Kusankha zida zoperekera zabwino kwambiri komanso zokolola pakuwotcherera zimapitilira mphamvu yamagetsi kapena mfuti yowotcherera - zowotchera zimagwiranso ntchito yofunika. Maupangiri olumikizana nawo, makamaka, atha kupanga kusiyana kwakukulu pakati pa kuyendetsa bwino njira ndikupeza nthawi yopumira kuti athetse mavuto. Kusankha njira yoyenera yolumikizirana ndi ntchitoyo kungakhudzenso phindu la ntchito yowotcherera.
Maupangiri olumikizana ndi omwe ali ndi udindo wosamutsa magetsi owotcherera ku waya pamene akudutsa kuti apange arc. Momwemonso, mawaya amayenera kudutsa mosavutikira, pomwe amalumikizanabe ndi magetsi.
Upangiri wolumikizana nawo ungapangitse kusiyana kwakukulu pakati pa kugwiritsa ntchito njira yowotcherera bwino ndikuwonjezera nthawi yochepetsera kuti mukonze zovuta, komanso zitha kukhudza phindu la ntchito yowotcherera.
Pazifukwa izi, ndikofunikira nthawi zonse kusankha nsonga yolumikizirana yapamwamba. Ngakhale kuti malondawa atha kukhala okwera mtengo pang'ono kuposa zotsika mtengo, pali phindu lanthawi yayitali kunyalanyaza mtengo wogulidwa wamtsogolo.
Kuphatikiza apo, maupangiri olumikizana apamwamba kwambiri amapangidwa kuti azitha kulolerana ndi makina, ndikupanga kulumikizana kwabwinoko kwamafuta ndi magetsi. Zitha kukhalanso ndi bore losalala lapakati, zomwe zimapangitsa kuti mawaya asakanike pang'ono pamene waya akudutsa. Izi zikutanthawuza kudyetsa mawaya mosasinthasintha mosakoka pang'ono, zomwe zimathetsa zovuta zomwe zingachitike.
Malangizo apamwamba kwambiri okhudzana nawo angathandizenso kuchepetsa kuyatsa (kupangika kwa weld mkati mwa nsonga yolumikizirana) ndikuthandizira kupewa arc yosokonekera chifukwa cha kusagwirizana kwamagetsi. Amakondanso kukhala nthawi yayitali.
Kusankha zinthu zoyenera ndi kukula kwake
Maupangiri olumikizana omwe amagwiritsidwa ntchito powotcherera semi-automatic MIG nthawi zambiri amakhala ndi mkuwa. Nkhaniyi imapereka ma conductivity abwino amafuta ndi magetsi kuti alole kusamutsidwa kwanthawi zonse ku waya, komanso kukhala kolimba mokwanira kupirira kutentha komwe kumapangidwa panthawi yowotcherera. Pa kuwotcherera kwa robotic, makampani ena amasankha kugwiritsa ntchito nsonga zokulirapo za chrome zirconium, chifukwa izi ndizovuta kuposa zamkuwa ndipo zimapirira nthawi yowonjezereka ya pulogalamu yodzichitira yokha.
Nthawi zambiri, kugwiritsa ntchito nsonga yolumikizana yomwe ikufanana ndi kukula kwa waya kumabweretsa zotsatira zabwino. Komabe, mawaya akadyetsedwa kuchokera ku ng'oma (monga ma 500 pounds ndi kukulirapo) kapena kugwiritsa ntchito waya wolimba, nsonga yolumikizira yocheperako imatha kupititsa patsogolo ntchito yowotcherera. Chifukwa mawaya ochokera ku ng'oma amakhala opanda kuponyedwa pang'ono, amadya kudzera pansonga yolumikizirana osalumikizana pang'ono kapena osalumikizana - kukhala ndi kabowo kakang'ono kumapangitsa kuti wayayo azithamanga kwambiri, zomwe zimapangitsa kuti magetsi aziyenda kwambiri. Kuchepetsa nsonga yolumikizana, komabe, kumatha kukulitsa mikangano, zomwe zimapangitsa kuti mawaya azidya molakwika komanso, mwina, kuwotcha.
Kumbali ina, kugwiritsa ntchito nsonga yokulirapo kumatha kuchepetsa kusamutsa komwe kulipo ndikuwonjezera kutentha kwa nsonga, zomwe zingayambitsenso kuyaka kwa waya. Mukakayikira kusankha nsonga yolumikizirana ndi kukula koyenera, funsani wopanga wodalirika kapena wogawa zowotcherera.
