1. Chinangwa chekupinza simbi ndechei?
Mhinduro: ①Deredzai kuoma kwesimbi uye kuvandudza mapurasitiki, kuitira kufambisa kucheka uye kutonhora deformation kugadzirisa;②Kunatsa zviyo, yunifomu kuumbwa kwesimbi, kunatsiridza mashandiro esimbi kana kugadzirira kupisa kweramangwana kurapwa;③Bvisa zvakasara musimbi Kushushikana kwemukati kudzivirira deformation uye kuparuka.
2. Kudzima chii?Chinangwa chayo ndechei?
Mhinduro: Iyo yekupisa yekupisa nzira yekudziya simbi kune imwe tembiricha iri pamusoro peAc3 kana Ac1, ichiichengeta kweimwe nguva yenguva, wozoitonhodza nekumhanya kwakakodzera kuwana martensite kana bainite inonzi quenching.Chinangwa ndechekuwedzera kuoma, simba uye kupfeka kusagadzikana kwesimbi.
3. Ndezvipi zvakanakira uye zvisingabatsiri zve manual arc welding?
Mhinduro: A. Zvakanakira
(1) Maitiro acho anochinjika uye anochinjika;(2) Unhu hwakanaka;3) Zviri nyore kudzora deformation uye kuvandudza kushushikana kuburikidza nekugadzirisa maitiro;(4) Chigadzirwa chacho chiri nyore uye chiri nyore kushanda.
B. Zvakaipa
(1) Zvinodiwa zvevelders zvakakwirira, uye hunyanzvi hwekushanda uye ruzivo rwevagadziri zvinokanganisa zvakananga kunaka kwezvigadzirwa.
(2) mamiriro ekushanda asina kunaka;(3) kuderera kwezvibereko.
4. Ndezvipi zvakanakira uye zvakaipira pasi pemvura arc welding process?
Mhinduro: A. Zvakanakira
(1) Kubudirira kwekugadzirwa kwepamusoro.(2) Hunhu hwakanaka;(3) Chengetedza zvinhu uye simba remagetsi;(4) Kuvandudza mamiriro ekushanda uye kuderedza kushanda nesimba
B. Zvakaipa
(1) Chete yakakodzera kune yakachinjika (yakarerekera) chinzvimbo welding.(2) Zvakaoma kupinza masimbi ane oxidizing uye alloys akadai sealuminium uye titanium.(3) Midziyo yacho yakanyanya kuoma.(4) Kana ikozvino iri pasi pe100A, kugadzikana kwearc hakuna kunaka, uye haikodzeri welding mahwendefa matete ane ukobvu hwepasi pe1mm.(5) Nekuda kwedziva rakadzika rakanyungudutswa, rinonzwa zvakanyanya kune pores.
5. Ndeapi mazano akazara ekusarudza groove?
Mhinduro:
① Inogona kuve nechokwadi chekupinda kweiyo workpiece (kudzika kwekupinda kwebhuku re arc welding kazhinji 2mm-4mm), uye yakanakira kushanda kwewelding.
②Chimiro chegorofu chinofanira kunge chiri nyore kugadzirisa.
③ Kuvandudza kugadzirwa kwewelding uye chengetedza welding tsvimbo zvakanyanya sezvinobvira.
④ Deredza deformation yeworkpiece mushure mekushongedza zvakanyanya sezvinobvira.
6. Chii chinonzi weld shape factor?Chii chiri hukama hwayo nemhando ye weld?
Mhinduro: Panguva yekubatanidza welding, chiyero pakati pehupamhi hweweld (B) uye yakaverengerwa ukobvu (H) yeweld pamuchinjikwa-chikamu chesingle-pass weld, ndiko kuti, ф=B/H, inonzi. iyo weld fomu factor.Iyo diki iyo weld shape coefficient, iyo yakamanikana uye yakadzika iyo weld, uye welds akadaro anotarirwa pore slag inclusions uye kuputika.Naizvozvo, iyo weld shape factor inofanirwa kuchengetedza imwe kukosha.
7. Ndezvipi zvinokonzera undercut uye nzira yekudzivirira nayo?
Mhinduro: Zvikonzero: kunyanya nekuda kwekusarudzwa kwakashata kwemaitiro ekugadzirisa maparameter, kuwandisa kwechikafu ikozvino, kureba kwearc, kukurumidza kusina kukodzera kwekutakura uye matanda emagetsi, nezvimwewo.
Nzira yekudzivirira: sarudza iyo chaiyo welding ikozvino uye welding kumhanya, iyo arc haigone kutambanudzwa kureba, uye tenzi nzira chaiyo uye kona yekutakura tambo.
8. Ndezvipi zvikonzero uye nzira dzekudzivirira dze weld surface saizi isingaite zvinodiwa?
Mhinduro: Chikonzero ndechekuti groove angle ye weldment haina kunaka, gaka regungano harina kuenzana, kukurumidza kumhanyisa hakuna kunaka kana nzira yekutakura mitsetse haina kunaka, tsvimbo yekushongedza uye kona haina kusarudzwa kana kuchinjwa.
Kudzivirira nzira Sarudza yakakodzera groove angle uye gungano clearance;sarudza nemazvo iyo welding process paramita, kunyanya kukosha kwazvino welding uye tora yakakodzera nzira yekushandisa uye kona kuti ive nechokwadi chekuti weld chimiro chakafanana.
