Kuwunika kwa Pre-Pressure Stage mu Nut Spot Welding

The pre-anzanu siteji ndi chigawo chovuta cha nati malo kuwotcherera ndondomeko, kumene ankalamulira mphamvu ntchito workpieces pamaso waukulu kuwotcherera gawo. Nkhaniyi ikuwunikira mozama momwe kuwotcherera kwa nati kusanachitike kupanikizika, ndikuwunikira kufunika kwake, njira yake komanso momwe kuwotcherera kumakhudzira.

1. Kumvetsetsa Gawo la Pre-Pressure Stage: Gawo la pre-pressure limaphatikizapo kugwiritsa ntchito mphamvu inayake kuzinthu zogwirira ntchito kusanachitike kuwotcherera kwenikweni. Mphamvu iyi imapanga kulumikizana kwapamtima pakati pa zogwirira ntchito ndikuwonetsetsa kulumikizana koyenera, komwe kuli kofunikira kuti pakhale mgwirizano wokhazikika komanso wodalirika.
2. Kufunika kwa Pre-Pressure Stage: Gawo la pre-pressure limakhala ndi gawo lofunikira pakuwotcherera malo a mtedza:

• Kuyanjanitsa: Mphamvu yogwiritsidwa ntchito imawonetsetsa kuti zogwirira ntchito zikugwirizana bwino, kuchepetsa mipata yomwe ingakhalepo kapena kusanja bwino.
• Kulumikizana Kwabwino: Kulumikizana kowonjezereka pakati pa zogwirira ntchito kumathandizira kusamutsa kutentha koyenera panthawi yotentha.
• Ubwino Wogwirizana Weld: Kupanikizika kokwanira kumabweretsa kutenthedwa kwa yunifolomu ndi kutuluka kwa zinthu, zomwe zimatsogolera ku khalidwe la weld losasinthika.

3. Kachitidwe ka Pre-Pressure Stage: a. Kukonzekera kwa workpiece: Zogwirira ntchito zimayikidwa bwino ndikulumikizidwa kuti ziwotcherera. b. Electrode Engagement: Ma electrode amalumikizana ndi zida zogwirira ntchito, ndikupanga masinthidwe omwe amafunidwa. c. Kugwiritsa Ntchito Mphamvu Yowongolera: Mphamvu yodziwikiratu imagwiritsidwa ntchito pazogwirira ntchito, ndikupanga kulumikizana kwapamtima. d. Kuyang'anira Mphamvu: Mphamvu yogwiritsidwa ntchito imayang'aniridwa kuti iwonetsetse kuti ndiyolondola komanso yosasinthika.
4. Impact on Welding Process: Kupambana kwa pre-pressure siteji kumakhudza mwachindunji zotsatira zonse zowotcherera:

• Kuyanjanitsa koyenera kumalepheretsa mipata yomwe ingayambitse mafupa ofooka kapena ma welds osagwirizana.
• Kukanikizana kosakwanira kungayambitse kusalumikizana bwino, zomwe zimapangitsa kuti kutentha kwapakati komanso kuchepa kwa weld.
• Mphamvu yochulukirapo ingayambitse kuwonongeka kwa zinthu kapena kuwonongeka kwa ma elekitirodi, zomwe zimakhudza magawo otsatirawa.

Gawo la pre-pressure ndi gawo lofunikira kwambiri pakuwotcherera madontho a nati, kuwonetsetsa kulumikizana bwino, kukhudzana, ndi kutengera kutentha kofanana pakati pa zogwirira ntchito. Pochita sitejiyi molondola, opanga akhoza kukhazikitsa maziko a njira yowotcherera yopambana, zomwe zimapangitsa kuti zikhale zolimba, zogwirizana, komanso zolimba. Kugwiritsa ntchito mphamvu moyenera, kuyika ma elekitirodi, ndi kuyang'anitsitsa mosalekeza kumathandizira kuti tipeze zotsatira zabwino panthawi ya pre-pressure.
