Dab tsi yog qhov tseem ceeb cuam tshuam rau kev sib txuas ntawm electrode?

Lub vuam tsis muaj electrode arc vuam feem ntau muaj xws li electrode txoj kab uas hla, vuam tam sim no, arc voltage, tus naj npawb ntawm vuam txheej, lub hwj chim qhov chaw thiab polarity, thiab lwm yam.

1. Kev xaiv ntawm electrode txoj kab uas hla

Qhov kev xaiv ntawm txoj kab uas hla ntawm electrode feem ntau yog nyob ntawm yam xws li lub thickness ntawm lub vuam, hom kev sib koom tes, txoj hauj lwm ntawm vuam thiab qib vuam.Nyob rau ntawm qhov chaw uas tsis cuam tshuam rau vuam zoo, txhawm rau txhim kho cov khoom tsim tau zoo, feem ntau nyiam xaiv cov kab hluav taws xob loj dua.

Rau vuam qhov chaw nrog lub thickness loj, yuav tsum tau siv ib txoj kab uas hla loj electrode.Rau cov vuam tiaj tiaj, txoj kab uas hla ntawm cov electrode siv tuaj yeem loj dua;rau ntsug vuam, txoj kab uas hla ntawm cov electrode siv tsis ntau tshaj 5 hli;rau kab rov tav vuam thiab nyiaj siv ua haujlwm vuam, txoj kab uas hla ntawm cov electrode siv feem ntau tsis tshaj 4 hli.Nyob rau hauv cov ntaub ntawv ntawm ntau txheej welding nrog sib npaug grooves, txhawm rau tiv thaiv qhov tshwm sim ntawm kev nkag mus tsis tiav, 3.2 hli txoj kab uas hla electrode yuav tsum tau siv rau thawj txheej ntawm vuam.Raws li ib txwm muaj, cov kab hluav taws xob electrode tuaj yeem xaiv raws li qhov tuab ntawm cov vuam (raws li teev nyob rau hauv Table TQ-1).

2. Kev xaiv ntawm vuam tam sim no

Qhov loj ntawm vuam tam sim no muaj kev cuam tshuam zoo rau kev vuam zoo thiab tsim khoom.Yog tias qhov tam sim no me me dhau lawm, lub arc tsis ruaj khov, thiab nws yooj yim los ua qhov tsis xws luag xws li slag inclusion thiab incomplete penetration, thiab productivity yog tsawg;Yog tias qhov tam sim no loj dhau, qhov tsis xws luag xws li undercut thiab hlawv-los ntawm qhov yuav tshwm sim, thiab spatter nce.

Yog li ntawd, thaum vuam nrog electrode arc vuam, vuam tam sim no yuav tsum tsim nyog.Qhov loj ntawm qhov vuam tam sim no yog txiav txim siab los ntawm yam xws li hom electrode, electrode txoj kab uas hla, weldment thickness, sib koom ua ke, weld qhov chaw qhov chaw thiab vuam theem, qhov tseem ceeb tshaj plaws yog electrode txoj kab uas hla thiab weld qhov chaw.Thaum siv cov txheej txheem steel electrodes, kev sib raug zoo ntawm cov vuam tam sim no thiab cov kab hluav taws xob electrode tuaj yeem raug xaiv los ntawm cov qauv empirical: I = kd

Hauv cov qauv, kuv sawv cev rau qhov vuam tam sim no (A);sawv cev rau lub electrode txoj kab uas hla (mm);

k sawv cev rau cov coefficient ntsig txog txoj kab uas hla ntawm cov electrode (saib TQ-2 rau xaiv).

Tsis tas li ntawd, txoj hauj lwm spatial ntawm vuam yog txawv, thiab qhov loj ntawm qhov vuam tam sim no kuj txawv.Feem ntau, tam sim no nyob rau hauv ntsug welding yuav tsum yog 15% ~ 20% qis dua qhov hauv vuam vuam;Qhov tam sim no ntawm kab rov tav vuam thiab nyiaj siv ua haujlwm vuam yog 10% ~ 15% qis dua li hauv vuam vuam.Lub vuam thickness yog loj, thiab lub sab sauv txwv ntawm tam sim no yog feem ntau coj.

Alloy steel electrodes nrog ntau alloying ntsiab feem ntau muaj ntau dua hluav taws xob tsis kam, loj thermal expansion coefficient, siab tam sim no thaum vuam, thiab cov electrode yog nquag redness, ua rau lub txheej poob tawm ntxov ntxov, cuam tshuam rau vuam zoo, thiab cov alloying ntsiab yog hlawv. ntau, yog li welding Cov tam sim no raug txo raws li.

3. Kev xaiv ntawm arc voltage

Lub arc voltage yog txiav txim los ntawm qhov ntev arc.Yog hais tias lub arc ntev, lub arc voltage yog siab;Yog hais tias lub arc yog luv, lub arc voltage yog tsawg.Nyob rau hauv cov txheej txheem vuam, yog hais tias lub arc ntev dhau lawm, lub arc yuav hlawv tsis ruaj, spatter yuav nce, kev nkag mus yuav txo, thiab cov huab cua sab nraud yuav yooj yim invade tib neeg, ua rau tsis xws luag xws li pores.Yog li ntawd, qhov ntev arc yuav tsum tsawg dua los yog sib npaug ntawm txoj kab uas hla ntawm cov electrode, uas yog, luv luv arc vuam.Thaum siv cov kua qaub electrode rau vuam, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau welding, nws raug nquahu kom siv cov txheej txheem welded los yog txo qhov kub ntawm lub pas dej molten, qee zaum lub arc yog me ntsis stretched rau vuam, thiaj li hu ua ntev arc vuam.

4. Kev xaiv ntawm tus naj npawb ntawm vuam txheej

Multi-layer welding feem ntau yog siv rau hauv arc vuam ntawm nruab nrab thiab tuab daim hlau.Ntau cov khaubncaws sab nraud povtseg muaj txiaj ntsig los txhim kho cov yas thiab tawv tawv ntawm cov vuam, tshwj xeeb tshaj yog rau cov kab mob khaub thuas.Txawm li cas los xij, nws yog ib qho tsim nyog los tiv thaiv cov teeb meem cuam tshuam ntawm overheating qhov sib koom ua ke thiab nthuav dav rau thaj tsam uas cuam tshuam los ntawm tshav kub.Tsis tas li ntawd, qhov nce ntawm cov khaubncaws sab nraud povtseg yuav ua rau kom qhov deformation ntawm cov welding.Yog li ntawd, nws yuav tsum tau txiav txim siab los ntawm kev xav zoo.

5. Kev xaiv lub hwj huam mov hom thiab polarity

DC fais fab mov muaj qhov ruaj khov arc, me me spatter thiab zoo vuam zoo.Nws yog feem ntau siv rau vuam tseem ceeb vuam qauv los yog tuab daim hlau nrog loj rigidity lug.

Hauv lwm qhov xwm txheej, koj yuav tsum xub xav txog kev siv lub tshuab AC vuam, vim tias AC vuam tshuab muaj cov qauv yooj yim, tus nqi qis, thiab yooj yim rau siv thiab tswj dua li DC vuam tshuab.Kev xaiv ntawm polarity yog nyob ntawm qhov xwm ntawm cov electrode thiab cov yam ntxwv ntawm vuam.Qhov kub ntawm lub anode nyob rau hauv lub arc yog siab tshaj qhov kub ntawm lub cathode, thiab sib txawv polarities yog siv los welding ntau yam weldments.