Monga njira yabwino, nthawi zonse yang'anani kulumikizana pakati pa nsonga yolumikizirana ndi cholumikizira mpweya kuti mutsimikizire kuti ndichotetezeka. Choncho, kugwirizana kotetezeka kumachepetsa mphamvu zamagetsi zomwe zingayambitse kutentha kwambiri.
Kumvetsetsa kulumikizana nsonga recess
Kulumikizana nsonga yopuma imatanthawuza kuyika kwa nsonga yolumikizirana mkati mwa mphuno ndipo ndichinthu chofunikira kwambiri chomwe chimathandizira mtundu wa weld, zokolola komanso mtengo wake pakuwotcherera. Mwachindunji, nsonga yolondola yolumikizirana imatha kuchepetsa mwayi wa spatter mochulukira, porosity ndi kuwotcha kapena kuwotcha pazinthu zowonda kwambiri. Zingathandizenso kuchepetsa kutentha kowala komwe kungapangitse kuti nsonga yolumikizana isanakwane.
Kupumira kwa nsonga yolumikizirana kumakhudzanso chomata cha waya, chomwe chimatchedwanso kukulitsa kwa electrode. Kupumira kwakukulu, ndipamenenso chomangira chimakhala chachitali komanso mphamvu yamagetsi imakwera. Chifukwa chake, izi zimapangitsa kuti arc ikhale yosakhazikika. Pachifukwachi, chomata chabwino kwambiri chawaya nthawi zambiri chimakhala chachifupi kwambiri chololedwa kugwiritsa ntchito; imapereka arc yokhazikika komanso kulowa bwino kwamagetsi otsika. Malo omwe amalumikizana nawo ndi 1/4-inch recess, 1/8-inch recess, flush ndi 1/8-inch extension. Onani Chithunzi 1 pamapulogalamu ovomerezeka pa chilichonse.

Kutalikitsa moyo wolumikizana nawo
Kulephera kwa nsonga yolumikizirana kumatha chifukwa cha zinthu zingapo, kuphatikiza kuyatsa, kuvala kwamakina ndi magetsi, njira zowotcherera zosakwanira (mwachitsanzo, kusiyanasiyana kwa mbali yamfuti ndi nsonga yofikira kuntchito [CTWD]), komanso kutentha kochokera ku zinthu zoyambira, zomwe ndizofala kwambiri m'malo olumikizirana ndi ma weld kapena malo otsekeka.
Ubwino wa waya womwe umagwiritsidwa ntchito ungakhudzenso moyo wolumikizana nawo. Waya wosawoneka bwino nthawi zambiri amakhala ndi chitsulo chosafunikira kapena helix chomwe chingapangitse kuti azidya molakwika. Izi zingalepheretse waya ndi nsonga yolumikizana kuti isalumikizidwe bwino kudzera pa bore, zomwe zimapangitsa kuti pakhale kutsika kwambiri komanso kukana kwamagetsi. Izi zitha kupangitsa kulephera kwa nsonga yolumikizana mwachangu chifukwa cha kutentha kwambiri, komanso kusakhala bwino kwa arc. Kuti muwonjezere moyo wolumikizana nawo, lingalirani izi:
• Gwiritsani ntchito masikono oyendetsa bwino kuti muwonetsetse kuti mawaya akuyamwitsa bwino.
• Wonjezerani kuthamanga kwa mawaya ndikutalikitsa CTWD kuti muchepetse kuyatsa.
• Sankhani maupangiri olumikizana ndi malo osalala kuti mupewe kugunda kwa waya.
• Dulani chingwe chamfuti cha MIG kutalika koyenera kuti waya adutse bwino.
• Kutsika kwa kutentha kwa ntchito, ngati kuli kotheka, kuchepetsa kuvala kwa magetsi.
• Gwiritsani ntchito zingwe zamagetsi zazifupi ngati kuli kotheka kuti muzitha kudya mawaya osalala. Ngati zingwe zazitali zamagetsi ndizofunikira, yesetsani kuchepetsa malupu kuti muteteze kinking.
Nthawi zina, kungakhale kofunikira kusinthira kumfuti ya MIG yoziziritsidwa ndi madzi kuti zithandizire kusunga zinthu zakutsogolo, kuphatikiza nsonga yolumikizirana, kuzizira komanso kuthamanga kwa nthawi yayitali.
Makampani akuyeneranso kuganizira zotsata kagwiritsidwe ntchito ka maupangiri olumikizana nawo, ndikuzindikira kusintha kwakukulu ndikuwongolera molingana ndi njira zina zodzitetezera. Kuthana ndi nthawi yocheperako posachedwa kungathandize makampani kuchepetsa ndalama zosafunikira pakuwerengera, komanso kuwongolera bwino komanso zokolola.
