Yuav ua li cas los xyuas kom meej qhov rov ua haujlwm raug ntawm cov neeg hlau vuam?
Qhov tseeb ntawm cov vuam neeg hlau raug cuam tshuam los ntawm ntau yam, nrog rau kev thauj khoom ntawm cov neeg hlau caj npab, hnav cov cuab yeej, qhov nyuaj ntawm vuam workpieces, thiab lwm yam. Ntxiv nrog rau kev siv cov cuab yeej ntsuas siab, qhov tseeb kuj tuaj yeem raug them los ntawm welding auxiliary khoom thiab vuam tswj system. Thiab nrog kev txhim kho txuas ntxiv thiab kev txhim kho ntawm vuam neeg hlau thev naus laus zis, qhov yuam kev xav tau los ntawm vuam neeg hlau rau vuam yog qhov me me.
1. Muab cov txheej txheem vuam tsim nyog
Cov txheej txheem vuam tsim nyog rau vuam neeg hlau yuav tsum tau muab tso ua ke, thiab qhov loj me, vuam zawj thiab qhov sib dhos loj yuav tsum raug tswj nruj me ntsis thaum lub sijhawm ua haujlwm. Qhov ntev ntev ntawm qhov dav dav thiab qhov zawj yuav tsum tswj tsis pub dhau ± 0.8mm, thiab qhov sib dhos qhov yuam kev yuav tsum tswj tsis pub dhau ± 1.5mm. Qhov tshwm sim ntawm vuam tsis xws li porosity thiab undercut nyob rau hauv lub vuam yuav txo tau heev.
2. Sib piv cov cuab yeej pabcuam kom ntseeg tau qhov tseeb
Cov cuab yeej sib dhos nrog qhov raug siab yog siv los txhim kho kev sib dhos qhov tseeb ntawm qhov vuam. Lub vuam positioner tuaj yeem rub lub vuam mus rau qhov vuam ntau ntawm cov phom vuam, uas tuaj yeem txo qhov kev ncua deb ntawm vuam thiab vuam phom. Nws yog qhov tsim nyog rau cov phom vuam los tso cov khoom siv vuam tsuas yog los sau cov vuam, thiab xyuas kom cov vuam zoo nkauj thiab ruaj khov. Lub tshuab tsis siv neeg taug qab ntawm qhov vuam yog tias qhov kev tswj xyuas tuaj yeem ua tiav qhov vuam vuam los ntawm kev txheeb xyuas qhov vuam specification thiab kho qhov tsim nyog vuam tsis tau los ntawm kev tswj qhov system.
3. Load peev xwm ntawm vuam neeg hlau caj npab
Lub vuam neeg hlau tuaj yeem paub qhov ruaj khov vuam nyob rau hauv ib puag ncig hnyav, uas tau txais txiaj ntsig los ntawm lub peev xwm ntawm lub tshuab vuam. Yog tias qhov hnyav ntawm qhov vuam yog tswj nyob rau hauv lub peev xwm thauj khoom ntawm vuam neeg hlau caj npab, vuam neeg hlau caj npab tuaj yeem ruaj khov vuam zoo thaum ua kom muaj kev ywj pheej, thiab cov neeg hlau caj npab tuaj yeem paub qhov tseeb vuam thaum lub sij hawm viav vias txheej txheem.
4. Khaws cov khoom siv kom huv si
Lub weld yuav tsum huv si. Ua ntej welding, nws yuav tsum xyuas kom meej tias tsis muaj roj stain, xeb, vuam slag, txiav slag thiab lwm yam sundries. Weldable primer tau tso cai. Txwv tsis pub, qhov kev vam meej ntawm arc tawm tsam yuav raug cuam tshuam. Lub tack welding yog hloov los ntawm electrode welding mus rau roj shielded vuam, thiab qhov chaw vuam ib feem yog polished nyob rau tib lub sij hawm kom tsis txhob lub slag plhaub los yog huab cua qhov tshuav los ntawm lub tack welding, thiaj li yuav zam lub instability ntawm lub arc thiab txawm lub tiam ntawm spatter.
5. Ntau txheej thiab ntau txoj kev vuam
Multi txheej thiab multi pass welding yog tso nyiaj ntau tshaj ob txheej txheej vuam kom tiav cov vuam ntawm tag nrho cov vuam. Nyob rau hauv txoj kev no, lub tshav kub input yog me me nyob rau hauv tus txheej txheem ntawm rov ua hauj lwm, uas yuav txo tau qhov tshwm sim ntawm vuam tsis xws luag thiab xyuas kom meej qhov tseeb nyob rau hauv rov ua hauj lwm.
