1. Vuam tsom xam: 1. Cr18Ni9Ti stainless hlauФ159mm ib×12 hli loj yeeb nkab kab rov tav tsau pob qij txha yog tsuas yog siv nyob rau hauv cov khoom siv hluav taws xob nuclear thiab qee yam khoom siv tshuaj uas yuav tsum tau ua kom sov thiab kua qaub.Lub vuam yog qhov nyuaj thiab yuav tsum muaj kev sib koom ua haujlwm siab.Qhov saum npoo yuav tsum tau zoo li tus, nrog me ntsis protrusions thiab tsis muaj recesses.PT thiab RT yuav tsum tau kuaj xyuas tom qab vuam.Yav dhau los, TIG vuam lossis phau ntawv arc vuam tau siv.Cov yav tas muaj tsawg efficiency thiab tus nqi siab, thaum lub tom kawg yog ib qho nyuaj rau lav thiab muaj tsawg efficiency.Txhawm rau kom ntseeg tau thiab nce tus nqi, cov txheej hauv qab yog welded los ntawm TIG sab hauv thiab txheej txheej hlau filling, thiab MAG welding yog siv los sau thiab npog txheej txheej kom ua haujlwm tau zoo.2. Lub thermal expansion tus nqi thiab hluav taws xob conductivity ntawm 1Cr18Ni9Ti stainless hlau yog txawv heev los ntawm cov pa roj carbon steel thiab low-alloy steel, thiab lub pas dej molten muaj tsis zoo fluidity thiab tsis zoo tsim, tshwj xeeb tshaj yog thaum welding ntawm txhua txoj hauj lwm.Yav dhau los, MAG (Ar + 1%～2% O2) welding stainless hlau feem ntau tsuas yog siv rau cov vuam tiaj tiaj thiab tiaj tus fillet vuam.Nyob rau hauv MAG welding txheej txheem, qhov ntev ntawm vuam hlau yog tsawg tshaj li 10 hli, lub viav vias amplitude, zaus, ceev, thiab ntug dwell lub sij hawm ntawm lub vuam phom yog zoo sib koom ua ke, thiab qhov kev txiav txim yog sib koom ua ke.Kho lub kaum sab xis ntawm rab phom vuam txhua lub sijhawm, kom lub vuam seam nto npoo yog fused zoo zoo thiab zoo nkauj tsim kom ntseeg tau tias txhaws thiab npog txheej.

2. Vuam txoj kev: Cov khoom siv yog 1Cr18Ni9Ti, cov yeeb nkab loj yogФ159mm ib×12 hli, lub hauv paus yog tsim los ntawm phau ntawv argon arc vuam, cov roj sib xyaw (CO2 + Ar) shielded vuam thiab npog vuam, ntsug thiab kab rov tav tsau tag nrho txoj hauj lwm vuam.

3. Kev npaj ua ntej welding: 1. Ntxuav cov roj thiab cov av, thiab zom cov groove nto thiab ib ncig ntawm 10mm kom tau ib qho xim hlau.2. Xyuas seb cov dej, hluav taws xob, thiab roj hluav taws xob puas raug thaiv, thiab cov khoom siv thiab cov khoom siv tau zoo.3. Sib dhos raws li qhov loj me.Tack welding yog kho los ntawm tav (2 ntsiab lus, 7 ntsiab lus, thiab 11 ntsiab lus yog kho los ntawm tav), lossis hauv qhov zawj qhov chaw vuam, tab sis xyuam xim rau tack vuam.
