1. Kev faib tawm
Arc vuam tuaj yeem muab faib uaphau ntawv arc vuam, semi-automatic (arc) vuam, tsis siv neeg (arc) vuam. Tsis siv neeg (arc) welding feem ntau yog hais txog submerged arc tsis siv neeg vuam - qhov chaw vuam yog npog nrog txheej tiv thaiv ntawm flux, photonic hlau ua los ntawm muab tub lim hlau yog ntxig rau hauv cov txheej txheem flux, thiab vuam hlau tsim ib qho arc, arc yog faus rau hauv cov txheej txheem flux, thiab cov cua sov tsim los ntawm cov arc melts cov txheej txheem weld thiab cov txheej txheem hlau. tsis siv neeg. Feem ntau siv yog phau ntawv arc vuam.
2. Cov txheej txheem yooj yim
Cov txheej txheem yooj yim ntawm phau ntawv arc vuam yog raws li hauv qab no: a. Ntxuav lub vuam nto ua ntej vuam kom tsis txhob cuam tshuam qhov zoo ntawm arc ignition thiab vuam seam. b. Npaj daim ntawv sib koom ua ke (groove hom). Lub luag hauj lwm ntawm qhov zawj yog ua kom vuam pas nrig, vuam hlau los yog lub teeb (nozzle uas txau cov nplaim acetylene-oxygen thaum lub vuam vuam) ncaj qha mus rau hauv qab ntawm qhov zawj kom ntseeg tau tias vuam nkag mus, thiab yog qhov tsim nyog rau kev tshem tawm slag thiab yooj yim rau qhov tsim nyog oscillation ntawm cov vuam pas nrig kom tau txais qhov zoo. Cov duab thiab qhov loj ntawm qhov zawj feem ntau yog nyob ntawm cov khoom siv welded thiab nws cov specifications (feem ntau thickness), nrog rau cov vuam txoj kev saws, daim ntawv ntawm weld seam, thiab lwm yam. Feem ntau grooved hom nyob rau hauv cov kev siv yog: nkhaus pob qij txha - haum rau nyias qhov chaw nrog ib tug thickness ntawm <3 hli; Pav ca zawj - haum rau nyias qhov chaw ntawm 3 ~ 8mm; V-shaped zawj - haum rau workpieces nrog lub thickness ntawm 6 ~ 20mm (ib leeg-sab vuam); Schematic daim duab ntawm weld zawj hom X groove - haum rau workpieces nrog ib tug tuab ntawm 12 ~ 40mm, thiab muaj symmetrical thiab asymmetrical X grooves (ob-sided vuam); U-shaped zawj - haum rau workpieces nrog lub thickness ntawm 20 ~ 50mm (ib leeg-sab vuam); Ob chav U-puab zawj - haum rau workpieces nrog ib tug tuab ntawm 30 ~ 80mm (ob-sided vuam). Lub kaum sab xis feem ntau yog los ntawm 60 mus rau 70 °, thiab lub hom phiaj ntawm kev siv cov npoo npoo (tseem hu ua qhov siab hauv paus) yog los tiv thaiv vuam los ntawm kev kub hnyiab, thaum qhov sib txawv yog txhawm rau txhawm rau vuam nkag.
3.Main parameters
Qhov tseem ceeb tshaj plaws nyob rau hauv lub vuam specifications ntawm arc vuam yog: vuam pas nrig hom (nyob ntawm seb cov khoom ntawm lub hauv paus khoom), electrode txoj kab uas hla (nyob ntawm seb lub thickness ntawm weld, weld txoj hauj lwm, tus xov tooj ntawm vuam txheej, vuam ceev, vuam tam sim no, thiab lwm yam), vuam tam sim no, vuam txheej, thiab lwm yam. Nws kuj tseem siv tau: gas shielded arc vuam: piv txwv li,argon arc vuamsiv argon ua cov roj tiv thaiv hauv qhov chaw vuam, carbon dioxide shielded vuam siv cov pa roj carbon dioxide ua cov roj thaiv hauv qhov chaw vuam, thiab lwm yam, lub hauv paus ntsiab lus tseem ceeb yog welding nrog arc raws li qhov cua sov, thiab tib lub sij hawm tsis tu ncua txau cov roj tiv thaiv los ntawm lub nozzle ntawm rab phom txau kom cais cov huab cua los ntawm cov hlau molten nyob rau hauv cov hlau welding los tiv thaiv cov pa oxygen nyob rau hauv qhov chaw welding. nitrogen, Hydrogen thiab lwm yam kev ua qias tuaj kom ua tiav lub hom phiaj ntawm kev txhim kho qhov zoo ntawm vuam. Tungsten argon arc vuam: hlau tungsten pas nrig nrog lub siab melting point yog siv los ua ib qho hluav taws xob uas tsim cov arc thaum vuam, thiab arc vuam nyob rau hauv kev tiv thaiv ntawm argon, uas yog feem ntau siv nyob rau hauv stainless hlau, high-temperature alloy thiab lwm yam vuam uas yuav tsum tau nruj me ntsis. Plasma arc vuam: Qhov no yog ib txoj kev vuam tsim los ntawm tungsten argon arc vuam, nyob rau hauv lub nozzle aperture ntawm lub tshuab Arc vuam tam sim no loj kev txiav txim: me me tam sim no: nqaim vuam hlaws, ntiav nkag, yooj yim rau tsim siab dhau lawm, tsis fused, tsis welded los ntawm, slag, porosity arc, weld, arc vuam, thiab lwm yam. Tam sim no loj: lub weld hlaws yog dav, qhov tob ntawm kev nkag mus yog loj, qhov tom ntug, qhov kub hnyiab, qhov shrinkage, qhov txaws yog loj, overburn, deformation loj, weld qog thiab lwm yam.
