.
Cov txheej txheem siv cov khoom siv tsis tu ncua ntawm cov hlau electrode, nrog rau ob qho tib si electrode thiab cov khoom siv los ntawm cov arc. Lub flux tsis tsuas yog tiv thaiv cov weld tab sis kuj tsim cov slag uas npog lub pas dej molten, tswj cov cua txias thiab ua rau cov khoom zoo.
Cov Cheebtsam tseem ceeb ntawm SAW System
Kev teeb tsa SAW raug suav nrog ntau lub ntsiab lus tseem ceeb, txhua qhov ua rau muaj kev ruaj ntseg thiab qhov tseeb:
• Fais fab mov
• Hlau electrode
• Flux pub mis thiab xa khoom
• Vuam taub hau thiab tswj vaj huam sib luag
• Hlau pub mechanism

• Tsheb thauj mus los lossis siv lub tshuab vuam tshuab
Lub peev xwm los automate tag nrho cov txheej txheem vuam yog ib qho ntawm cov laj thawj tseem ceeb vim li cas SAW tau siv dav hauv kev tsim cov kav ntev welded thiab kauv welded kav.
Yuav Ua Li Cas Submerged Arc Vuam Ua Haujlwm
Thaum lub sij hawm SAW, cov hlau electrode txuas ntxiv mus rau hauv qhov chaw weld qhov twg cov arc melts ob lub hlau thiab lub hauv paus hlau. Granular flux yog tso rau pem hauv ntej ntawm lub arc, tag nrho npog qhov chaw vuam. Raws li welding zuj zus:
- Lub arc generates kub siab heev.
- Lub flux melts thiab tsim ib tug tiv thaiv slag txheej.
- Lub molten slag ntab mus rau saum, tiv thaiv cov hlau weld.
- Lub pas dej weld solidifies nyob rau hauv lub slag.
- Lub slag yog tom qab tshem tawm thaum lub weld txias.
Vim hais tias lub arc yog submerged, cov txheej txheem yog nyob ntsiag to, huv si, thiab muaj peev xwm nkag mus tob heev. Qhov no yog vim li cas SAW feem ntau siv rau hauv vuam tuab daim hlau, loj - txoj kab uas hla, thiab siab - lub zog ntawm cov khoom siv.
Nta ntawm Submerged Arc Vuam
Siab Deposition Rate
SAW tso cai rau tus nqi tso nyiaj ntau dua li kev tuav vuam lossis lwm yam qhib - cov txheej txheem arc. Qhov no ua rau nws zoo tagnrho rau hnyav- lub luag haujlwm kev lag luam.
Sib sib zog nqus Weld Penetration
Nws muaj peev xwm ua tiav kev nkag mus tob kom ntseeg tau tias muaj zog thiab txhim khu kev qha cov pob qij txha, txawm tias nyob rau tuab - cov kav dej uas siv hauv cov kav dej roj thiab roj.
Kev kub ceev vuam
Kev siv cov cuab yeej siv hluav taws xob thiab cov xaim txuas txuas ntxiv tso cai rau SAW kom ua tiav cov khoom lag luam zoo dua piv rau feem ntau cov txheej txheem vuam.
Tsawg Welding Defects
Cov txheej txheej flux tiv thaiv cov vuam los ntawm atmospheric contamination, txo porosity, inclusions, thiab lwm yam weld defects.
Hom Submerged Arc Vuam
Muaj ntau qhov kev hloov pauv ntawm SAW nyob ntawm qhov yuav tsum tau ua ntawm daim ntawv thov:
