Zifukwa Zomwe Zimayambitsa Kupaka ndi Kuwotcherera Zofooka mu Resistance Spot Welding?

Resistance spot kuwotcherera ndi njira yowotcherera yomwe imagwiritsidwa ntchito kwambiri pomwe zidutswa ziwiri zachitsulo zimalumikizana pogwiritsa ntchito kutentha ndi kukakamiza pazifukwa zina.Komabe, njirayi imatha kukumana ndi zovuta monga splattering ndi welds ofooka.M’nkhani ino, tiona zifukwa zofala zimene zimachititsa mavutowa ndi kukambirana njira zothetsera mavuto.

 Kumvetsetsa I

1. Malo Oyipitsidwa:

• Nkhani:Zitsulo zakuda kapena zoipitsidwa zimatha kupangitsa kuti weld asamakhale bwino.
• Yankho:Onetsetsani kuti zowotcherera ndi zoyera komanso zopanda dothi, dzimbiri, mafuta, kapena zoipitsa zina zilizonse.Chotsani bwino zitsulo musanawotcherera.

2. Kupanikizika kosakwanira:

• Nkhani:Kuwotchera ndi kupanikizika kosakwanira kungapangitse kuti ma welds ofooka, osakwanira.
• Yankho:Sinthani makina owotcherera kuti agwiritse ntchito mphamvu yoyenera pazinthu zomwe zikuwotchedwa.Onetsetsani mphamvu yoyenera ya electrode.

3. Zowotcherera Zolakwika:

• Nkhani:Kugwiritsa ntchito zowotcherera molakwika monga nthawi, zamakono, kapena kukula kwa ma elekitirodi kumatha kupangitsa kuti ma welds asungunuke komanso ofooka.
• Yankho:Tsatirani malangizo a wopanga pazowotcherera magawo.Yesani ndi zoikamo ngati pakufunika, koma nthawi zonse mkati mwa malire otetezeka.

4. Electrode Wear:

• Nkhani:Maelekitirodi otopa kapena owonongeka angayambitse kutentha kosasinthasintha ndi ma welds ofooka.
• Yankho:Nthawi zonse fufuzani ndi kusunga maelekitirodi.Bwezerani m'malo pamene zikuwonetsa kuti zatha.

5. Kusakwanira bwino:

• Nkhani:Ngati mbali zowotcherera sizikugwirizana bwino, zingayambitse zowotcherera zofooka.
• Yankho:Onetsetsani kuti zogwirira ntchito zalumikizidwa bwino ndikumangika musanawotchererane.

6. Kusagwirizana kwa Zinthu:

• Nkhani:Zida zina sizowotcherera mosavuta pogwiritsa ntchito kuwotcherera malo oletsa.
• Yankho:Onetsetsani kuti zida zomwe mukuyesera kuziwotcherera zikugwirizana ndi njirayi.Ganizirani njira zina zowotcherera pazinthu zosagwirizana.

7. Kutentha kwambiri:

• Nkhani:Kutentha kwambiri kungayambitse kuphulika ndi kuwonongeka kwa weld zone.
• Yankho:Yang'anirani nthawi yowotcherera ndi yapano kuti mupewe kutenthedwa.Gwiritsani ntchito njira zoziziritsira zoyenera ngati kuli kofunikira.

8. Osauka Electrode Contact:

• Nkhani:Kulumikizana kosagwirizana ndi ma elekitirodi ndi zida zogwirira ntchito kungayambitse ma welds ofooka.
• Yankho:Onetsetsani kuti maelekitirodi amalumikizana bwino ndi zitsulo.Sambani ndi kuvala maelekitirodi ngati pakufunika.

9. Kupanda Luso la Oyendetsa:

• Nkhani:Ogwiritsa ntchito osadziwa angavutike ndi njira yoyenera komanso zoikamo.
• Yankho:Perekani maphunziro ndi ziphaso kwa ogwira ntchito kuti apititse patsogolo luso lawo ndikumvetsetsa momwe ntchitoyi ikuyendera.

10. Kukonza Makina:-Nkhani:Kunyalanyaza kukonza kwanthawi zonse kungayambitse zovuta za zida zomwe zimakhudza mtundu wa kuwotcherera.-Yankho:Yang'anani nthawi zonse ndikusunga makina owotcherera kuti akhale abwino kwambiri.

Pomaliza, resistance spot kuwotcherera ndi njira yosunthika komanso yothandiza yowotcherera ikachitidwa moyenera.Kuti mupewe mavuto monga splattering ndi welds ofooka, ndikofunikira kuthana ndi zomwe zatchulidwa pamwambapa ndikugwiritsa ntchito njira zoyenera.Kusamalira pafupipafupi, kuphunzitsidwa koyenera, komanso kusamala mwatsatanetsatane ndizofunikira kwambiri kuti mukwaniritse ma welds apamwamba pama projekiti anu.
