1. Kev tswj ntawm qhov sib txawv ntawm qhov sib txawv: Tom qab dov los ntawm ntau lub chais, cov sawb hlau xa mus rau chav tsev welded yeeb nkab. Lub sawb hlau yog maj mam dov los ua ib lub raj puag ncig uas muaj qhov sib txawv ntawm cov hniav. Kho tus nqi nias ntawm lub tshuab nyem kom tswj tau qhov sib txawv ntawm qhov sib txawv ntawm 1 thiab 3 hli thiab ua kom cov weld xaus flush. Yog hais tias qhov sib txawv loj heev, qhov sib thooj nyhuv yuav raug txo, qhov eddy tam sim no tsis muaj, thiab weld crystals yuav ncaj qha txuas tsis zoo thiab unfused los yog tawg. Yog tias qhov sib txawv me me dhau lawm, qhov sib thooj ntawm qhov sib thooj yuav nce, qhov vuam kub yuav loj dhau, thiab qhov vuam yuav raug hlawv; Tej zaum cov weld yuav tsim ib lub qhov tob tom qab extrusion thiab dov, uas yuav cuam tshuam rau cov tsos ntawm weld.

2. Kev tswj qhov kub thiab txias: Raws li cov qauv, qhov vuam kub yog cuam tshuam los ntawm lub zog hluav taws xob siab eddy tam sim no. Lub high-frequency eddy tam sim no cua sov lub zog yog cuam tshuam los ntawm tam sim no zaus, thiab eddy tam sim no cua sov lub zog yog proportional rau lub square ntawm lub tam sim no kev txhawb zog zaus; thiab qhov kev txhawb zog tam sim no yog cuam tshuam los ntawm kev txhawb nqa voltage, tam sim no, capacitance, thiab inductance. Inductance = sib nqus flux / tam sim no Nyob rau hauv cov mis: f-txhawb zaus (Hz-txhawb lub capacitance nyob rau hauv lub voj (F capacitance = hluav taws xob / voltage; L-txhawb lub inductance nyob rau hauv lub voj). lub hauv paus square ntawm inductance nyob rau hauv lub voj kev txhawb nqa). ncav cuag lub hom phiaj ntawm kev tswj cov vuam kub txog qhov tsawg carbon steel, vuam kub yog tswj ntawm 1250 ~ 1460 ℃, nws muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm cov yeeb nkab phab ntsa thickness ntawm 3 ~ 5 hli nkag mus rau vuam kub kuj tuaj yeem hloov kho Qhov vuam ceev ntawm ntug ntawm lub vuam vuam tsis tuaj yeem ncav cuag qhov kub ntawm qhov vuam thaum tsis muaj qhov cua sov, cov qauv hlau tseem ruaj khov thiab ua rau tsis txaus fusion lossis tsis tiav; Thaum cov khoom siv hluav taws xob tsis muaj, cov ntug ntawm cov welded welded yuav dhau qhov kub ntawm qhov vuam, ua rau overburning los yog tee dej, ua rau cov weld tsim ib lub qhov molten.

3. Kev tswj lub zog squeezing: nyob rau hauv qhov nyem ntawm lub tshuab nyem, ob lub npoo ntawm lub raj khoob yog rhuab mus rau qhov kub thiab txias. Cov hlau siv lead ua nplej uas pleev ua ke nkag mus thiab crystallize ib leeg, thiab thaum kawg tsim ib qho kev sib txuas. Yog tias lub zog extrusion tsawg dhau lawm, cov khoom siv lead ua yuav me me, thiab lub zog ntawm cov hlau vuam yuav txo qis, thiab cov kab nrib pleb yuav tshwm sim tom qab siv zog; Yog hais tias lub extrusion quab yuam loj dhau lawm, cov hlau molten yuav raug nyem tawm ntawm lub vuam, tsis tsuas yog txo lub zog ntawm cov weld yog txhim kho, thiab ntau qhov chaw thiab sab hauv burrs yuav tshwm sim, thiab txawm tias tsis xws luag xws li weld lap joints yuav. raug tsim.

4. Kev hloov kho ntawm txoj hauj lwm ntawm high-frequency induction coil: lub sij hawm cua kub zoo yog ntev dua, thiab high-frequency induction coil yuav tsum nyob ze li sai tau rau txoj hauj lwm ntawm lub tshuab nyem. Yog hais tias lub voj induction nyob deb ntawm lub tshuab nyem. Lub tshav kub cuam tshuam yog dav dua thiab lub zog ntawm cov vuam raug txo; Ntawm qhov tsis sib xws, ntug ntawm cov vuam tsis muaj cua sov, ua rau cov pwm tsis zoo tom qab extrusion. Qhov chaw hla ntu ntawm cov resistor yuav tsum tsis pub tsawg dua 70% ntawm qhov chaw hla ntu ntawm sab hauv txoj kab uas hla ntawm cov yeeb nkab steel. Nws cov nyhuv yog ua kom lub induction kauj, ntug ntawm cov yeeb nkab tsis muaj vuam, thiab cov hlau nplaum sib nqus ua ib lub voj voog electromagnetic induction.

5. Lub resistor yog ib los yog ib pab pawg neeg tshwj xeeb sib nqus rods rau welded kav. . Qhov sib thooj tshwm sim tshwm sim, thiab eddy tam sim no cua sov yog concentrated nyob ze ntawm ntug ntawm lub vuam ntawm lub raj dawb paug kom lub ntug ntawm lub raj dawb paug yog rhuab mus rau lub vuam kub. Lub resistor yog rub rau hauv lub raj nrog cov hlau hlau, thiab qhov chaw nruab nrab yuav tsum tau kho nyob ze ntawm qhov nruab nrab ntawm lub tshuab nyem. Thaum pib, vim qhov ceev ceev ntawm lub raj tsis muaj zog, cov cuab yeej tiv thaiv tau hnav zoo heev los ntawm kev sib txhuam ntawm sab hauv phab ntsa ntawm lub raj khoob thiab yuav tsum tau hloov ntau zaus.

6. Weld caws pliav yuav tshwm sim tom qab vuam thiab extrusion. Relying ntawm ceev ceev ntawm lubwelded steel yeeb nkab, weld caws pliav yuav flattened. Cov burrs hauv cov yeeb nkab welded feem ntau tsis huv.
