Pores mu weld seam ndi nkhani wamba khalidwe nthawikuwotcherera kwa robot. Kukhalapo kwa pores kungayambitse kuchepa kwa mphamvu ya welds, ndipo ngakhale kuyambitsa ming'alu ndi fractures. Zifukwa zazikulu zopangira pores mu ma welds a robot ndi awa:
1. Kusatetezedwa kwa gasi:
Pa kuwotcherera ndondomeko, kotunga zoteteza mpweya (monga argon, mpweya woipa, etc.) ndi osakwanira kapena osagwirizana, amene amalephera bwino kudzipatula mpweya, nayitrogeni, etc. mu mlengalenga, chifukwa mpweya kusanganikirana mu Sungunu dziwe ndi kupanga pores.
2. Kusasamalira bwino kwa zinthu zowotcherera ndi zida zoyambira:
Pali zonyansa monga madontho amafuta, dzimbiri, chinyezi, ndi masikelo a oxide pamwamba pa zinthu zowotcherera kapena zitsulo zoyambira. Zonyansazi zimawola pakatentha kwambiri kuti zitulutse mpweya, womwe umalowa m'dziwe losungunuka ndikupanga pores.
3. Zosayenera kuwotcherera magawo magawo:
Ngati mphamvu yamakono, magetsi, ndi kuwotcherera ndipamwamba kwambiri kapena kutsika kwambiri, zomwe zimapangitsa kuti dziwe losungunuka likhale losakwanira komanso kuti mpweya usatuluke bwino; Kapena ngati mbali yowomba ya gasi wotetezayo ndi yosayenera, imatha kukhudza chitetezo cha gasi.
4. Mapangidwe a weld osayenerera:
Ngati kusiyana pakati pa ma weld seams ndi kwakukulu kwambiri, madzi amadzimadzi a chitsulo chosungunuka ndi osauka, ndipo mpweya ndi wovuta kutulutsa; Kapena mawonekedwe a weld seam ndi ovuta, ndipo mpweya siwosavuta kuthawa pakuya kwa seam weld.
5. Kutentha kwakukulu m'malo owotcherera:
Chinyezi chamumlengalenga chimawola kukhala gasi wa haidrojeni pa kutentha kwambiri, komwe kumakhala kusungunuka kwambiri mu dziwe losungunuka ndipo sikutha kuthawa munthawi yozizirira, ndikupanga pores.
Njira zothetsera vuto la porosity mu ma welds a robot ndi awa:
1. Konzani chitetezo cha gasi:
Onetsetsani kuti chiyero cha mpweya woteteza chikugwirizana ndi muyezo, kuthamanga kwapakati kumakhala kochepa, ndipo mtunda pakati pa nozzle ndi msoko wowotcherera ndi woyenera, kupanga chitetezo chabwino cha mpweya.
●Gwiritsani ntchito mawonekedwe oyenera a gasi ndi chiŵerengero chosakanikirana, monga kugwiritsa ntchito ndodo zowotcherera za hydrogen kapena mawaya otsika kwambiri, kuti muchepetse gwero la mpweya wa haidrojeni.
2. Chithandizo chokhwima pamwamba:
Bwinobwino kuyeretsa pamwamba pakuwotcherera zinthundi zitsulo zoyambira musanayambe kuwotcherera, chotsani zonyansa monga mafuta, dzimbiri, ndi chinyezi, ndipo perekani chithandizo cha preheating ngati kuli kofunikira.
Kwa malo omwe chinyezi chikhoza kuchitika panthawi yowotcherera, tengani njira zowumitsa, monga kugwiritsa ntchito chowumitsira msoko kapena kutenthetsa ntchito.
3. Sinthani magawo awotcherera:
Sankhani liwiro loyenera lapano, ma voliyumu, ndi kuwotcherera kutengera zinthu zowotcherera, zinthu zoyambira, ndi malo owotcherera kuti mutsimikizire kugwedezeka pang'ono ndi kuthawa kwa mpweya padziwe losungunuka.
Sinthani mawonekedwe akuwomba a gasi woteteza kuti muwonetsetse kuti mpweyawo umakwirira msoko wowotcherera.
4. Sinthani kapangidwe ka weld:
Yang'anirani kusiyana kwa msoko wowotcherera mkati mwaoyenera kuti musamakhale wamkulu kapena wocheperako.
Pazowotcherera zovuta, njira monga kuwotcherera magawo, chitsulo chodzaza zitsulo, kapena kusintha njira zowotcherera zitha kugwiritsidwa ntchito kukonza mikhalidwe yotulutsa mpweya.
5. Kuwongolera malo owotcherera:
Yesetsani kuwotcherera pamalo owuma komanso mpweya wabwino kuti mupewe chinyezi chambiri.
Kwa madera omwe chinyezi sichingalamuliridwe, njira monga kugwiritsa ntchito hygroscopics ndi kuwotcherera msoko kutenthetsa zitha kuganiziridwa kuti zichepetse mphamvu ya chinyezi.
6. Kuyang'anira ndi kuyang'anira khalidwe:
Yang'anani nthawi zonse magwiridwe antchito a zida zowotcherera, monga ma mita otaya mpweya, ma nozzles amfuti, ndi zina zambiri, kuti muwonetsetse kuti ali ndi ntchito yabwino.
Kuwunika kwanthawi yeniyeni kwa njira yowotcherera, monga kugwiritsa ntchito njira yowunikira njira yowotcherera, kuti muzindikire mwachangu ndikusintha magawo omwe sali bwino.
Chitani mayeso osawononga (monga kuyesa kwa akupanga, kuyesa kwa radiographic, ndi zina zotero) mutatha kuwotcherera kuti muzindikire ndikuchiza ma weld okhala ndi porosity. Kugwiritsiridwa ntchito kwathunthu kwa njira zomwe tazitchulazi kungathe kuchepetsa mbadwo wa pores mu ma welds a robot ndikuwongolera khalidwe la kuwotcherera.
Zomwe zimayambitsa porosity mu ma welds a robot ndi kuipitsidwa ndi zinthu zowotcherera pamwamba, chitetezo chokwanira cha gasi, kuwongolera kosayenera kwa kuwotcherera pakali pano ndi magetsi, komanso kuthamanga kwambiri. Kuti tithane ndi vutoli, tifunika kuchitapo kanthu, kuphatikiza kugwiritsa ntchito zida zowotcherera zoyera, kusankha mpweya wodzitchinjiriza komanso kuwongolera kuchuluka kwa kayendedwe kake, kukhazikitsa zowotcherera moyenera, ndikuwongolera liwiro la kuwotcherera malinga ndi momwe zilili. Pokhapokha pothana ndi zinthu zingapo nthawi imodzi yomwe tingapewe ndikuthetsa vuto la porosity mu ma welds a robot, ndikuwongolera mtundu wa kuwotcherera.
