Cov yam ntxwv ntawm cov tshuaj muaj pes tsawg leeg

 

Carbon (C) Cov ntsiab lus: Cov ntsiab lus carbon ntawm A32 - qib steel phaj muaj qhov cuam tshuam loj rau weldability. Feem ntau, cov ntsiab lus carbon yog nruab nrab. Yog tias cov ntsiab lus ntawm cov pa roj carbon ntau dhau lawm, cov qauv nyuaj thiab nkig martensite zoo li yuav tsim nyob rau hauv tshav kub - cuam tshuam cheeb tsam thaum vuam. Piv txwv li, thaum cov ntsiab lus ntawm cov pa roj carbon ntau dhau ib qho kev txwv, thaum lub sij hawm txias txias tom qab vuam, vim qhov txias txias ntawm tshav kub - cuam tshuam cheeb tsam, carbon atoms tsis muaj sij hawm txaus rau diffuse thiab martensite yuav tsim. Cov qauv no muaj siab hardness thiab tsis zoo toughness thiab yog nquag mus rau tiam ntawm vuam tawg. Ntawm qhov tod tes, cov ntsiab lus carbon uas tsim nyog pab ua kom lub zog ntawm cov phaj steel thiab tuaj yeem tswj tau qhov zoo ntawm weldability rau qee yam.

 

Cov yam ntxwv ntawm Mechanical Properties

 

Yield Strength thiab Tensile Strength: Lub zog tawm los ntawm A32 - qib steel phaj feem ntau tsis tsawg dua 315MPa, thiab lub zog tensile nyob nruab nrab ntawm 440 - 570MPa. Lub zog muaj zog heev xav kom cov khoom siv vuam sib txuas thiab cov txheej txheem yuav tsum tau sib phim thaum vuam. Yog hais tias lub vuam cua sov input loj dhau lawm, lub zog ntawm cov welded sib koom yuav txo qis thiab nws yuav tsis muaj peev xwm ua tau raws li cov cuab yeej cuab tam ntawm cov khoom siv hauv paus. Vim tias cov khoom siv hluav taws xob ntau dhau yuav ua rau cov nplej ntawm cov hlau vuam thiab cov cua sov - cuam tshuam rau cheeb tsam loj hlob, yog li txo lub zog ntawm kev sib koom ua ke.

 

Cov yam ntxwv ntawm cov txheej txheem vuam

 

Tswj ntawm Vuam Parameters: Vuam tsis xws li vuam tam sim no, voltage, thiab vuam ceev kuj tseem ceeb heev rau cov weldability ntawm A32 - qib steel daim hlau. Siv cov hlau thaiv arc vuam ua piv txwv, qhov vuam tam sim no yuav tsum tau hloov kho raws li txoj kab uas hla ntawm cov electrode thiab thickness ntawm cov hlau phaj. Yog tias qhov tam sim no loj dhau lawm, cov hlau welded yuav dhau los thiab cov nplej yuav ua ntxhib, txo qhov kev ua haujlwm ntawm kev sib koom ua ke. Yog tias qhov tam sim no me me dhau, tsis yog fusion, slag suav nrog thiab lwm yam tsis xws luag yuav tshwm sim. Rau roj - shielded arc vuam thiab submerged arc vuam, nws tseem yuav tsum tau kho kom haum raws li qhov vuam tam sim no, voltage, thiab vuam ceev raws li yam xws li txoj kab uas hla ntawm vuam hlau thiab thickness ntawm cov hlau phaj kom zoo thiab weldability ntawm welded sib koom.

Cov yam ntxwv ntawm Vuam Ib puag ncig

 

Cov av noo: Cov av noo ntawm qhov chaw vuam muaj qhov cuam tshuam loj rau kev vuam zoo thiab weldability ntawm A32 - qib steel phaj. Nyob rau hauv ib qho chaw high-humidity, cov ntsiab lus hydrogen nyob rau hauv weld yog yuav nce. Piv txwv li, thaum tus txheeb ze cov av noo siab, cov av noo nyob rau hauv cov huab cua yuav decompose los tsim hydrogen atoms, thiab cov hydrogen atoms yuav nkag mus rau hauv weld, ua rau hydrogen - induced tawg. Feem ntau, nws raug pom zoo kom weld nyob rau hauv ib puag ncig nrog cov txheeb ze av noo qis dua 90%. Yog tias cov av noo siab, cov cuab yeej dehumidifying tuaj yeem siv los txo cov av noo ib puag ncig, lossis cua - pov thawj thiab los nag - pov thawj ntsuas tuaj yeem ua kom ntseeg tau tias qhov chaw vuam yog qhuav los txhim kho weldability.

 

Kub: Qhov kub thiab txias ambient kuj yog ib qho tseem ceeb. Yog tias qhov kub thiab txias qis dhau, nws yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv vuam thiab cov cua sov hloov thaum lub sij hawm vuam. Feem ntau hais lus, ambient kub yuav tsum tsis txhob qis dua 5 degree, txwv tsis pub siv cov ntsuas kub ua ntej yuav tsum tau ua. Piv txwv li, nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, txheej ntawm cov electrode tuaj yeem ntub dej, cuam tshuam rau kev ruaj ntseg ntawm vuam arc. Nyob rau tib lub sijhawm, qhov cua txias ntawm qhov sib koom ua ke yuav nrawm, thiab nws yooj yim los tsim cov qauv tawv thiab tawg, txo cov weldability.
