1. Kuchi mutuhasa kusolola zango lienyi?
Yankho: ①Chepetsani kuuma kwachitsulo ndikuwongolera pulasitiki, kuti muthandizire kudula ndi kukonza kuzizira;②Yenga njere, yunifolomu kapangidwe ka chitsulo, kusintha magwiridwe antchito achitsulo kapena kukonzekera kutentha kwamtsogolo;③Chotsani zotsalira muzitsulo Kupsinjika kwamkati kuti mupewe kupindika ndi kusweka.
2. Kodi kuzimitsa ndi chiyani?Kodi cholinga chake ndi chiyani?
Yankho: Njira yochizira kutentha yotenthetsera chitsulo ku kutentha kwina pamwamba pa Ac3 kapena Ac1, kuisunga kwa nthawi inayake, kenako ndikuyizizira pa liwiro loyenera kuti mupeze martensite kapena bainite imatchedwa quenching.Cholinga ndikuwonjezera kuuma, mphamvu ndi kuvala kukana kwachitsulo.
3. Kodi ubwino ndi kuipa kwa kuwotcherera arc pamanja ndi chiyani?
Yankho: A. Ubwino
(1) Njirayi ndi yosinthika komanso yosinthika;(2) Ubwino wake ndi wabwino;3) Ndiosavuta kuwongolera mapindikidwe ndikuwongolera kupsinjika kudzera pakusintha kwadongosolo;(4) Zida ndi zosavuta komanso zosavuta kugwiritsa ntchito.
B. Zoipa
(1) Zofunikira zowotcherera ndizazikulu, ndipo luso laowotcherera komanso luso laowotcherera limakhudza mwachindunji mtundu wazinthu.
(2) kusagwira ntchito bwino;(3) zokolola zochepa.
4. Kodi ubwino ndi kuipa kwa ndondomeko yowotcherera arc yomwe ili pansi pa madzi ndi yotani?
Yankho: A. Ubwino
(1) Kuchita bwino kwambiri.(2) Makhalidwe abwino;(3) Sungani zipangizo ndi mphamvu zamagetsi;(4) Kupititsa patsogolo malo ogwirira ntchito ndikuchepetsa mphamvu yantchito
B. Zoipa
(1) Oyenera okha kuwotcherera yopingasa (opendekeka) malo.(2) Zovuta kuwotcherera zitsulo zotulutsa okosijeni kwambiri ndi ma aloyi monga aluminium ndi titaniyamu.(3) Zida ndi zovuta kwambiri.(4) Pamene panopa ndi zosakwana 100A, arc bata si bwino, ndipo si oyenera kuwotcherera mbale woonda ndi makulidwe zosakwana 1mm.(5) Chifukwa cha dziwe lakuya losungunuka, limamva bwino pores.
5. Kodi mfundo zazikuluzikulu zosankha poyambira ndi ziti?
Yankho:
① Itha kuwonetsetsa kulowa kwa workpiece (kuzama kwa kuwotcherera kwa arc nthawi zambiri kumakhala 2mm-4mm), ndipo ndiyosavuta kugwiritsa ntchito kuwotcherera.
②Mawonekedwe a groove ayenera kukhala osavuta kukonza.
③ Kupititsa patsogolo ntchito zowotcherera ndikusunga ndodo zowotcherera momwe mungathere.
④ Chepetsani mapindidwe a workpiece mutatha kuwotcherera momwe mungathere.
6. Kodi weld shape factor ndi chiyani?Kodi ubale wake ndi weld quality ndi wotani?
Yankho: Pa kuwotcherera maphatikizidwe, chiŵerengero chapakati pa kukula kwa weld (B) ndi makulidwe owerengeka (H) a weld pa gawo limodzi la weld-pass, ndiko kuti, ф=B/H, amatchedwa. mawonekedwe a weld form.Zing'onozing'ono za weld mawonekedwe a coefficient, ang'onoang'ono ndi ozama kwambiri, ndipo ma welds oterewa amatha kuphatikizira pore slag ndi ming'alu.Chifukwa chake, mawonekedwe a weld ayenera kukhalabe ndi mtengo wina.
7. Kodi zimayambitsa undercut ndi momwe mungapewere?
Yankho: Zimayambitsa: makamaka chifukwa cha kusankha kosayenera kwa magawo owotcherera, kuchuluka kwa kuwotcherera pakali pano, arc yayitali kwambiri, kuthamanga kosayenera kwa ndodo zonyamula ndi zowotcherera, etc.
Njira yodzitetezera: sankhani liwiro loyenera kuwotcherera pano komanso liwiro la kuwotcherera, arc sangathe kutambasulidwa motalika kwambiri, ndipo dziwani njira yolondola komanso ngodya yonyamulira mzerewo.
8. Kodi zifukwa ndi njira zopewera zowotcherera sizikukwaniritsa zofunikira ndi ziti?
Yankho: Chifukwa chake ndi chakuti groove angle ya weldment ndi yolakwika, kusiyana kwa msonkhano ndi kosagwirizana, kuthamanga kwa kuwotcherera ndi kosayenera kapena njira yoyendetsera galimoto ndi yolakwika, ndodo yowotcherera ndi ngodya imasankhidwa molakwika kapena kusinthidwa.
Kupewa njira Sankhani koyenera poyambira ngodya ndi msonkhano chilolezo;molondola kusankha magawo kuwotcherera ndondomeko, makamaka kuwotcherera mtengo panopa ndi kutengera njira yoyenera ntchito ndi ngodya kuonetsetsa kuti kuwotcherera mawonekedwe yunifolomu.
