Zomwe Zimayambitsa Mibulu pa Weld Points mu Makina Owotcherera Apakati Pafupipafupi a Spot?

Makina owotcherera apakati pafupipafupi amagwiritsidwa ntchito kujowina zigawo zachitsulo m'mafakitale osiyanasiyana.Komabe, chimodzi mwazovuta zomwe ogwira ntchito angakumane nazo ndi kupanga ma thovu kapena ma voids pamalo owotcherera.Nkhaniyi ikufotokoza zifukwa zomwe ma thovu amawotchera mawanga apakati pafupipafupi ndikukambirana njira zothetsera vutoli.

Zifukwa za Bubbles pa Weld Points:

1. Zowononga Pamwamba:Chimodzi mwazinthu zomwe zimayambitsa thovu pamalo owotcherera ndi kupezeka kwa zonyansa, monga mafuta, mafuta, dzimbiri, kapena dothi, pamwamba pa chitsulo chowotcherera.Zonyansazi zimatha kuphwera panthawi yowotcherera, zomwe zimatsogolera kupanga thovu.
2. Oxidation:Ngati zitsulo sizikutsukidwa bwino kapena kutetezedwa bwino, makutidwe ndi okosijeni amatha kuchitika.Malo okhala ndi okosijeni amatha kusakanikirana nthawi yowotcherera, zomwe zimapangitsa kuti pakhale mipata kapena voids.
3. Kupanikizika Kosakwanira:Kuthamanga kosagwirizana kapena kosakwanira kwa electrode kungalepheretse kusakanikirana kwachitsulo koyenera.Izi zingayambitse mipata pakati pa zitsulo, zomwe zimapangitsa kuti thovu lipangike.
4. Kuwotcherera Kusakwanira Panopa:Kuwotcherera ndi madzi osakwanira kungayambitse kusakanizika kosakwanira pakati pa zitsulo.Zotsatira zake, mipata imatha kupanga, ndipo ming'oma imatha kuwuka chifukwa cha zinthu za vaporized.
5. Kuwonongeka kwa Electrode:Ma elekitirodi omwe amagwiritsidwa ntchito powotcherera pamalo amatha kuipitsidwa ndi zinyalala pakapita nthawi, zomwe zimakhudza mtundu wa weld.Maelekitirodi owonongeka angayambitse kusakanizika bwino komanso kukhalapo kwa thovu.
6. Zowotcherera Zolakwika:Kuyika zowotcherera molakwika, monga kuwotcherera pano, nthawi, kapena mphamvu ya electrode, kungayambitse kusakanizika kokwanira komanso kupanga thovu.

Mayankho Othana ndi Ma Bubbles ku Weld Points:

1. Kukonzekera Pamwamba:Tsukani bwino ndi kutsuka zitsulo pamwamba pa zitsulo musanawotchere kuti muchotse zonyansa zilizonse zomwe zingapangitse kupangika kwa thovu.
2. Chitetezo Pamwamba:Gwiritsani ntchito zokutira zoyenera zothira okosijeni kapena mankhwala kuti mupewe okosijeni pamalo achitsulo.
3. Konzani Pressure:Onetsetsani kuti kukakamiza kwa electrode ndikofanana komanso koyenera kwa zida zomwe zikuwotcherera.Kupanikizika kokwanira kumathandiza kukwaniritsa kusakanikirana koyenera ndikupewa mipata.
4. Zowotcherera Zolondola Panopa:Khazikitsani kuwotcherera panopa malinga ndi mfundo za zipangizo ndi ndondomeko kuwotcherera.Kukwanira kwapano ndikofunikira kuti mukwaniritse zowotcherera mwamphamvu komanso zopanda thovu.
5. Kukonza Ma Electrode Nthawi Zonse:Sungani maelekitirodi aukhondo komanso opanda zinyalala kuti muwonetsetse kuti akugwira ntchito bwino komanso kupewa zovuta zokhudzana ndi kuipitsidwa.
6. Kusintha kwa Parameter:Yang'anani kawiri ndikusintha magawo awotcherera ngati pakufunika kuti muwonetsetse kusakanikirana koyenera ndikuchepetsa chiopsezo chopanga thovu.

Kukhalapo kwa thovu pamalo owotcherera m'makina apakati pafupipafupi amatha kukhudza kwambiri kukhulupirika ndi kukhulupirika kwa ma welds.Kumvetsetsa zomwe zingayambitse nkhaniyi n'kofunika kwambiri kuti ogwira ntchito atengepo njira zodzitetezera ndikugwiritsa ntchito njira zothetsera kuphulika.Kupyolera mukukonzekera bwino pamwamba, kusunga kupanikizika kosasinthasintha, kugwiritsa ntchito zowotcherera zoyenera, ndikuonetsetsa kuti ma electrode ali aukhondo, ogwira ntchito amatha kupititsa patsogolo njira zawo zowotcherera ndi kupanga ma weld apamwamba kwambiri, opanda thovu pa ntchito zosiyanasiyana.
