Electrode sticking yog qhov tshwm sim ntawm electrode thiab ib feem ua ke thaum lub welder qhov chaw welds thiab cov electrode thiab qhov chaw tsim ib qho txawv txav. Hauv qhov xwm txheej hnyav, cov electrode raug rub tawm thiab cov dej txias ntws ua rau cov khoom xeb.
Muaj plaub qhov laj thawj tseem ceeb rau electrode sticking thaum vuam: qhov chaw ua haujlwm ntawm ob lub electrodes tsis sib npaug, qhov chaw ua haujlwm ntawm cov electrodes yog ntxhib, lub siab electrode tsis txaus, thiab cov yeeb nkab dej ntawm qhov hluav taws xob txias ntawm cov phom vuam yog txuas nyob rau hauv thim rov qab los yog cov dej txias ncig yog thaiv.
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
1. Qhov chaw ua haujlwm ntawm ob lub electrodes tsis yog sib npaug
Thaum qhov chaw ua haujlwm ntawm ob lub electrodes tsis sib npaug, qhov chaw ua haujlwm ntawm cov electrodes yuav nyob rau hauv ib nrab kev sib cuag nrog cov khoom, kev sib cuag ntawm cov electrodes thiab cov khoom yuav nce, thiab tam sim no ntawm vuam Circuit Court yuav txo.
Thaum cov tam sim no yog concentrated nyob rau hauv lub zos qhov chaw, thiab tam sim no ceev ntawm lub contact point yog ntau tshaj qhov tam sim no ceev ntawm qhov chaw ua hauj lwm ntawm lub electrode thaum lub sij hawm ib txwm welding, qhov kub ntawm qhov kev sib cuag taw tes nce mus rau lub weldable kub ntawm lub electrode. thiab ib feem, thiab electrode thiab ib feem yuav fused.
2. Qhov chaw ua haujlwm ntawm cov electrode yog ntxhib
Qhov chaw ua hauj lwm ntawm cov electrode tsis tuaj yeem ua tiav nrog rau qhov, thiab tsuas yog qee qhov protruding qhov chaw nyob rau hauv kev sib cuag nrog ib feem. Qhov xwm txheej no tseem yuav ua rau qhov chaw ua haujlwm ntawm ob lub electrodes tsis yog sib npaug, ua rau cov nplaum nplaum nplaum.
3. Tsis txaus electrode siab
Tiv tauj tiv thaiv yog inversely proportional rau siab. Tsis txaus electrode siab ua rau muaj kev sib cuag ntawm cov electrode thiab ib feem, thiab cov hluav taws xob tiv thaiv ntawm qhov chaw sib cuag tau nce, yog li qhov kub ntawm qhov sib cuag ntawm electrode thiab qhov seem nce mus rau qhov kub ntawm weldable, yog li tsim ib qho kev sib txuas ntawm kev sib cuag. electrode thiab ib feem.
4. Cov yeeb nkab dej ntawm lub vuam phom cua txias qhov hluav taws xob txuas nrog rov qab los yog cov dej txias ntws los yog thaiv
Cov yeeb nkab dej ntawm lub vuam phom cua txias qhov hluav taws xob txuas nrog rov qab los yog cov dej txias ntws tau raug thaiv, cov hluav taws xob kub nce, thiab cov electrode thiab cov khoom tuaj yeem fused thaum lub sij hawm nruam vuam.
Plaub qhov xwm txheej saum toj no yuav ua rau cov khoom siv hluav taws xob thiab cov khoom sib txuas thiab kev sib txuas, uas ua rau muaj qhov tshwm sim ntawm nplaum electrode. Yog li, yuav ua li cas kom tsis txhob muaj qhov tshwm sim ntawm nplaum electrode phenomenon?
(1) Ua ntaub ntawv lub taub hau electrode kom ua haujlwm ntawm ob lub electrodes thaum uas tig mus thiab tsis muaj roughness. Cov txheej txheem vuam tuaj yeem raug xaiv raws li cov txheej txheem sib tsoo (tsis muaj qhov tso tawm tam sim no), thiab qhov chaw ua haujlwm ntawm ob lub tshuab hluav taws xob tuaj yeem raug soj ntsuam kom sib npaug los ntawm kev tua phom vuam.
(2) Nyob rau hauv lub xeev sib tsoo, tua phom vuam 5 mus rau 10 lub sij hawm rau forge lub chaw ua hauj lwm ntawm ob lub electrodes kom muaj kev sib cuag cheeb tsam nyob rau hauv lub cheeb tsam ntawm electrode taub hau thiab txhim kho qhov hardness.
(3) Thaum tshav kub kub ua hauj lwm nto ntawm lub electrode nrog ib tug nplaim hluav taws oxyacetylene los tsim ib tug oxide txheej (oxide txheej) rau ntawm qhov chaw ua hauj lwm ntawm lub electrode, uas yuav ua rau kom lub melting point ntawm lub chaw ua hauj lwm ntawm lub electrode thiab rhuav tshem lub weldability ntawm lub electrode thiab ib feem.
(4) Siv cov hlau lead liab uas npaj los ntawm cov welder mus rau qhov chaw ua haujlwm ntawm cov electrode los rhuav tshem cov weldability ntawm cov electrode thiab ib feem.
(5) Kho cov electrode siab thiab siv vuam tsis muaj kev kub siab, lub zog loj thiab lub sijhawm luv zog.
(6) Ntxuav cov kav dej txias kom tsis tu ncua kom cov dej txias ntws. Cov saum toj no yog tag nrho cov kev ntsuas uas yuav daws tau qhov teeb meem ntawm sticking electrodes thaum vuam.
