1. Lub hom phiaj ntawm steel annealing yog dab tsi?
Teb: ① Txo qhov hardness ntawm cov hlau thiab txhim kho plasticity, thiaj li pab txhawb kev txiav thiab txias deformation ua;②Refine cov nplej, sib xyaw ua ke ntawm cov hlau, txhim kho kev ua haujlwm ntawm cov hlau lossis npaj rau kev kho cua sov yav tom ntej;③ Tshem tawm cov khoom seem hauv cov hlau sab hauv kom tsis txhob deformation thiab tawg.
2. Dab tsi yog quenching?Nws lub hom phiaj yog dab tsi?
Teb: Cov txheej txheem kev kho cua sov ntawm cov cua sov ntawm cov hlau mus rau qhov kub siab tshaj Ac3 lossis Ac1, khaws cia rau qee lub sijhawm, thiab tom qab ntawd txias nws ntawm qhov tsim nyog kom tau txais martensite lossis bainite yog hu ua quenching.Lub hom phiaj yog ua kom cov hardness, lub zog thiab hnav tsis kam ntawm steel.
3. Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm phau ntawv arc vuam?
Teb: A. Qhov zoo
(1) Cov txheej txheem yog hloov tau thiab hloov tau;(2) Qhov zoo yog qhov zoo;3) Nws yog ib qho yooj yim los tswj deformation thiab txhim kho kev ntxhov siab los ntawm kev hloov kho;(4) Cov cuab yeej siv tau yooj yim thiab yooj yim rau kev khiav lag luam.
B. Qhov tsis zoo
(1) Cov kev xav tau rau cov welders yog siab, thiab cov kev txawj ua haujlwm thiab kev paub ntawm cov welders ncaj qha cuam tshuam rau cov khoom zoo.
(2) kev ua haujlwm tsis zoo;(3) tsawg tsim tau.
4. Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm submerged arc vuam txheej txheem?
Teb: A. Qhov zoo
(1) High efficiency efficiency.(2) Zoo zoo;(3) Txuag cov ntaub ntawv thiab hluav taws xob;(4) Txhim kho kev ua haujlwm thiab txo kev siv zog ua haujlwm
B. Qhov tsis zoo
(1) Tsuas yog tsim rau kab rov tav (nruab nrab) txoj haujlwm vuam.(2) Tsis yooj yim rau weld heev oxidizing hlau thiab alloys xws li txhuas thiab titanium.(3) Cov cuab yeej siv tau yooj yim dua.(4) Thaum qhov tam sim no tsawg dua 100A, qhov arc stability tsis zoo, thiab nws tsis haum rau vuam nyias daim hlau nrog lub thickness ntawm tsawg dua 1 hli.(5) Vim lub pas dej sib sib zog nqus molten, nws yog rhiab heev rau pores.
5. Lub hauv paus ntsiab lus ntawm kev xaiv qhov zawj yog dab tsi?
Teb:
① Nws tuaj yeem ua kom qhov nkag mus ntawm qhov chaw ua haujlwm (qhov tob tob ntawm phau ntawv arc vuam feem ntau yog 2mm-4mm), thiab nws yooj yim rau kev siv vuam.
② Cov duab zawj yuav tsum yooj yim ua.
③ Txhim kho vuam tsim tau thiab txuag vuam rods ntau li ntau tau.
④ Txo qhov deformation ntawm lub workpiece tom qab vuam kom ntau li ntau tau.
6. Dab tsi yog qhov vuam zoo li cas?Dab tsi yog nws txoj kev sib raug zoo nrog cov weld zoo?
Teb: Thaum lub sij hawm fusion welding, qhov sib piv ntawm qhov dav ntawm qhov vuam (B) thiab xam thickness (H) ntawm qhov sib tsoo ntawm ib qho kev sib txuas, uas yog, ф = B / H, yog hu ua qhov weld form factor.Qhov me me ntawm weld zoo coefficient, qhov nqaim thiab sib sib zog nqus qhov vuam, thiab cov welds zoo li cov pore slag inclusions thiab tawg.Yog li ntawd, qhov zoo tshaj plaws weld zoo yuav tsum tuav ib qho nqi.
7. Dab tsi yog qhov ua rau undercut thiab yuav tiv thaiv nws li cas?
Teb: Ua rau: feem ntau yog vim kev xaiv tsis raug ntawm cov txheej txheem vuam tsis zoo, vuam tam sim no ntau dhau, arc ntev dhau lawm, kev thauj khoom tsis zoo thiab vuam rods, thiab lwm yam.
Txoj kev tiv thaiv: xaiv qhov tseeb vuam tam sim no thiab vuam ceev, lub arc tsis tuaj yeem ncav cuag ntev dhau, thiab paub txog txoj kev raug thiab lub kaum sab xis ntawm kev thauj cov sawb.
8. Yuav ua li cas yog vim li cas thiab kev tiv thaiv txoj kev weld nto qhov luaj li cas tsis tau raws li qhov yuav tsum tau?
Teb: Qhov ua rau yog tias lub kaum sab xis ntawm qhov vuam tsis raug, qhov sib dhos sib dhos tsis sib xws, qhov vuam ceev tsis raug lossis txoj kev thauj mus los ntawm cov sawb tsis raug, qhov vuam pas nrig thiab lub kaum sab xis raug xaiv los yog hloov tsis raug.
Txoj kev tiv thaiv Xaiv lub kaum sab xis tsim nyog thiab sib dhos tshem tawm;xaiv cov txheej txheem vuam kom raug, tshwj xeeb tshaj yog cov nqi vuam tam sim no thiab txais yuav txoj kev ua haujlwm tsim nyog thiab lub kaum sab xis kom ntseeg tau tias qhov vuam zoo ib yam.
