1.Yuav tswj cov vuam tam sim no li cas?
Tsis txaus tam sim no: Tsis txaus cua sov, me me los yog tsis muaj weld nugget txoj kab uas hla, uas ua rau lub weld tsis tshua muaj zog. Nyob rau hauv qhov nro thiab shear, nws yog feem ntau cuam tshuam ncaj qha rau ntawm qhov sib koom ua ke (interfacial tearing tsis ua haujlwm).
Ntau dhau tam sim no: Kev kub ceev ceev ua rau cov hlau sab hauv tawg tawm, ua rau tsis yog qhov tsis zoo ntawm qhov chaw vuam zoo (ntau qhov sib sib zog nqus indentations) tab sis kuj ua rau lub zog vuam tsis muaj zog thiab ua rau muaj kev ntxhov siab.
Yuav ua li cas los txiav txim qhov tsim nyog tam sim no: Qhov kev tsim nyog tam sim no yuav tsum tau txiav txim siab los ntawm kev sim ua raws li cov phaj tuab thiab cov khoom siv. Piv txwv li, rau 1.2 hli tuab DP980 siab- lub zog steel, qhov kev pom zoo tam sim no yog 7.5 ~ 9.5 kA; thaum rau DP780 steel, 8-10 kA tuaj yeem siv nyob rau hauv ib qho electrode siab ntawm 3-4 kN. Cov ntsiab cai zoo sib xws tuaj yeem siv rau cov hlau tsis tshua muaj cov pa roj carbon monoxide uas siv hauv cov racks ntau lawm, tab sis cov txiaj ntsig tshwj xeeb yuav tsum tau txheeb xyuas los ntawm cov ntawv xeem.
2.Yuav ua li cas sib npaug vuam lub sij hawm thiab electrode siab?
Lub Sijhawm: Lub sijhawm ua kom muaj zog yuav tsum tau sib phim nrog qhov tam sim no kom ntseeg tau tias kev loj hlob ntawm weld nugget tsis muaj cua sov. Rau cov ntaub ntawv tshwj xeeb, muaj lub sijhawm zoo tshaj plaws.
Siab: Tsis txaus siab ua rau muaj kev tiv thaiv siab, yooj yim ua rau tawg; Kev kub siab ntau dhau ua rau muaj kev sib cuag tsis zoo, yuav tsum muaj kev sib txuas ntxiv hauv vuam tam sim no. Ob leeg yuav tsum tau kho synergistically.
3.Yuav xaiv thiab tswj cov electrodes li cas?
Cov khoom siv hluav taws xob: Rau cov pa txias-cov ntawv hlau dov, chromium- tooj liab (Cr-Cu) lossis chromium-zirconium- tooj liab (Cr-Zr-Cu) alloy electrodes nrog nruab nrab conductivity thiab nruab nrab lub zog yog pom zoo. Cov electrodes no ua tau zoo sib npaug ntawm conductivity thiab tsis kam mus deformation.
Electrode Condition: Lub electrode ua hauj lwm nto yuav tsum tau ceev kom du. Nrog rau cov voj voog txuas ntxiv, lub ntsej muag electrode kawg yuav hnav, deform, lossis ua raws li impurities, ua rau txo qis tam sim no thiab tsis ruaj khov weld zoo. Yog li ntawd, kev saib xyuas electrode tsis tu ncua yog ib txoj kev tseem ceeb.
4.Tom qab welding tiav, koj yuav ua li cas txiav txim siab tias qhov sib koom ua ke yog tsim nyog?
Qhov taw qhia tseem ceeb yog lub weld nugget txoj kab uas hla: lub load- bearing muaj peev xwm ntawm ib tug weld sib koom feem ntau nyob ntawm nws weld nugget txoj kab uas hla. Qhov loj ntawm txoj kab uas hla, qhov siab dua lub zog tensile nws tuaj yeem tiv taus. Kev lag luam feem ntau siv cov qauv ntawm "5√t" (qhov twg t yog lub thickness ntawm cov ntawv hlau) los kwv yees qhov tsawg kawg nkaus weld nugget txoj kab uas hla.
Hom tsis ua haujlwm zoo tshaj plaws: rub- tawm pob tawg: Thaum lub sijhawm kuaj kev puas tsuaj, hom tsis ua haujlwm zoo tshaj plaws yog rub lub "khawm"- zoo li lub qhov nyob rau hauv cov khoom siv puag ncig ntawm qhov sib koom ua ke, es tsis yog qhov sib koom ua ke nws tus kheej zoo sib cais hauv nruab nrab. Qhov no "rub- tawm pob txha" hom qhia tias qhov sib koom ua ke lub zog yog siab dua li ntawm cov khoom siv hauv paus, ib qho cim ntawm kev nkag mus.
5.Dab tsi yog cov ntsiab lus tseem ceeb rau kev ua haujlwm?
Kev Kho Hniav: Txias- cov nplooj ntawv steel feem ntau muaj cov roj stains thiab me ntsis oxide txheej. Txawm hais tias txias - cov ntawv yob yog huv dua li cov ntawv kub - dov, qhov saum npoo yuav tsum tau huv si ua ntej vuam, tsis muaj cov roj ntau, xeb, lossis impurities; txwv tsis pub, spatter los yog tsis tiav welds yuav tshwm sim.
Vuam Specifications: Qhov twg cov cuab yeej muaj peev xwm tso cai, siv "nyuaj specifications" vuam nrog cov tsis muaj siab (siab tam sim no, luv luv) thaum twg los tau. Qhov no pab txhim kho thermal thiab ntau lawm efficiency thaum txo workpiece deformation vim tshav kub.
Kev txhawj xeeb rau Galvanized Sheets: Qhov teeb meem no nyuaj dua thaum siv galvanized txias- cov ntawv dov. Lub xub ntiag ntawm txheej txheej galvanized nqaim lub qhov rais weld thiab yuav tsum muaj qhov vuam tam sim no ntau dua (kwv yees li 2kA ntau dua) los tsim ib qho kev tsim nyog weld nugget. Qhov no yuav tsum muaj kev tswj xyuas qhov tseeb dua.
Kev Tshawb Fawb Daim Ntawv Xeem: Ua ntej ntau lawm lossis tom qab hloov cov khoom siv, nws yog ib qho tseem ceeb uas yuav tsum tau ua cov khoom siv vuam thiab kev puas tsuaj los kuaj xyuas qhov tsim nyog ntawm qhov ntsuas qhov ntsuas.
