Dab tsi yog cov txiaj ntsig laser vuam
Cov Nyiaj Vuam Laser
(1) Qhov yuav tsum tau muaj ntawm cov cua sov tuaj yeem txo mus rau qhov tsawg kawg nkaus, thiab qhov ntau ntawm kev hloov pauv hauv thaj tsam tshav kub yog qhov me me, thiab kev hloov pauv los ntawm kev sib cais cov cua sov kuj yog qhov qis;
(2) Lub sijhawm ua haujlwm vuam txwv ntawm 32mm phaj tuab ib leeg vuam vuam ib leeg tau raug txheeb xyuas kom ua tiav, uas tuaj yeem txo lub sijhawm siv cov tuab tuab vuam vuam thiab txawm txuag kev siv cov hlau;
(3) Tsis tas yuav siv cov electrode, tsis muaj electrode paug lossis kev txhawj xeeb kev puas tsuaj. Thiab vim tias nws tsis zwm rau qhov kev sib tiv tauj vuam txheej txheem, qhov poob thiab deformation ntawm lub tshuab thiab cov cuab yeej tuaj yeem txo kom tsawg;
(4) lub lasernqaj yog yooj yim kom pom tseeb, kev teeb tsa thiab coj los ntawm cov khoom siv kho qhov muag, tuaj yeem tso rau hauv qhov tsim nyog ntawm qhov chaw ua haujlwm, thiab tuaj yeem coj los ntawm cov cuab yeej lossis cov teeb meem nyob ib ncig ntawm qhov chaw ua haujlwm, lwm txoj cai vuam vim qhov txwv saum no thiab tsis tuaj yeem ua si ;
(5) Qhov chaw ua haujlwm tuaj yeem tso rau hauv qhov chaw kaw (nyob rau hauv kev tswj kev nqus ntawm lub tshuab nqus lossis lub hauv paus roj sab hauv);
(6) lub lasernqaj tuaj yeem raug tsom rau thaj chaw me me thiab tuaj yeem txuas me me thiab ze qhov chaw kheej;
(7) ntau cov khoom siv weldable, tuaj yeem tuaj yeem ua ke nrog txhua lwm yam ntawm cov khoom siv heterogeneous;
(8) Yooj yim rau siv lub tshuab ua haujlwm siab, kuj tseem tuaj yeem tswj tau los ntawm digital lossis khoos phis tawm;
(9) thaum vuam nyias lossis txoj kab uas hla lub xov hlau, nws yuav tsis yooj yim li arc vuam kom muaj teeb meem ntawm rov qab;
(10) tsis cuam tshuam los ntawm kev sib nqus (arc vuam thiab hluav taws xob nqaj hlau vuam yog qhov yooj yim), tuaj yeem kho qhov vuam qhov chaw tau zoo;
(11) Ob hom hlau nrog cov khoom sib txawv ntawm lub cev (xws li cov khoom sib txawv) tuaj yeem sib dhos;
(12) Tsis muaj lub tshuab nqus tsev lossis xoo hluav taws xob tiv thaiv;
(13) yog tias cov hlau txuas sib tsoo, lub vuam tsoo qhov tob ntxiv rau qhov dav piv yuav ncav cuag 10: 1;
(14) lub cuab yeej tuaj yeem hloov mus rau xa cov nplais laser mus rau ntau qhov chaw ua haujlwm.
Laser welding Qhov Tsis Zoo
(1) vuam txoj haujlwm yuav tsum yog qhov tseeb tshaj, yuav tsum yog nyob rau hauv lub teeb ci tsom kab teeb pom kev;
(2) thaum lub vuam ua haujlwm yuav tsum siv cov tshuab clamping, nws yog qhov tsim nyog los xyuas kom meej tias qhov chaw kawg ntawm vuam qhov chaw thiab cov nqaj hlau yuav cuam tshuam rau lub vuam kev sib koom ua ke;
(3) Qhov chaw ua haujlwm qhov siab tshaj plaws weldable thickness tsis muaj txwv thiab qhov nws nkag siab tuab tshaj 19mm tsis haum rau laser vuam ntawm cov kab ntau lawm;
(4) siab reflectivity thiab siab thermal conductivity ntawm cov ntaub ntawv xws li txhuas, tooj thiab nws cov alloys, lub weldability yuav raug hloov los ntawm laser;
(5) Thaum ua cov laser beam vuam ntawm nruab nrab mus rau lub zog loj, lub plasma maub los yuav tsum siv los tshem cov roj ionized nyob ib ncig ntawm lub pas dej molten kom paub meej qhov rov tshwm ntawm weld dhau;
(6) lub zog hloov ua haujlwm siv qis heev, feem ntau tsawg dua 10%;
(7) kev nrawm nrawm ntawm weld dhau yuav ua rau muaj kev txhawj xeeb ntawm porosity thiab embrittlement;
(8) Cov khoom siv yog kim.
